Prüvit Keto OS Review

We decided to write a Pruvit Keto OS review since ketones and the ketogenic diet have become such a popular way to lose body fat.

You’ve probably heard of “being in the state of ketosis” which is when your body is burning fat for fuel instead of glucose (sugar/carbs).

Or, maybe you’ve heard of the Ketogenic diet which is the high fat/low carb diet used in medicine to put your body into ketosis.

But not everyone wants to adhere to a strict diet, and that’s where a supplement can help.

There is a new supplement on the market called Keto OS that is all the buzz right now and we recently had the chance to test it out.

Keto OS is a ketone supplement powder that gives you the benefits of ketosis without having to be in nutritional ketosis. I have to say, our results have been remarkable. 

So what is it about this supplement that can put you into fat burning mode without having to adhere to a strict diet?

What is Prüvit KETO OS?

Prüvit’s KETO//OS (Ketone Operating System) is a proprietary, exogenous ketone delivery drink that is the first of its kind which can bio-hack your body into ketosis in under an hour.

Normally, ketones are only produced during times of prolonged fasting (or adhering to a strict ketogenic diet) which is why the average person has probably never experienced ketosis.

Let’s face it, the average American never has to experience famine and most of us eat a high-carb, high-sugar diet.

We’re all sugar burners when we were designed to be FAT BURNERS!

So let’s talk about ketones and why they are an ideal choice to fuel the body with more power and melt fat in this Keto OS review. 

With 38% more energy than glucose, ketones are an ideal energy source, and can provide many health benefits such as:

• fat loss
  
• increased energy
• feel more focused, reduced brain fog
  
• suppressed appetite
• better mood
• better sleep
  
• improved digestion
  
• muscle preservation

Keto OS’s formula is a powder that you mix with water and drink up to twice per day. It contains a specifically engineered formulation of ketone mineral salts (BHB, betahydroxybutyrate) for high energy fuel.

It comes in two formulas: the “Charged” version, which contains about the same amount of caffeine as you’d find in a cup of coffee, and decaf.

I can’t think of another fat burner that you can take that’s decaf so literally anyone can benefit from this drink (kids, and pregnant or nursing moms included–decaf of course).

The long of the short is, drinking Keto OS puts your body into ketosis in under an hour without having to restrict your diet!

For optimal results, you should follow a sensible diet such as Paleo or Ketogenic Diet, or simply a low carb diet. It’s also beneficial to follow a good exercise routine, but it’s not necessary to experience results, as Katie demonstrates below in her Keto OS review.

Our Personal Results With KETO OS

Katie took Keto OS for just under three weeks and lost 12 lbs!

As you can see from her before and after pictures, her chin is more defined, the fat underneath her arms diminished, her belly is leaner, her waist got freakin’ tiny, and her legs and butt got noticeably smaller and tighter!

Katie also practices yoga to keep fit, but taking the Keto OS really pushed her into a whole new level of fat burning and she had a noticeable increase in energy, strength, and personal drive.

Katie’s Testimonial Using KETO OS

I’m so excited to share with everyone my journey using Keto OS!

It’s been extremely hard for me to lose fat over the years, which has been very frustrating and I struggle with energy.

Back in 2015, a friend of mine who knew what I’d been going through introduced me to this product. I cannot thank her enough!

When she mentioned “ketosis,” my antennas went off, since I’m familiar with the ketogenic diet,  and the results have been mind blowing! 

In just 3 weeks drinking ketones I  managed to lose 12 lbs of fat, and tighten up in every part of my body.

Not only have I lost body fat, but the product has made my yoga practice so much stronger and given me so much motivation!

I practice yoga  2-3 times a week now with much more focus, intensity, and strength. I never had the dedication or the energy before like I do now.

I take the “Charged” KETO OS in the morning, and sometimes later in the afternoon depending on my day. I also use the MCT//143 in my coffee each day!

I started out by taking only a half a packet a day of the Orange Dream for about 3 days to let my body get used to it. I had a slight upset tummy the first day but it didn’t last.

I drink mine with ice and water, and usually add lemon. Shake shake shake!

When I first started the only flavor they had was Orange Dream, but Pruvit has advanced over the years with formulas and flavors!

Now I LOVE the new Heart Tart!

It was recommended to me to follow a Ketogenic diet as well as using the product. However, I’ve found that I don’t need to follow a strict diet. 3 weeks and these results!

I do however try to maintain a mostly clean, lower carb diet. I cut soda, cut out too much bread, and cut a bit of alcohol as well. Overall, I would never regret the choice that I made in buying this product and continue to drink it 3 years later.

It was a little pricey at first but so worth it! I do the Smartship for 22% off my ketones each month and I love sharing this magical drink with others!

Keto OS Review of Flavors

Keto OS Orange Dream Version 2.1

Pruvit’s Orange Dream contains a unique formula, including exegeneous ketones (BHB) mixed in an MCT oil blend extracted from coconuts.

The Orange has always been a big hit, because MCT can reduce appetite and aid in fat loss. MCT is also great for the brain and memory.

As Katie stated, the Orange Dream tastes like a creamscicle. It’s great thrown in a blender with water and ice!

Keto OS Chocolate Swirl Version 3.0

Pruvit recently released its new 3.0 edition of Keto OS – Chocolate Swirl! And with it comes a new and improved formula.

If you’re a chocolate lover, you’re going to love how this tastes – just like a tootsie roll. So What’s different about the formula?

• Vegan, Dairy and Gluten Free so now there’s a product suitable for everyone.
• Ratio of BHB salts optimized creating sustained ketone levels throughout the day
• Ketogenic Amino Acids and Short Chained Fatty Acids were added, which use the same transporters as ketones making for quicker delivery into the system
• Added a Prebiotic – helps with digestion

Keto Max Maui Punch

Pruvit’s first Max product, and one of their most popular flavors, is the Keto Max Maui Punch, which tastes just like Hawaiian Punch!

The Max products pack the highest punch delivering the most pure and most bioavailable levels of ketones into the blood – 40% stronger than the Keto OS with a quicker uptake.

Keto Max BHB’s Max salts are exclusive to Pruvit, and are bioidentical to the ketone bodies your liver produces when in nutritional  ketosis.

Pruvit continually strives to improve their formulas, and the new Max formulas also contain coveted AC-11 for DNA repair.

The Max formulas are great as a preworkout supplement providing sustained energy, better fat burn, and quicker muscle recovery.

It also has a lighter flavor since it does not contain MCT oils like the Orange.

Bio Max is gluten free, dairy free, and Kosher certified and is offered in both charged and non-charged versions.

Keto Max Swiss Cacao

Pruvit’s Keto Max Swiss Cacao is made with real cocoa, and tastes like iced hot chocolate.

Swiss Cacao has the same “Max” formula as the Keto Max Maui Punch, allowing for a quicker and greater absorption rate of the ketones while providing maximum energy and fat loss.

The Swiss Cacao is gluten free, dairy free, and kosher certified and comes in both charged and decaf.

If you’ve tried the Keto OS Chocolate Swirl and it’s not chocolatey enough for you, you will love the Swiss Cacao!

Keto Max Raspberry Lemonade

Keto Max Raspberry Lemonade was released over the summer 2017 and has been a huge hit!

The Raspberry Lemonade tastes similar to country time lemonade and is as refreshing as it sounds! A perfect mix of sweet and tart!

The Raspberry Lemonade tastes delicious just mixed with water and ice, or mixed with a sparkling water like La Croix.

If there’s one thing Pruvit has done with precision it’s continuing to release flavors that consumers love the flavors of, which keeps them happily drinking ketones.

The Keto-OS Raspberry Lemonade  is gluten free, dairy free and kosher certified.

Keto Max Splash

The new Keto Max Splash is a light, citrusy fusion with hints of watermelon and grapfruit.

What’s different about it is that it contains AC-11 DNA repair and added Vitamins B3, B6 and B12. Awesome for energy and reverse aging.

But don’t worry, all the new Max formulas contain the coveted AC-11!

Keto Max Heart Tart

Keto Max Heart Tart was released on Valentine’s Day 2018 and we’ve never seen a quicker release to the permanent menu!

The fans loved it so much they practically forced Pruvit’s hand to produce more! Heart Tart has a light strawberry flavor and is easily chuggable.

As all the other Max formulas, it is gluten free, dairy free, and kosher certified, and contains the AC-11 for DNA repair.

Tip: mixing half Orange Dream and half Heart Tart tastes amazing, like sherbet! If you don’t like the Orange straight, it’s a great mixer flavor if you want the fat burning benefits of MCT.

Keto Kreme

Pruvit’s Keto Kreme is their fat coffee creamer and is a sure fire way to ramp up fat loss and great for intermittent fasting!

You mix it with your coffee or tea, and drink.

Keto Kreme has 12 grams of fat per serving and is made from MCT, coconut oil and four different patented collagen blends, DC-11 (anti-aging DNA repair) and sweetened with Stevia.

My wife loves Keto Kreme with Chai tea. She’s added it to her morning routine and it keeps her feeling full and aids in fat burning.

While the Keto Kreme doesn’t contain exogeneous ketones like all three of the Keto OS flavors, it will help to naturally increase ketone production in your liver and if you don’t know by now, fat burns fat!t

Blue Ocean Unleashed (Amped)

Pruvit’s new Blue Ocean Unleashed tastes like a pina colada!

Blue Ocean is the strongest ketones blend on the market, providing amped energy and appetite suppression.

It contains more caffeine and BHB (the ketone body) than Keto Max along with AC-11 DNA repair and provides fast and sustained energy. If you want the strongest ketones, go for the Blue!

Keto Reboot 60 Hour Fast

Pruvit’s new metabolic boss is the Keto Reboot, which is a kit with everything you need for a 60 hour fast.

The purpose of the Keto Reboot is to reset your diet, your metabolism, deplete all the glycogen from your body and get you into a deep fat burning state of ketosis.

The Keto Reboot kit contains Keto Max, Keto Kalm Teas, Better Broths (bone broths), and Signal-OS pills for DNA repair, there is no eating during the 60 hour reboot.

All the liquids contain high levels of BHB which suppress the appetite and keep you feeling energized.

We’re seeing great results with the reboot. If you have significant fat to lose (or even if you just need a quick ab shred), doing the reboot monthly and drinking daily ketones is a very effective method for fast results.

Is Keto OS Good for Men?

We didn’t want to leave the guys out of this Keto OS review! Ketones absolutely work just as well for men as it does for women.

My brother- in- law started drinking keto and lost 18 lbs in just 6 weeks – check out his results!

He’s a high level executive and it gives him energy to stay sharp and focused throughout the day.

He actually mixes the Maui Punch with the Orange Dream and makes what he calls “fruity pebbles.”

The MCT in the orange also fills him up, he has to drive a lot for work, so it keeps him satiated on those long trips and keeps him  energized and focused.

Guys, if you’re on a low carb diet and need energy for workouts, or help staying in ketosis or need to shed fat, this is a great product to try.

Having another serving on the way to the gym is going to give you a definite boost in energy, increase performance, and put you right into ketosis to burn fat while preserving muscle. 

Keto OS Review – Are There Any Side Effects?

As with any supplement, not everyone will have the same experience and we wanted to touch on that in this Keto OS review.

The recommendation is to start by drinking half of a packet of Keto OS per day for a couple days, to get used to it and adapt to the ketones.

The Charged version does have caffeine, so if you’re sensitive to caffeine you may want to opt for the caffeine free version, or only drink the Charged in the morning, otherwise it could have the potential to keep you up at night.

Some stomach upset can be normal but this should subside once you Keto adapt. If this happens to you, push through.

Where Can I buy KETO OS?

You can purchase Pruvit’s Keto OS online from their official website and it comes with a 100% 90 day money back guarantee.

Pruvit also has a good deal if you set up Smartship, you’ll get your ketones 22% off each month and cancel anytime or change flavors.

They have two versions of the drink powder, the On The Go (OTG) and Kan. The OTG is individual envelopes and the Kan is a container with a scoop.

Only the Keto OS Orange Dream and Chocolate Swirl come in a Kan, Max is all OTG.

They currently ship to the U.S., Canada, Australia and part of SE Asia.

Here are the current prices:

• 15 servings (OTG) = $85
• 20 servings (Max) = $130
• 30 servings (Kan) = $144
• 30 servings (OTG) = $160
• 60 servings (Kan 30 + OTG 30) = $300
• 90 servings – Family Pack (90  OTG Mix Pack, Orange Dream & Chocolate Swirl) = $408

ABOUT SMARTSHIP:  Smartship gives you a 22% off discount and will ship to you every 30 days, which is significant savings, and with no time commitment, we think this is the best deal.

When you sign up, it will show you your start date (30 days away). It’s easy to cancel, edit products and push out or push up the date. There is also no  commitment.

With that said, I recommend doing a “today and smartship” order so that you won’t be waiting for weeks to get your first shipment.

Recommendation

Keto OS has proven itself to be a fat burning, energy boosting supplement that REALLY does work on an outstanding level.

I’ve seen this stuff work for several of my immediate family members.

I would even classify it as one of the best female fat burners we’ve ever tested!

This product would be beneficial and is recommended for BOTH men and women.

And while Keto OS is pricey, there is no comparison when it comes to quality and tasty flavors that are enjoyable to drink, so we give Keto OS a big thumbs up!

We encourage you to check out the Keto OS website to learn more. They have a lot of videos, additional testimonials and very detailed information about the science behind this product.

I hope you enjoyed our Keto OS review!

User Questions and Answers

Is Keto OS better to drink before or after your workout? -Liz

Hi Liz, thanks for your question. Keto-OS is best for fat burning if you drink it first thing in the morning on an empty stomach. If you're a coffee drinker, drink your coffee, then drink some plain water, and then drink your full serving of Keto-OS. For best results, don't eat until you're hungry (you'll be burning fat for fuel). Depending on when you work out, you can definitely drink another serving before your workout for energy and focus. My wife usually mixes her afternoon keto serving in a water bottle and drinks it on the way to the gym, and sometimes sips on it throughout her workout. The recommended amount is up to two per day. There is a caffeine-free version if you work out after work and you don't want the caffeine to keep you up.- Rob

Does alcohol, such as scotch or red wine interfere with results from KETO// OS ? -Harvey

Wine can be tricky. Some people can have a couple glasses and stay in ketosis. Some can't. You're safer going with the scotch.- Rob

How long should it take once taking the Keto OS Max for my body to go into ketosis? I started on Sunday with one in the morning and Keto Kreme in my coffee. I IF as well and usually don't have anything to eat from 6:30 pm - 12:30 the next day at lunch. As of yet, I am not even tracing or have I lost any weight. Any suggestions? I look forward to your prompt response in this regard. -Nancy

Hi Nancy, to go into ketosis for up to 24 hours, the recommended dose is to drink two Keto OS per day. Sometimes it takes a little while for your body to adapt. The urine strips are also only so accurate and our ketones are lowest in the morning, so try testing at night. A blood test is the only method that is truly accurate. But I would keep testing this week and see if you start to trace. Also, start drinking two per day for optimal results. The IF is a great method, your weight should start budging soon. Remember to drink plenty of fresh water throughout the day (half of your weight in ounces in fresh water). Good luck! - Rob

I really want buy it but I want ask.Keto os can help me go to keto so fat.I'm on low carb diet but I worry I'm not into keto that why I can't lose my weight.give me answer to fat,please -Anna

Anna,  If you're already eating a low carb diet and you're having trouble getting into ketosis, this is where Keto OS can really help. It will put you in to ketosis for 24 hours if you drink two servings per day which is really going to help you burn more fat. It will also give you energy, focus and help with inflammation which can really be beneficial when it comes to workouts, and also just getting through the day while feeling better and having no energy slumps. Good luck!- Rob

Do you post to Australia and if so how much do you charge? Thank you -Morena

Morena, thanks for your question on Keto-OS. Unfortunately, right now it's only available for shipment in the U.S. They are very close to being able to ship internationally and we will be sure and update this review just as soon as we get more information. Keep in touch!- Rob
