Full Review


My name is Eric, now freelancer and traveler, and I am very excited to be sharing my Pruvit Keto//os journey with you in the form of this review article.

So, a while ago, I felt myself waking up grunting. Perhaps you are familiar with this grunt — it’s the one that comes after you resist the urge to throw your alarm clock across the room. I was as low energy as could be. On top of that, I was as heavy as could be.

I craved the motivation I saw in those superheros jogging on the street, in the rain, at 5 am. However, I couldn’t think straight enough to even think about putting on that sport outfit and jogging down the street — nonetheless at 5 am, and certainly not in the rain.

Fast forward to now: I wake up — without needing an alarm clock — excitedly thinking to myself, “YES! Yes! Yes! this is what I was looking for! 

Now, you may be wondering, “What the heck happened?

Well first, I got fed up with living the way I was living before. I was done. I set the plan to make a drastic change in my life.

As soon as I put my energy towards that, all signs pointed to the ketogenic diet. I thought it was super boldy to go from zero motivation to something as intense as this keto diet. However, as I set my mind to do it anyway (hooray!), I ordered a very special supplement. . . Can you guess?

Yes, Pruvit Keto//OS.

So, here’s a more in-depth look at what exactly this substance is, how it works, and what it did for me.

What is Pruvit Keto//OS?

“Ketone Operating System,” in case you were wondering what Keto OS stands for — and it certainly works like an operating system.

Pruvit Keto-OS is a scientifically-designed powdered fat-loss ketone drink that helps get you into a state of ketosis by way of exogenous ketones. The word “exogenous” means to be derived externally. So, by drinking Keto//OS, you can get into a state of ketosis much quicker (in 4-5 hours) and with far less effort than traditional, non-supplemented keto dieting. However, it’s important to note that you still have to put forth the effort; it’s a supplement, not a substitute.

To call this supplement a “powdered fat-loss ketone drink” is actually an understatement. If you are looking to not only greatly boost your body’s ability to burn fat, but to boost your athletic performance, your mental focus and clarity, your energy levels, your cells’ ability to regenerate, and much more, Keto//OS is your drink.

Pruvit, themselves, claim:

KETO//OS ® (Ketone Operating System) is a revolutionary drink mix based on a proprietary ketone energy technology. It delivers advanced macro nutritionals and promotes optimized cellular regeneration, energy and longevity.”

One of the coolest aspects of this company is that they have done little self-promoting. They have been able to promote so well due to their customers’ reviews. They don’t want to convince you, they want you to try it and Pruv-it yourself.

How does it work?

Your body has two different methods of generating energy: by way of glucose or ketones. It’s default (in our modern world) is to burn glucose. However, when your body experiences starvation or a restricted level of carbohydrates and an increase in healthy fats (A.K.A., the ketogenic diet), it begins to burn ketone bodies. Strangely, burning these ketone bodies works as a much more ideal energy source for both your body and your brain. This makes much more sense when you think back to a more paleolithic time period — where perhaps everyone was in a state of ketosis.

So, by ingesting these exogenous ketones, you can accelerate your state of ketosis. They allow you to have a bit more flexibility in what you eat, and can even help minimize the effects of the keto flu.

How to Use Pruvit Keto//OS Properly

One of my favorite things about Pruvit Keto//OS is how easy it was to incorporate into my life. All I had to do was follow these guidelines:
Begin steady. Start out with ½ a serving and work your way up as needed (this generally takes 3 days)

Take two servings a day. The first serving between 6 – 9 am and the second one from 1 – 4 pm

Drink loads of water. Ideally, drink between ½ – 1 ounce of water per pound of body weight.

Take electrolytes. At least 2-3 times a day.

Do your best. Do your absolute best to still follow a ketogenic diet; don’t worry, it gets easier as your body becomes super in love with it’s benefits.


The most notable benefits of Keto//OS I experienced, were as follows:


Suppresses food cravings/appetite

Heightens levels of energy

Enhances cognitive function

Encourages restful and optimal sleep

Fantastically improves mental, motor, and athletic performance and endurance

Stabilizes mood

Encourages a refreshing sense of wellbeing

If you are curious about the validity of these benefits, good! We should be always curious and skeptical; I know I sure was when I first started. As Pruvit is a highly professional and scientific company, they have definitely done their research and performed their clinical trials.

My Own Pruvit KETO//OS Review

As I mentioned in the introduction of this Keto Os review, I had completely had enough.

To admit, I’m not the most patient person. I wanted to see results, and I wanted to see them fast. I set my intention to find something that would supercharge the growth journey I was about to set sail on… I wanted a catalyst, of sorts.

That day, I ran into an old friend at the gas station. He looked incredible! Not only did he look incredible, but I could tell that he felt incredible. To be honest, I hardly recognized him. Without me even having to ask, he told me about his new keto lifestyle. I liked that he used the word lifestyle instead of diet — I wasn’t looking for just a change in food consumption. After hearing him passionately rave about all things keto, I was intrigued. I wasn’t quite hooked, though, until he told me that he started this new lifestyle only 4 months prior.

That much change in only 4 months?

He was also enthusiastic to mention Pruvit Keto OS exogenous ketones, he said they really helped him to jumpstart his ketosis.

After my interaction with him, this ketogenic lifestyle kept popping up everywhere! After spending hours researching the science behind this keto lifestyle, reading many Pruvit reviews, and learning more about these highly-touted exogenous ketones… I was on board. The above video in particular really helped me to understand the science behind how it all worked.

The first couple days of my new lifestyle were difficult; I had many lifelong habits to break.

How does it feel like?

So, after reading more Pruvit Keto//Os reviews, I decided to order the Keto//OS supplements… Boy oh boy, did I feel them right away (hence the writing of this article)! Taking the exogenous ketones really helped show me just what being in ketosis felt like.

Before knowing exactly what ketosis felt like, it was difficult for me to find the motivation to get into ketosis. However, after I got my first keto taste (thanks to Keto//OS), I was hooked.

I felt like a superhero.

I felt that how I was feeling shouldn’t be legal. I had to continuously ask myself, “Is this for real?” Even though I hadn’t dropped a pant size in a day, the way my mind was operating felt so pleasantly foreign. The energy and motivation I had in my body was awe-inspiring. My supremely and constantly sore knees felt like energetic springs. I also decided to go on a low-carb diet  and supplement with Pruvit Keto/os to achieve my desired results.  

Combining that with having my first taste of ketosis, I was positively on fire.

I didn’t need to have to work up the motivation to stay in ketosis, it just became a natural side effect of how I was feeling… I also went muay thai lessons for fun. Before I knew it, my pants were falling to my knees. I was amazed when I realized that losing body fat wasn’t even my greatest intention: my greatest intention was to feel this good, and the shedding of the fat followed.

In just 4 months I managed to look like in the pictures below, my mind is consistently clear and sharp, I naturally desire to eat incredibly healthy, and my body is fast, strong, flexible, and leaner than I could have ever imagined.

Just check out my before and after pictures, between 4 months of using Pruvit Keto//OS. I couldn’t believe the results. But it happened. It was true.

4 months After Starting the Ketogenic Diet And Supplementing with Keto//os


How does it tastes like?

Through this entire journey, my only complaint about Keto//OS would have to be the taste. Sure, initially, it wasn’t pleasant — it was far from the cola and kool aid I was used to. However, after my connotation to the taste became that of how it made me feel, I drank it with no problem. It’s definitely something that my mind and mouth happily got used to.

Plus, you can always add lemon to help with the taste.

I never thought I’d be one to write keto-os reviews, but here I am, happily doing so.

How does it compliment Keto Diet Plans?

As I mentioned before, exogenous ketones are a supplement, not a substitute. It’s important to still follow a keto diet to the best of your ability.

For me, cutting out sugar was the most difficult part of the diet. Oh yeah, and cutting out beer (which is a sugar). Luckily, these exogenous ketones can really help if you have a cheat day here and there. When I drink a beer, I always take KetoOS alongside it to help compensate. This prevented me from fully falling out of ketosis and experiencing the infamous keto-crash.

Comedian, UFC host, television star, and podcaster, Joe Rogan explains in, The Joe Rogan Experience,  in the below podcast clip how he would use Keto OS in a similar way. He also notes how the taste isn’t the best, but it’s not that bad.

I would especially use Keto OS before my workouts, jogs, and muay thai classes; I feel like it really gives me that extra endurance boost. Also, I use it as an aid when I need an extra boost in mental performance.

While some people may refer to taking these supplements as ‘cheating,’ I like to refer to it as biohacking.

Are there any negative side effects?

When I first began taking KetoOS, my stomach had a difficult time adjusting to it’s ingredients. Some people experience this initial digestive discomfort, which is why I recommended (above) to introduce it to your body slowly by starting with only ½ the dosage.

Also, as it’s your body’s natural process to flush out glycogen stores, you may notice an increase in urination. Just remember that every time you urinate, it is incredibly healthy and detoxing! I had to drink an unusual amount of water for this reason. Luckily, Keto os has sodium added to it’s formula to help your body with this process.


Wondering what ingredients work all this magic? Check out the short list below, it’s a much simpler recipe than most people would initially guess.
