Zantrex Black Overview
Zantrex is a very popular, yet controversial weight loss supplement made by Zoller Labs.
First there was the original Zantrex 3 in the red bottle, which we’ve actually tested.
The side effects of the red bottle were just too much for some, and here’s just a sample of some of them that were left on our site back in 2015.
Then there was Zantrex 3 Blue which was the company’s answer to complaints of side effects caused by original.
The blue bottle is a GREAT fat burner, and is actually one of the best fat burners for women we’ve ever tested.
Now there’s Zantrex Black, the Accelerated Rapid Release Formula.
All three of the products in the line have the same stated goals, which are to:
-
- Burn fat
- Decrease appetite
- Give you energy
- Help you lose weight
But they each approach it in a different way.
We’ve reviewed Red and Blue in the past.We’ve even compared them.
So this time, we’re primarily dealing with Zantrex Black.

Zantrex Black, as stated above, is the option for people who want a fast acting weight loss supplement that they can use in conjunction with any sensible weight loss product.
The focus is on the quickness of both the initial energy boost, and the weight loss.
So if you’re looking for instant gratification, Zantrex Black is the one to choose.
Zantrex Black Ingredients and How They Work
Of course, the most important factor in whether or not a supplement works is the formula, so let’s get right to it.
Here’s a quick look at the label:
TheZantrex Blackformula includes:
- Niacinwhich increases blood flow.
It’s actually known to sometimes cause a warm “niacin fliush” where your skin gets a little red and tingly from the blood rushing through the blood vessels. - Protein: I’m not even sure why they included this as an ingredient in Zantrex Black, mainly because it only contains 0.5 grams. This dose is nowhere close to making any sort of reasonable difference.
The Zantrex Black Proprietary Blend which provides several sources of caffeine including:
- Green Tea which also provides fat burning, antioxidant ECGCs which have been shown to burn fat.
- Guarana Seed Extract: Commonly found in many other fat burners like Slim Trim and 1 M.R., Guarana is basically a stimulant that contains chemicals similar to caffeine.
- Yerba Mate Leaf Extract: Another stimulant which is actually rich in antioxidants due to its high concentration of polyphenols.
- Black Tea Leaf Extract
- Kola Seed Extract
- Trimethylxanthine (which is the chemical name for pure caffeine).
And other ingredients including:
- Maca Root Extractwhich increases the release of dopamine from the brain.
This improves mood and motivation to curb emotional eating. - Asian Ginseng Root which also improves blood flow to supply more nutrients and oxygen to your muscles while working out.
- Damiana Leaf Extract which elevates mood and suppresses appetite.
It may also inhibit the conversion of testosterone to estrogen. - Schizonepeta Flower Extract which is commonly used for colds and sore throats, but doesn’t seem to have a connection with weight loss that I’ve been able to find.
- Black Pepperwhich helps increase thermogenic activity in the body.
- Rhodiola Crenulata Root Extract which relieves anxiety and helps burn fat.
- Cacao Seed Extract which can reduce the production of fat cells.
Clearly, the formula is very caffeine heavy, but because it’s all couched within a proprietary blend, we don’t know any real numbers or actual amounts.
The whole blend totals 1,160 mg, and about half the ingredients are basically caffeine, but since they don’t reveal the amounts, we don’t know how much caffeine they’re putting in Zantrex Black.
Given that this is a Zantrex product, famous for being pretty speedy, my guess is it’s a lot.
How To Take Zantrex Black
The recommended dose is 2 softgels taken about 15 minutes before main meals.
You can take 1 or 2 as needed for energy, but it is not recommended that you take more than 6 in one day.
There is also a recommendation that you avoid additional caffeine when taking Zantrex Black.
I would also add another caution against taking Zantrex Blacktoo close to bedtime.
I would imagine it would interfere with a good night’s sleep.
Zantrex Black Reviews
Next to the formula, which we now know is extremely stimulant-heavy, the second most important factor in determining whether or not Zantrex Black is any good is what kind of feedback it gets from actual customers.
We’ve actually had about 40 people leave reviews of Zantrex Black on our site.
On the one had you have the positive experiences, like this one:
And this one:
And on the other hand, you have the NEGATIVE experiences that some have encountered:
And this one:
The positive Zantrex Black reviews outweigh the negative ones at about a 10:1 ratio, but I mean come on…
We’re not talking about people just saying things like:
- It didn’t work for me
- I didn’t feel any effects
- Doesn’t work
Instead we’re seeing things about blood pressure skyrocketing and near death experiences.
Since Zantrex Black is sold at Amazon.com, there are dozens of reviews to look at, and the opinions are widely varied when compared to the reviews on our site.
There are almost as many 1-star reviews as there are 5-star ones.
First here are a couple of the raves, all from verified purchases:
And here’s some of the feedback from unhappy customers:
As mentioned earlier, we actually have about40 customer reviews posted below, and the vast majority reflect those on Amazon.
Something important to make note of in the reviews is that even people that like Zantrex Black mention the side effects.
It’s mainly a matter of degree of tolerability that determines whether or not the reviews are good or bad.
There seems to be little question that Zantrex Black can increase your energy, and that’s the primary benefit users talk about.
But for some, the side effects are too much.
Zantrex Black Side Effects
There’s a lot of caffeine in Zantrex Black, so anyone who’s sensitive to the stuff should beware.
If you want to avoid jitters, a racing heartbeat, and sleeplessness, you may want to start out with just one pill at first.
That way, any side effects you do face will be mild and hopefully won’t last as long.
You’ll also want to stay away from additional sources of caffeine, such as coffee and soda.
The other common side effect is known as “The Niacin Flush”, which we talked about earlier.
The Zantrex Black formula has 30 mg, which is 150% of the daily recommended amount.
This much niacin often makes your skin red and makes you feel like your skin is burning up.
The feeling should only last a few minutes, but it can be very unpleasant, and even a little scary for some people.
Some users expect it, and just let it happen, knowing it will pass. For others, it’s too uncomfortable and turns them away from the product altogether.
Zantrex Black Pros and Cons
Advantages of Zantrex Black
- It’s affordable.
- Just about every Zantrex Blackreview from a customer that I’ve seen says it works as a great appetite suppressant.
Most people say it practically eliminates their appetites.
Disadvantages of Zantrex Black
- It’s got a boatload of caffeine, though we don’t know exactly how much because each of its caffeine sources are included in the proprietary blend that doesn’t offer amounts.
- Lots of people get side effects like stomach aches, headaches, and dizziness.
- You need to eliminate other sources of caffeine while you’re taking it.
Zantrex Black Compared With Zantrex Red and Zantrex Blue
Almost nobody questions whether or not each of these products woks for energy and appetite suppression. They all work. So we move on to side effects.
People who are sensitive to stimulants will have about an equal (and not pleasant) reaction to the Red and the Black. And they both work very well.
Zantrex Blue works as well, but seems to come with fewer problems.
Where to Buy
You can buy Zantrex Black in stores like Walmart, Target, and CVS or online directly through the product site or through sites like Amazon.com.
A bottle of 84 softgels sells for about $25 or less depending on where you go.
This is pretty low compared to similar products, but if that deters you, it shouldn’t necessarily because it is pretty effective in the short term.
Prices don’t vary too much so where you choose will come down to a matter of convenience.
Conclusion
Zantrex Black works.But anyone who doesn’t react well to caffeine or isn’t fond of the jittery feeling that certain stimulants cause will not feel good takingZantrex Black.
Even for people who don’t mind the feeling, I would recommend you treat Zantrex Black as a short term supplement to boost your efforts or push you through a stubborn plateau.
It’s not the kind of supplement you want to be taking month after month.
The heavy stimulant effects will probably keep you from wanting to take it month after month anyway, that is.
And if you do decide to try it, do so with caution.
Start with just one pill so you can experience any side effects more mildly. Be prepared for the Niacin Flush.
Drink a good amount of water and wait it out.
It shouldn’t be long, then you’ll be left with the energy and appetite suppression you’re looking for.

The worst
I took zantrex black for 2 days and it was going great. The 3rd day..... not so much. I took my 2nd dose of 2 caps. With in 10 minutes my face, neck, and cheat was on fire. Followed by the shakes, light headed, chest pains, and trouble breathing. My wife called 911. The firefighters took my BP and heart rate. My BP was 191/189 PULSE of 180.
Went to the er and given many meds for high BP and heart rate. After 2 hours it was back to normal. In my opinion it is not worth your life! This was a very scary moment for me. Note... i am a 25 year old male and weight 215 with NO health problems. Some people do just fine on these pills while others do not. Just be careful and pay attention to your symptoms if you begin to get "flush" or start burning.

Drew's Review
Today is the second day I'm taking this product. I haven't really taken anything before and I usually don't I take a lot of caffeine except for the occasional coffe or energy drink, so it's hitting me pretty hard. I've limited myself to two soft gels in the morning and then done for the day. Even so, I am taking this while on the paleo diet and it controls my appetite pretty well. The only thing I'd complain about is the jitteriness right after taking and the stomach ache that lasts for about a half hour. Other than that, this gives me lots of energy to work with considering I tend to get unmotivated.

WORKS!!
I have taken Zantrex Black for 3 days and have seen a significant change! I did have the Niacin Flush the first day but it didn't bother me. I probably would only use this to get over a plateau and not all the time due to the caffiene. Worked amazing for right after Thanksgiving!

Does the job!
WATER is the key to dispensing with the nasty side effects of face flushing, heart palpitations and tummy ache. you must take each softgel with at least 8 ounces of water. I take one softgel with 16 ounces of water and have no side effects with each dose. My appetite is well controlled and I find I have an abundant amount of energy for each workout. Using this to lose those final 15 pounds which are the hardest. Love this product!

Only on day two
After reading all of the horrible reviews I was skeptical if to actually give them a go. But since I'm a hardhead I bought them and tried them the next day. I drank about 8 oz before drinking the pills (2 softgels) and about 10 more ounces after drinking them. Within 20 minutes I have loads of energy and it controls my appetite. One thing though, I only take a dose a day. I couldn't imagine taking 6 pills in 24 hours. And yes I've lost weight overnight. Literally 5 lbs gone overnight. I was shocked. Even thought my scale was broken so I bought another lol. Yes it was true 5 lbs gone. And my stomach even looks different 🙂 super pleased with this product. I'll update again by the end of week one 🙂

Black
I've only been taking it for 5 days and I've lost 10 pounds already. My schedule doesn't allow much time for exercising right now so I needed the strongest version for now. The jitters have decreased daily and I find myself eating as a necessity, by that I mean I have to remind myself to eat, instead of eating as a hobby. I wish I had found these pills sooner!!

It really does work!
I have been taking Xantrex black for a couple months. I take two pills first thing in the morning with plenty of water. That's it. I have so.much energy. And have lost about 35 pounds already. My appetite has significantly decreased, I don't snack anymore, any all around feel great. I might get the niacin flush a couple days a week which is no biggie. No other side effects for me. It's a fantastic product. I will definitely keep taking it!

Works for humans like nitrous works on cars!
This product is to humans as nitrous works on cars. Too much and you'll blow your engine. I recommend taking only one pill at a time. Two pills is too much to start out at if your body is sensitive to caffeine. Do not take more than 5 a day though. 2-3 pills taken at different times of the day are good enough if you're in need of it. But the itchiness is really only temporarily, unless you take more than one at a time. Take one at a time! Otherwise you'll end up like these poor guys in these other reviews. And make sure you need to take the pill, because that much caffeine will keep you alert for a good while!

Awesome
I have been taking for about 3 months I love it I have lost 40 pounds and keeping on
10 out of 10 people found this review helpful.
I've been taking this for about 3 months now and I absolutely love it! I take 2 in the morning 2 at dinner and 2 at night! I was at 155 due to some steroids because of a bad back injury and 3 months later I'm back to my normal weight 124. These pills are amazing and if you work out with them or even just going to work, cleaning or just moving I think that give you more rapid results as well!

Fantastic!
I have been taking it steadily for about 2 weeks now. 2 at 7 am, 2 at 1 pm and 2 at 7 pm with my dinner (I eat once a day). I have dropped from a 44 waist to a 40! Only side effect I've had are headaches in the morning but they're bearable. Would definitely recommend

First day but love it
I took one pill in the morning knowing I'm somewhat caffeine sensitive. I drank 16 oz of water before I took it and 16 oz after and I had 0 side effects but a GREAT energy boost. I'm over weight and I'm doing a complete life style change. Today I ran 1/2 mile nature trail which is unheard of for me. About 5 hours later I took another pill and I still feel a good energy level (even had a water gun fight with my 4 year old after school) I'm not looking to "lose weight" I'm looking to become healthy and I REALLY believe these will help me achieve that.

Good till the third day
First two days were fine. I felt energized. Then the third day I took two soft gels in the morning like I normally do and all of a sudden my face and whole body started getting hot and itchy?? Made myself throw up and took a shower and it went away. Its good, but maybe I should limit myself to one pill in the morning.

Zantrex review
I tried Zantrex Black. I had no jitters, no nervousness. I did have the "niacin flush" but it was fine. I actually liked the sensation, it made me feel alive. I started with one 15mins. before my 3 meals for a couple a days, then I went to two 15mins. before meals. I'm doing great so far. I will send another review after a month on the Zantrex Black.

Chance's Review
I'v bee taking this pill on and off for months and if you get on a certain routine while taking it stick to it. But in all reality this pill does work if you take it right. Drink water and eat. This pill with the access of caffeine it does build up a ton of energy but for wrestler its a good product, it helps control your food intake and helps you burn off those few extra pounds to make it on weight. So over all its safe if you do it right.

So far so good
Hi everyone. I started taking the black pills last week. Not only is my energy up but I've already went from 235lbs to 224lbs. At first I did get nausea but realized I didn't eat.... It's funny because now I crave water. I drink like 4 16oz bottles within 3hrs of taking it which of course makes me run to the rest room every 30mins. Put my urine is clean.... Clear which means my system is flushed....which is a good thing. I'm so looking forward in seeing where I am in a month.

Don't Drink Caffeine
I've taken Zantrex Black for a full week now and all I can say is, don't take any other caffeine while on it, coffee, soda, nothing. First day I had really bad reaction to it, stomach ache, rapid heart rate, flushing skin, once I stopped drinking coffee and any other forms of caffeine I was fine. Does the product work? Idk, it curbs my appetite but its hard to tell if I'm losing weight. Its like all the other products out there, there isn't a miracle pill that gives you ripped abs without any effort. Any of us that are serious about working out and take diet and weight supplements know there's side effects and you just have to decide if there worth the results.

Great for energy, but at what cost?
I have used both the blue and the black and prefer the blue purely because of the side effects. I've never felt so nauseous in my life and never experienced this "niacin flush" before with another product, but I can tell you now it's not fun! Your Skin feels like it's on fire like I'm covered in acid! It doesn't happen every time I take it but I've been on the black for about 3 weeks now and have experienced the burn probably 4 times during that period. But other than that it definitely does what it claims to do.

Too much
I've taken the black three times now. The two times I've taken two I've been extremely jittery and tonight I've been questioning going to the E.R because I feel like I'm having a heart attack. I just did my blood pressure it was 159 over 91. I'm flushing my system with water to see if I calm down any but I definitely recommend not taking these if you are stimulant sensitive or have any concerns about your heart health. The time I took one I felt fine.

Gloria's Review
Day 1 : I took my first two gel caps 15 min. Before lunch ! I am a teacher, and after school, I work at a day care ! I felt like I had more energy, my mood was calmer, more fun ! The day went by smooth and easy !
I have taken Adipex in the past, and so far this seems to have the same effects ! I am looking forward to getting up tomorrow, and trying it again !
My mind seemed more alert, my energy was better than usual !

thought I needed an ER visit
I started these pills today. Almost immediately after taking the recommended dosage, my stomach started hurting and burning. Not only that my face and then the rest of my body became inflamed itchy and broke out in hives. I had to take a benadryl to counteract the effects. I dont think this is a safe pill for anyone. I have taken several other supplements and never experienced a reaction such as this.

Got the "burn"
I am 47, still work out about three times a week, and I have been taking this for about a month now (at most three per day) and find it's great for energy and does suppress my appetite. However, on occasion (not every time I take it) I do get a tingling that rapidly escalates into a burning sensation on the skin of my arms, face, and neck that fees like I have just been sunburned. My face and ears also throb. It fades away within about 15 minutes, and I never get an accelerated heart rate. I like the product and find it effective enough, but no better or worse than similar products on the market, except I never experienced that peculiar sensation with any other product. I read another review about high BP and rapid heart rate and am just wondering could it have been a panic attack brought on by this unusual feeling. I sit down and calmly wait it out, although the first time it was a little scary. And DO NOT take if you are sensitive to caffeine (I'm not, apparently.)

MAJOR HEADACHE
I took the recommended dosage(2capsules 15 minutes before a main meal) of Zantrex Black for the first time on Friday august 7th and initially felt great. the effect was powerful & I ate a meal followed a little later by a workout which consists of some push ups and stomach crunches.Even after my workout, when it was time to sleep, I couldn't. I tossed & turned until about 3am only to jerk awake at 6am to experience my heart beating rapidly accompanied with the most painful major headache I've ever had in my life.
Its a good thing I'm on vacation from work because there was no way I would be able to focus with such brain pain.The headache lasted for two days and when it was over I was very thankful. I don't see myself taking Zantrex Black again because of the headache. It is a powerful aid and definitely helped me get a better workout but its not worth the sleepless nights and the very painful headache. Never got hot flashes, though.

Lower dose
Day 1 was great, but Day 2, I had the Mother of all Hot Flashes, about 20 min. After I took two pills ! My coworker wanted to call the school nurse or 911 ! My face was beet red, felt like I was on fire ! Tomorrow, I will take one in the morning, and one before lunch !

Abdominal Cramps
I took 2 softgels with 12oz of water. I ate about 15mins later. Within 10mins of completing my meal I was toppled over in pain. My face and neck were both flushed. I drank two 16oz bottles of water but still felt like I was on fire. I broke out in hives. My stomach still and kidneys still hurt two days later. I returned the product to the the store.

Zantrex
i bought zantrex black. The first day I took it everything was ok. But the second day I drank coffee and then took the pill, bad idea. My face started to get hot and red as well as my chest. Felt nauseous and very dizzy., stomach started hurting I should have known better but I didn't think. I like the pill but not the side effects the stomach and nausea effects. The feeling is very uncomfortable. I want to loose weight but not at this cost. But every pill has a cost unless you just excercise and eat right. I'll run with it a few more days, but if it the stomach pains continue I will stop taking them.

Just starting
Ive been taking this for a week now, the very first day I experienced the red itchy burning body rash which scared me but I thought it was due to me having alot of caffeine before the pills. I take 2 at once 1 time a day with alot of water and small meal. Gives me a little energy, Im used to high caffeine. I feel fine the rest of the week hoping to see some results. Slightly lowers appetite.

Thumbs up
I started taking Zantrex 3 Black four days ago, and already lost 3 pounds. I watch what I eat and drink plenty of water. Where I work, I need an extra kick of energy to help me last through the day. I cut down on my caffeine intake so I don't have to worry about the jitters. I kept taking just one pill a day for right now. Yesterday, I tried taking 2 pills before lunch time and got the 'Niacin Flush' and didn't like it. I drank a lot of water, and this finally went away after 20 minutes or so. I like the idea I am losing weight, and will continue to take the pill. I will just be taking one pill a day.
Suzanna's Review
I took Zantrex black. On a 1-10 scale, I would rate it a 0. It's expensive. There are no results after participating in the full program. There is not even a caffeine rush! The program was done in conjunction with a diet and exercise regimen. The pills are huge and black. They are horse pills.
Happy with results!
I am 57 years old and have low blood pressure and am in good health. Since 50, I have not been able to get my weight down and can't eat any less or exercise any more. I tried Xantrex and went from 132 to 129 in one day without diet or exercise. I felt fantastic and appreciated the energy boost. I don't expect to keep that weight loss up each day but even a little help is a gift from God if you, like me, are in good health and don't have the blood pressure issues that some of these other ratings have. I can also see someone who is much younger getting shakes from the caffeine as I would have done in my 20s. However, as I said, at 57, this product is a blessing. Hope this helps.
not bad
I took 2 pills and thought I was having a heart attack. My face was on fire, had heart burn..but when I ate my normal chicken salad that I eat everyday, I could only eat half....so that's that. Not good, but not bad.

I started taking the black pill, for about a week. The burning stomach ache is horrible, it last about a min or so. I have no jitters, my appetite has suppressed a bit. no weight loss yet, the head ache is tremendous, I’m not buying this product again.

HORRIBLE
I was HOSPITALIZED because of this. I almost died. In telling you from someone who's use to nicotine and caffine I've never in my entire life been so scared. My heart could have exploded. Please do not take it. I do not wish anything even on my worst enemy to go through what I did. It was terrifying. And begging for God just to keep you alive. Should tell you something.

Is blackish stool normal for this supplement? I am feeling great having taken it for a week now. I am Noticing more energy and less hunger. I am only taking two a day with lots of water. I don't recommend coffee at all. If I could start again I would start with one softgel a day to see how I was affected. Luckily I havent had any adverse affects as others have.

Billy nocera's Review
It made my “load” huge. Also it used to dribble out. But after using black, I shot it onto my wife’s face when I expected to drop a small amount into her belly button as usual. She accused me of doing this on purpose. So it kind of had a positive and negative effect on my marital relationship all at the same time. Has anyone else experienced this? I am surprised they market this for weight loss. They should market it for its other effects. Just be aware that what happened to me may happen to you too. Just be prepared so you manage these effects in a positive way.

Zantrex pills are very strong. Try taking one pill at a time instead of two, and make sure you drink plenty of water. If you still feel nauseous, you should discontinue use.- Rob

Cut your dose in half, take it with a meal, and make sure you continue to drink plenty of water. If that doesn't change things, you may have to switch to something with fewer stimulants.- Rob

I made the mistakYe of taking 2 around noon then another 2 at 6pm. It's now the next morning and I feel like I'm tripping out. My pupils are super small, I'm dizzy, nauseous, spacey, almost a hangover/very drunk like feeling making even water difficult to swallow without it trying to come back up. I slept almost not at all and had the worst heartburn last night. I've had niacin before and most all of these other ingredients. When does this drugged sick feeling go away? I only took 1 this morning thinking it might help balance what I'm feeling. -Jennifer
When you're feeling like this, discontinue use, drink plenty of water (as much as you can) and get as much rest as you can. Once you're feeling better, after a couple days, try just one pill and see how you handle it. If that works for you, stick with the one pill at a time. If not, I don't know what ingredient is causing it, but I'd say Zantrex Black isn't for you.- Rob

Don’t take this too late in the day!!
Yeah, I’m not surprised. There’s a lot of caffeine.
I wouldn’t take it after early to mid afternoon if I were you. Let me know how it works out.
I eat 2 small meals a day and work out atleast 5 days a week for over an hour each day.
I think what’s happening is your stalling your weight loss by eating so little and only eating 2 times a day. I know the traditional weight loss advice is eat less calories then you burn, but what ends up happening is your body goes into starvation mode when you feed it less calories then it is used to.
The end result is your body shuts down your metabolism, and starts storing those calories as fat.
I would suggest you eat more meals (like 4 – 5 a day) and space them out about 2 – 3 hours apart. This will keep your body fueled and will keep your metabolism up.
Supplements wise, you may want to check out a fat burner called Phen 375. Phen 375 works well to burn that stubborn body fat that just won’t go away, here’s my review: https://www.supplementcritique.com/phen-375-review/

But my question is, does anyone know that when taking time released product like this, follow directions. When taking a fat burner like this?
I mean come on! The guy who took this product who gave it 1 star, probably didn’t build a tolarance for the product.
Rule of thumb,build a tolerance for it. Like Hydroxycut Black.
For 1-3 day take 1pill 2-3X’s a day, on day 4 take 2pills twice a day with meal or when you need energy. Do not exceed. 6pills in a 24hr period.
I use the same method taking Zantrex Black. And I’m reciting this off the top of my head.
As long as you build a tolerance to the fat burner you’ll be fine. And if you’re used to drinking caffeine.
But Zantrex should put in detail how to use it to build a tolerance for their product. So nobody won’t go to the ER for not following directions!
I am struggling with the last 10 so going to switch it up!
Will update in about a week!!
Black pill! Hope this black “magic” works for me, I’m only starting out this pm with 1 pill.
Will stay with 1 pill 3x a day and let’s hope I can repost later with my results!!
Skin flushing is a known side effect from Zantrex Black. It’s caused by niacin, and it’s characterized by red, hot skin.
Other than that, I haven’t heard of it causing a rash.

So how long do i have to wait to start these because im actually still taking the blue ones, my friend told me thari need to stop for a few days to get everything out my system.
How strong are these as free as caffeine people were telling me that i will be bouncing off the walls.
Will these help burn fat and help me lose weight
There’s no set time frame, but giving it a week in between should start you off with a clean slate. It’s got a whole lot of caffeine, but they don’t reveal how much.
Definitely don’t take them if you want to go to sleep any time soon, and watch your additional caffeine intake. These will burn fat, give you energy, and suppress your appetite.

WATER is what you need to not have got flashes rashes and shakes
I hope you’re feeling better by now. Zantrex Black has a lot of caffeine as well as niacin.
You could be reacting to either or both.
Rob

If you dont, it will cramp you up and you wont feel good.
How do I do this?
Sounds like you inadvertently signed up for a monthly subcription when ordering a free trial. They mention the subscriptin in the terms and conditions, but you usually have to work pretty hard to find it.
What you have to do now is call the company you ordered from and tell them to cancel your subscription. Otherwise, you’ll continue to be charged each month.

The doctor said it was too much caffeine in my body. My question is if i followed directions why was i feeling like i was about to die…
Sorry to hear about what happened. You may be overly sensitive to caffeine.
Whenever I start a new supplement, I start with a low dose, often half, for that exact reason.

I would like to let people know these pills are huge so if you have hard time swallowing pills this may not be for you. It’s the biggest pill I gave ever taken. The next biggest would be 800mg Ibuprofen and it’s not as big as Zantrex

There’s nothing on the label to indicate that you can’t.

I’m not sure what’s causing it, but stop taking it and see if it goes away. If you want to try again after a few days, lower the dose and make sure you take it with food.

That’s strange that it didn’t happen until 6 weeks in. I wonder if there was an interaction with something else you took.
Rob

I asked him about it and this is what he told me. Take a children’s aspirin about 20-30 mins before taking the niacin and I shouldn’t experience the side effects of taking so much vitamin B.
Sure enough, I had taken a low dose children’s aspirin beforehand and didn’t break out with the rash associated with taking “no flush” vitamin B. Like I said before, my doc is the one that gave me this little tidbit so try it on your own if you want.
Thx! Frank White, Albuquerque

Weight loss supplements are tough to quantify. One will work well for some people, while not at all for others. It sounds like this one may actually be working. Have you checked your calories intake vs output. It’s very important that you use diet and exercise to strike the right balance. You can use our calorie calculator to help figure out how much you should be eating.

Well if you’re eating 600 calories more than you’re using, you’ll gain weight. Though your body should be using more than 600 calories just living life. I suggest you sign up for my free “weight loss” ebook. It lays out a great plan you can use to lose the weight you want.

It really depends on a lot of things, but probably when you wake up tomorrow, you’ll be fine. Stick with just the one pill, and if you still don’t feel right, you should discontinue use.
Rob
SupplementCritique.com
Any suggestions?
It’s unusual to have absolutely no effect, so it sounds like Zantrex Black just isn’t for you. It happens. Sometimes, a supplement that works well for almost everybody just doesn’t work for you. Sounds like it’s time for a change. Try Instant Knockout instead.

I haven’t been able to go to the gym for almost two months! I had personal stuff going on where I had to eat out a lot and gained weight.
I am hoping I can take this pill until I can get to my goal weight and get my body back on track. I’ll keep you posted on results within the week and month.
With fat burning and weight loss; what does the Zantrex black do to your body? Will it burn the fat and tighten/tone those areas?
I really want to loose the fat in my stomach, thighs, and bottom; I didn’t know if this will help shrink those areas as it burns the fat and looses the weight.
Thank you, Ill keep you posted how it goes.
As a fat burner, it increases your metabolism, encouraging your body to use stored fat for energy. It also decreases your appetite.
But it doesn’t do anything to tighten or tone your body. You’ll have to do some exercise for that.
Looking forward to hearing how it goes.

I have a question for you, I tried the red bottle at first at the end of 2011 which was effective but a bit crazy so I switched the blue bottle and have been taking it for the last 3.5 years, had excellent results – within the first year I had lost 10/12 pounds, I went from 142 to 129 and kept it off for over two years. I started getting a little bigger last summer so I switched to the black bottle briefly when it came out but found it made me hungrier – I might give it another go and see if I have a better time with it
Basically I’ve gained all the weight I lost back in the last 8 months!!
Can you recommend something for me that is similar or more effective than zantrex?
I think the blue bottle has run its course and has stopped working for me as my body has become used to it. It used to be so effective for me and I would lose weight or maintain just by eating healthy and taking the blue bottle.
I didn’t need to do extra exercise.
Can you suggest a zantrex product or even another product that it going to make a difference when I am so accustomed to supplements now?
Thanks
Developing a tolerance is pretty typical with supplements. Sometimes all you need is a short break, but you could need more. Go with Instant Knockout. It’s a great fat burner/appetite suppressant. It also provides energy, which is good because you probably should add some exercise to your routine for better results. If it works for you, stick with it a while, then try the Blue Bottle again and see if it works again.
Rob

Thanks
No, not at all. It’s a fat burner, so it’s for weight loss.
It doesn’t have any ingredients that will bulk you up.
Rob
SupplementCritique.com
Btw im takong 4 a day with my meals
What I’ve found with fat burners is that if they don’t work by the first few days, they probably won’t. I wouldn’t worry, it happens. Not every supplement works for everybody. Check out Instant Knockout. It’s my number one pick.

How long does this last? I’ve taken the red pill b4 and I liked that much better.
Black pill is horrible
The effects probably shouldn’t last as long as they have. If you don’t feel better by tomorrow, you might want to consult your doctor.
Rob

Yeah, I adjust my dosing and timing pretty often. It’s good to pay attention to how your body responds and to be wiling to make changes when necessary.

I have noticed the weight lose already so it is working. And I am not nauseated.
Glad to hear it!

That screams screams sponsored to me. Also, how can you give a good review to a product that doesn’t give the exact amount of any ingredients especially caffeine also Ilst 75 pounds with NO fat burners or pre workout crap.
I’m at a lower weight now and, being this industry is so dirty I am testing stuff out on my own. BSN I will be doing.
This product that u claim is great is filled with crud. Let’s keep it real here.
There are different names but they equal one word caffeine. Also when u stop it u will gain all what little weight you lost.
PEOPLE LISTEN TO ME PLEASE I TAKE THIS TO HEART AND CARE YOU DO NOT NEED THIS TO LOOSE WEIGHT
It doesn’t sound like you’ve read this review or many of the hundreds of reviews on this website. I don’t claim that Zantrex Black is great.
I rated it as average and recommend that because of the large dose of caffeine, it should only be used short terms.
Rob

However I have seen a both positive and negative effect I do not know which way to go. I bought the black.
Yeah, niacin will make you flushed, but it shouldn’t last very long. The blue is definitely the one with the least side effects.
Rob

My husband got this for me and i can now after one month of taking them get back into jeans my thighs wouldnt let me in before. Im loving them and will continue until i reach my desired size.
I will keep you posted.
In all ive lost 48 lbs and am looking forward to dropping another 40 or 50 lbs. This is a great product when used correctly.
Still don’t know if I will be able to handle it !!!!!!
So I must be different from everyone else, I do get the upset stomach but it keeps me from eating, so its ok .
I’ve been taking Blue off and on as I work nights and it’s amazing at keeping the energy up and munching on food down.
So far, the Black has been great as I love the quick energy hit that i get from it. I take it at 6pm when I get up and then again at 12:30am when I take a quick lunch.
This burst of energy helps me stay focused and awake until I’m done at 6am. I still have enough energy for a quick run or bike ride in the morning and then I sleep great when I head to bed around 10am.
The downside is the occasional jitters.
I love my coffee and I’ve switched over to Decaf so that I don’t overload my heart.
I would consider switching back to Blue when I’m done with this bottle of Black, but I haven’t quite decided yet. About 40 pills left to go.
When I finished the red I started the blue pill. My ABSOLUTE FAVORITE!! I call it my mega super happy pill!! If u want sunshine and rainbows laces with unicorns: blue bottle is for u!
Lots of high energy, little to no jitter, no headaches, still suppresses appetite and no hard crashes. This is my go to pill for long days at work.
Even with just under 5 hours if sleep still makes happy!! Love the blue pill. Now zantrex black is a little different.
It gives me energy but it’s a mellow energy. I don’t feel like I wanna blow up the world nor do I feel like I’ve been swimming in glitter while in a tutu.
It’s just mellow. Lots of jitters tho IF u take it with caffeine like I do.
I like it but the blue bottle is by far my favorite and after the black i will definitely go back to the blue bottle!! LOVE the blue bottle!!!!!
