What is Pruvit Keto OS?

pruvit reviews keto os 2021

Pruvit is a world leader in ketone technology and ketosis supplementation. The Keto OS supplements are amongst their most popular products.

It stands for "Ketone Operating System". It is an exogenous drink available in a variety of delicious flavors.

You can buy Keto OS in bulk containers or smaller, more portable packets. It comes as a powder that is best dissolved in water. Drink one to two times per day, going for larger doses if you want to optimise cognitive and physical performance (more on this later.)

What are Ketones?

Ketones are compounds produced in the human body. They are used as an alternative energy source when blood sugar in the form of glucose is unavailable in adequate quantities. Thus, when you are carb depleted - and therefore low on glucose - ketones can take over.

The most common situations when this is the case, when ketones need to take over as an energy source because of glucose depletion, include periods of prolonged fasting or even starvation, or during a ketogenic diet designed specifically to manipulate these bodily mechanisms.

At these times, your body will enter a metabolic state known as ketosis: when the liver converts fatty acids into ketones (a process called ketogenesis) which you then use as energy. Your body will be very efficient at burning fat for energy at this point, hence the ketogenic diet’s popularity for weight loss.

When your body is low on glucose and blood sugar is unavailable in adequate quantities, these ketones will become your main energy source. They are used efficiently by brain and muscle tissue, which are able to effectively break them down.

Because of their use by the brain, ketones are touted as great for boosting cognitive function. This is one of the main reasons that Pruvit has become so popular.

What are the Benefits of Pruvit Keto OS?

lose the stubborn belly fats

Pruvit Keto OS is ideal for people who don’t like to wait: Pruvit claim that their supplements bring about a state of ketosis within an hour of consumption.

If you want to try the ketogenic diet but have been dissuaded by tales of hard work, dedication and strict nutritional protocols, and if you don’t want to wait weeks for ketosis to take effect, they have the answer for you.

There is a great deal of truth to the stringency involved in a typical ketogenic diet. You would usually make up only around five percent of your diet from carbs, a further fifteen percent from protein, and a massive eighty percent from fat.

This is hard to begin, hard to follow, and leaves you with very few options for variety and affordability.

Exogenous ketone supplements like Pruvit’s were designed to overcome this. They give you a bit of a shortcut to ketosis, giving you the intended benefits of increased ketone levels without putting you into a strict carb-depleted state.

There is an immediacy to the ketone levels when using these supplements: traditional ketogenic diets bring about a slow rise, during which time the hunger pangs, nausea and energy drops can be awful, whilst exogenous supplements give you a rapid rise.

After ingestion, beta-hydroxybutyrate is absorbed quickly and immediately converted into energy for your body to use.

This rise in ketones can be met without a state of ketosis being necessary, though a ketogenic or near-ketogenic diet may maximise their efficiency.

All in all, exogenous keto supplements like Pruvit’s Keto OS may give you the following benefits:

  • Weight loss
  • Increased energy
  • Improved cognitive function
  • Improved mood
  • Enhanced athletic performance

Key Ingredients of Pruvit Keto OS

key ingredients

Pruvit Keto OS is largely gluten- and dairy free, with itsmain ingredients including:


L-Taurine is an amino acid whose functions include a significant role in protein synthesis and muscle growth. This is incredibly useful for maintaining strength and mass during a deficit.

Fermented L-Leucine

This is an essential amino acid, meaning the body cannot produce it. It must be taken in through dietary sources. As L-Taurine, it aids muscle growth and maintenance.

R-Beta Hydroxybutyrate

R-Beta Hydroxybutyrate is important for controlling blood ketone levels. The Keto NAT formula in particular contains a very bioavailable form of R-Beta Hydroxybutyrate which will aid in appetite suppression, increased energy and improved athletic performance.

C-Med 100

C-Med 100 is the Inner Bark of Uncaria Tomentosa and is the trade name for AC-11 DNA repair. It will help your body support rapid repair, recovery and growth post-workout. It will also support healthy cell function, cell debris removal, and aid in cell longevity.

Other ingredients in Pruvit’s products include:

  • Rebaudioside A (Stevia Extract)
  • Erythritol
  • Caffeine (charged version only)
  • Citric acid
  • Vitamin B6 (as pyridoxine)
  • Vitamin B12 (as methylcobalamin)
  • Natural flavour
  • Xanthan gum
  • Beta carotene
  • Vegetable juice color

What Are the Different Flavors and Taste?

flavors and taste

Each of Pruvit’s products comes with a few different flavors, which I’ve detailed below, alongside brief descriptions:

Chocolate Swirl

this is lovely, genuinely tastes of rich, creamy chocolate, and is a real treat. I like it mixed in with black coffee or cream.

Orange Dream

this tastes a bit like chocolate orange and is definitely on the sweeter side. If you like your sugar, it’s great, though otherwise you may need to dilute it a little.


Summery and tropical, this tastes like a mixture of pineapple and perhaps mango? Either way, it tastes great and is very refreshing when mixed with cold water and a bit of ice.

Raspberry Lemonade

Another refreshing one, this gives you a really natural tasting lemony zing. It really cleanses the palate as it does its good work.

Swiss Cacao

Another chocolatey one, Swiss Cacao does definitely invoke the creamy alpine chocolate that drives people nuts. Very nice.

Maui Punch

This is fruity and nice, like the punch that lends it its name. This one is particularly good with hot water.

Pina Colada

Coconut and pineapple, reminiscent of lazy days on hot beaches… what’s not to love?

Pruvit Results: Before and After

There's no denying after all people that has been successful after using Pruvit on their daily regimen. It's been proven effective and tested by a lot of users.

Pruvit Reboot

  • Provides you with all the right nutrients for the diet
  • Feel full for longer period of time
  • Helps alleviate side effects
  • Complete kit for ketogenic diet

It’s very hard to stay in ketosis, to stick to a ketogenic diet. It’s impractical, can be expensive, and it’s monotonous and unsatisfying at times. Beginning ketosis always puts you into a poor state - keto flu is very real - and energy levels are a great issue for the first couple of weeks.

Therefore, I was pleasantly surprised by how well Pruvit Keto OS worked. It gave me the benefits I have looked for on ketogenic diets whilst being easy to manage and maintain. I can say with confidence that my ketone levels increased. Combined with moderately low carbs and high protein levels, Pruvit gave me a great energy boost that lasted quite consistently throughout the day, beginning within an hour of my first drink. With this came a quite astounding uptick in my athletic performance. Of course, you expect any ketogenic product to help with day-to-day energy levels and boost your metabolic rate. However, my workouts also took a great deal of benefit from Pruvit Keto OS.

keto os before and after

It's overwhelming that almost all users has positive pruvit reviews.

I lift heavy weights and box. Suddenly, each workout became more enjoyable, my body felt freer and looser, and I was able to tap into previously unknown energy reserves. I was able to increase volume quite drastically and work the bag harder, for much longer.

My recovery also benefited. I was less tired immediately after each workout and woke up feeling far more refreshed in the morning following intense sessions. DOMS became less of an issue for me, with muscle aches and fatigue greatly decreased, and I was able to get back into the gym faster than ever.

Finally, I did feel that there was a small thermogenic (fat loss) boost when taking Pruvit. Within the first few days, I noticed my waistline shrinking down, and I had lost a couple of pounds by the end of my first week. Of course, this could have been due to the harder workouts I was able to put myself through much of the thermogenic element of the Keto OS itself - either way, the supplement helped me lose unwanted body fat, which was greatly appreciated.

Other People’s Weight Loss Results

pruvit result satisfied consumers

Looking at a host of other user testimonials, it seems that I’m not alone in experiencing these great benefits from Pruvit’s Keto OS.

Many users across the web have recorded their results, reactions and experiences using Pruvit’s products. Summing a lot of them up, it appears that people have been consistently impressed with the flavors on offer (Unleashed Blue Ocean pina colada seems a firm favourite), with the increased energy they have experienced on Pruvit’s supplements, and on the improved weight loss that they have brought about.

Better Focus. More Energy.

Of particular note are the recorded instances of people feeling incredibly focussed. We all get brain fog sometimes, especially when we are particularly busy or when we have had a tough workout. However, Pruvit users report that this brain fog disappears entirely when taking Keto OS.

Weighing themselves before and after - and taking pictures - has allowed many users to show the weight loss journey that Pruvit’s OS Max has brought about. Like me, they have found that several pounds are easy to shed in the first couple of weeks with few, or no, other changes to their diets or lifestyles. Slimmer waistlines are abundant, as are more toned physiques and more defined looking musculatures.

Summing Up All the Satisfied User's Feedback.

As a round-up of all the feedback I have seen from user reviews for Pruvit Keto OS, it seems fairly universal that customers have experienced the following main benefits:

  • Weight loss, especially in subcutaneous fatty tissue
  • Preservation of lean muscle mass, even in a caloric deficit
  • Gains in physical strength
  • Sustained, consistently raised energy levels
  • Improved cognitive function (and lack of brain fog) with increased focus
  • Better sleep and mood
  • Improved digestion

Does Pruvit Work?

Yes, Pruvit’s Keto OS works very well. Having tried it myself, I can testify to the abundant energy supply that it unlocks. It should do everything that a ketogenic diet does, including a very much reduced appetite, continually heightened energy levels and alertness, and a decent amount of fat loss.

Fasting becomes a lot more manageable on Pruvit supplement, so if you’re struggling with intermittent fasting, it will work well for you. You won’t have hunger pangs or energy crashes, and you won’t have the nasty brain fog that oscillating diets and eating protocols can bring about.

So to conclude if does Pruvit work? Yes for sure!

The flavors I have tried are all really nice as well, so it’s a pleasant experience taking Keto OS. They either actively taste good or are entirely unflavored and thus easily hidden in other drinks.

As for whether it’s worth it, I believe so. For the price tag, you get a well-flavored product that can bring about the following benefits:

  • Fat loss
  • Muscle preservation and strength gains
  • Improved energy, alertness and cognitive function
  • Elevated mood and better sleep

How to Use Pruvit Reboot Properly?

pruvit reboot

For best results, it’s advisable to take 2 helpings of Pruvit Reboot Keto OS per day, though some report that benefits can be felt with a single serving. Dissolve each packet with around 12-16 oz of water (usually cold, though some flavors work better hot) and mix.

Information from their website recommends taking a charged, caffeinated dose of Keto OS before 9am. This will support optimal performance throughout the day, with the caffeine giving you a handy pick-me-up. Drink plenty throughout the day, taking in around half an ounce per pound of bodyweight. This will help to keep you energised and will have multiple additional health benefits. Finally, take a decaffeinated dose of Keto OS around 7pm. This will improve your sleep quality, aid in your body’s repair, and allow you to wake up the following morning feeling nicely rejuvenated.

A ketogenic diet is not necessary when you’re taking Keto OS, as detailed above. However, best results will come with lowered carb intake and higher levels of fat and protein. Pruvit Reboot doesn't do all the work for you but you have to really stick to the diet principles also. Keep away from all the carbs and trust the Pruvit Reboot process.

Are there Any Side Effects?

To those who doesn’t know, keto diet may not be for everyone. For some, they have to consult their physicians first before taking any action towards this diet. On top of that, you have to be on point on your food proportions in order to get results. Now, Pruvit supplement products is made to help you get into ketosis faster and to stay on that state longer.

So are there any side effects on taking pruvit supplements? The answer is none. These supplements undergone a series of research and tests to be proven safe to take and to have no signs of side effects. So why are people telling that they feel sick after taking? Let me take you back from what I first said, Keto diet is not for everyone.

Now if you feel something weird after taking supplements for ketogenic diet, then maybe you are not suitable for this diet. This maybe a good time to take a check on your health and ask your physician on how can you take the diet safely without any complications. Don’t lose hope on losing weight because there is always a way.

How Does it Compare to Perfect Keto?

how does it compare to others

So, which product would win in a fight between Pruvit Keto and their nearest competitor, Perfect Keto?

It depends on a couple of things. Whilst Perfect Keto is a solid product, known and trusted by many and able to deliver what it promises, generally speaking I would say that Pruvit OS is superior.

I’ve got a couple of reasons for this. First off is the flavor: the range of products and flavors that Pruvit deliver, and the quality of each one, means that there is something for everyone. Whether you prefer fruit or chocolate, exotic or comforting, they will have a powder for you. And the quality really is good.

My second reason is performance-based. Though Perfect Keto has fewer carbs and calories, I found a better result from Pruvit Keto. The thermogenesis was slightly better, the energy gain was a lot better, and the mental alacrity was without equal.

However, Pruvit Keto OS is a lot more expensive. Though they are slightly inferior, Perfect Keto do give broadly similar, still good results, for less money. It’s a bit of a toss-up for sure, but if you are able and willing to spare the extra cash, I would urge you to go with Pruvit.

If you still can't decide where to go, then we recommend you this great alternative.

Ketosis Advanced

Great Alternative to lose weight and achieve Ketosis faster. 

Boost Energy and Enhances Cognitive Performance.

The Pros and Cons

This being said, let’s weigh up the pros and cons of Pruvit Keto OS. As with any product, there are some trade-offs, some pluses and minuses:


  • Great bioavailability
  • Free from dairy and gluten in most flavours
  • Contains C-Med
  • High-quality ingredients in a proprietary blend
  • Natural fermentation process
  • A string of proven, worthwhile results


  • Expensive, especially compared to its competition
  • Most evidence is testimony, not clinical
  • High sodium levels and potential side effects have been noted
  • High amounts of unsaturated fat (OK on a keto diet, but not great) 

Where to Buy Pruvit Keto OS?

keto reboot

However, the company does offer up to 90 days to return the product if you’re not satisfied with it and will provide you with a full refund.
