Pruvit KETO OS 


Muscly Guy in Pool

I'm Mike and I've been a personal trainer for over 10 years and I first heard about ketosis way back before it was even a big thing. I've been more or less on the ketogenic diet full-time ever since.

When Keto-OS came out, people had been talking about Keto-OS being the go-to product for quickly getting into ketosis and even allowing you to cheat.  

Me being a skeptic, I set out on a 3 month strict review project, to get to the bottom of whether or not Keto-OS actually works. After months of testing blood samples and body calibrations, I am about to give you the conclusion of what I found  from my review down below. 

What is Pruvit Keto-OS?

KETO OS is the latest product from Pruvit and stands for "Ketone Operating System." This product is an exogenous ketone drink, which means it may provide a multitude of benefits, ranging from athletic performance enhancement, more efficient weight loss, cancer prevention, cognitive improvement and anti-inflammatory properties, among other things. Its ability to essentially trick the body into burning fat instead of carbs (a state known as ketosis) can also result in more rapid weight loss than you may have thought possible.

This is what Pruvit had to say:

Keto-OS is your “ketone operating system”. It was one of the  First Therapeutic Ketone Supplements on the market. The proprietary blend is owned by Prüvit and is Dr. Approved, Lab Tested, University backed and the technology in Keto-OS is patent pending, developed by one of the most world renown Dr.’s and experts on Ketosis. Prüvit was the first company approved by University of South Florida to acquire the sub-license rights to use this patent pending technology. It is a powder that you mix with 8=10 oz. of water. Keto-OS is Pruvit’s flagship product and is the first product the company sold when it started back in 2014. Keto-OS has a certificate of analysis for purity, consistence and efficacy.

Pruvit KETO OS has used a blend of mineral salts and coconut extracted MCT oil in this product that is promised to deliver fast results as well as the following:

  • Increased energy
  • Effective protein synthesis
  • Rapid weight loss
  • Mental clarity
  • Hunger suppression
  • Improved sleep
  • Sense of wellbeing
  • Reduced inflammation

This is a great short video that will give you a better understanding of exogenous ketones if you are just getting started on a ketogenic diet or are struggling with the process. After watching it, we will discuss more on how and where to buy KETO OS in this review article. 

My Own Pruvit KETO OS Review

Through all the hype, what really caught my eye about this ketogenic drink was all the research that had been conducted at the University of South Florida by no other than Dom D'Agostino. Dom is an Assistant Professor at USF and a Senior Research Scientist at the Institute for Human and Machine Cognition.  As of mid-2016, Dom's experience and expertise are unmatched in the keto world.

This is the man who dead lifted 500 pounds for 10 reps after a one week fast. He is also responsible for developing the technology in this product. Discovering this made my interest deepen. I had finally made the decision to buy the product and give it thorough review. Unlike most other KETO OS reviews that you see all over the internet, I have waited a significant amount of time to test this product thoroughly and document my daily experiences, because I really wanted to see if the experts were really right about this product.

Using Pruvit as a Pre-Workout Supplement

​I had read a lot of reviews and positive testimonials of people saying that Pruvit KETO OS is an amazing pre-workout and thought I’d give it a try before my next gym session.  I have to say those reviews were spot on! It was truly amazing. A lot of pre-workouts make me very jittery and almost anxious.

Have you ever headed to the gym, felt laser point focused and just had a steady stream of energy that made you feel amazing? Well, this is the exact feeling I get when taking a pack of this 35-45 minutes before a workout, EVERY TIME. I highly recommend you try this for a pre-workout and see for yourself. “Boosted energy and focus for a hard gym session and a helping hand in burning fat all at the same time?” I hear you say. Absolutely and I urge you to try for yourself. 

How It Helps With Ketogenic Diet Plans

If you're reading this review, then by now I'm sure you already know what a ketogenic diet is and the principle is the same as where you consume high fat, moderate protein and very low carbs bringing your body into a state of ketosis. This supplement does the exact same thing.

After taking this supplement, your body burns ketones as fuel instead of relying on glucose. Your body will also go into a very effective fat burning mode which will go on for a while and work in helping you lose weight. So, that's great!

Although many people use this as a complete substitute for nutritional ketosis, you will find the best results when using it as a fallback when you cheat on your diet, or on those days when you really need that extra energy from some carbs to smash a workout. Personally, I like to take it to assist my performance and endurance when snowboarding. I can literally do 4 to 5 runs before I even get hungry.

Recently on his popular podcast “The Joe Rogan Experience” UFC commentator, comedian and martial artist Joe Rogan recounts the times he has knocked himself out of ketosis by eating natural sugars. To counteract this, he used Pruvit KETO OS when he strays from his diet and was happy to give it a little review during his show.

Is KETO OS Safe?

Having read and researched all the ingredients that go into Pruvit KETO OS, through their website, forums and reviews, we could see that it was a safe and fast method of entering a natural metabolic state. Having tried it myself, I monitored for any adverse effects and could not find any. So, having said all that, I believe that this product is a good buy for anyone looking to lose weight really fast.

Just remember as with any supplement eat well, exercise regularly, maintain your calories, drink plenty of water, sleep right and you will make a positive impact on your body when using this product.

Are there any Side-Effects?

Acting as a minor diuretic, you may need to urinate more frequently. This is expected, as it’s a natural process for your body to flush out glycogen stores during the process. Any loss in sodium is counteracted by KETO OS supplying additional sodium to the formula.

A small amount of digestive discomfort can be experienced by people. However, I didn’t experience much of this distress. It may be the way I prepared mine, which I will reveal to you below in the results section. So, I suggest you sit tight and keep reading on because you're going to want to read this bit of information. 

What's in Keto OS Ingredients?

The products key ingredients are the BHB, beta-hydroxybutyrate with the clever addition of MCT oil, which aids in slowing down the rate of digestion. This approach gives us a product that causes minimal stomach issues, which can be the make or break for most supplement users.

BHB is the source of exogenous ketone bodies in the drink. Using BHB has been a smart move by Pruvit as it is highly effective at being utilized by the body tissue and being oxidized back to acetoacetate to then be utilized.

The components in this product are:

  • BHB
  • Medium Chain Triglyceride Powder
  • Natural Flavor
  • Malic Acid
  • Stevia
  • Caffeine

The Results From My Review

#1 - How I Felt

The first day I used Pruvit KETO OS, I started out slow and halved the dosage. Over the next two days, I increased the dosage and my reaction was ‘Holy cow!’. A noticeable increase of energy and focus was apparent. Over the past 3 months, I’ve been going through my days energized and with increased awareness all thanks to taking this product every single day.

The focus and energy you get from this supplement are on par with being in a deep state of nutritional ketosis. You feel an abundance of energy and because you avoid nasty insulin spikes, your brain doesn’t crash in the afternoon. Goodbye brain fog and hello mental clarity.

I always feel depleted from dieting and having to do meal prep into 100 containers of food. On top of this, I still feel hungry most days. Now that I’ve been taking KETO OS, I can carb up prior to hitting the gym or snowboarding, still be on track with maximum amounts of energy and have a killer workout.

Having the endurance to do more snowboarding has made all of my runs improve. I’m getting out there more often which has helped me improve overall and made snowboarding more enjoyable and competitive. I’ve seen gains in muscle mass, strength and stamina in the gym which I never experienced when I'm not following the program.

#2 -  How I Looked (Before and After)

keto os before and after

Like many health supplements on the internet, people are always searching for 'before and after' stories and photos from the experience of using a product. Well, here is my own 'before and after' story of using Pruvit's Keto OS. I hope you guys enjoy this journey of mine.

After using this supplement for a week I noticed some changes in my weight and how my body felt overall. To be honest, it really felt amazing being in that kind of shape. Over the following weeks my results continued to improve dramatically. The energy, the feeling, the improved physical appearance. It's really addictive to be in that kind of moment. After taking it for a while you will get used to the higher quality of life with the better overall physical condition along with the mental clarity. There is no going back for me. 

So, there you have it and that's my story. 

Lose Weight & Burn Fat Fast

While using this supplement, I expected some weight loss. This is, of course, the main reason people buy these supplements. As the product is designed to raise your BHB levels in your bloodstream, your body will switch to a constant fat burning mode. Even though I was trying to gain muscle mass, I noticed I dropped a significant amount of body fat during the first month.

For those looking to lose weight and burn fat, this supplement is a win-win. Putting you into a fat burning state will not only burn off your fat stores, but Pruvit acts as an appetite suppressant. It helps to keep gherlin, also known as the hunger hormone, at bay, which eliminates the feelings of snacking or over gorging your next meal, which is why I can't help but give this review about it.

Great For Suppressing Your Appetite

When I’m finished gaining some mass and want to start shredding some body fat, I’ll up the intake of KETO OS to help with my appetite suppression during the night time, yet I’ll aim to still carb up before very intense workouts. My best friend has been doing this with great results and is dropping nothing but body fat every week.

In the end, I’ve been using this supplement for 3 months now and I love it. I test my ketone levels all the time and find that I am usually around 1.5 – 2.5 mmol/L. Surprisingly my cravings for sugars and carbs has been completely removed.

This supplement has changed my daily eating and training habits for the better. I’ve been trying to build more muscle mass, which is a major challenge when trying to maintain low carb levels.

What Does It Taste Like?

As far as taste goes it’s fine, I’ve had worst, but my recommendation for those sensitive to sweeteners or flavors is to mix the powder with coconut water or unsweetened almond milk. It just helps out to make the taste of the product more balanced and actually not that bad. After giving the recipe a shot myself, I wouldn't really complain about the taste of it  anymore unless I was really having a bad day. So yeah, it helps!

Make sure that the coconut water is extremely cold and add some ice. Everyone has been mixing it with water. Come on people, where’s the imagination?

So, Does KETO OS Work?

the real answer from the review

This product is perfect for people starting out, who are struggling with weight loss. You can slowly ease into refining your nutritional keto while taking this supplement. For those of you who have already adapted, but have trouble finding the energy to power through your workouts, this can be your source of stable insulin free energy that lasts for hours.

Pruvit KETO OS is a great drink for so many reasons. There are many benefits gained from this product including fast sustained energy, cognitive functioning, reducing chronic inflammation, improved blood pressure and fat loss. It has a lot of research articles backing its claims in PubMed and from my personal experience, it has improved my overall lifestyle. I didn’t want to believe the hype myself, which is why I took the time to do some intense bio medical research to see if this product really works and after conducting numerous tests over several months, I can officially say, I love this product and am so glad I decided to try it out. 

How does it compare to the #1 product Perfect Keto?  I'm on the fence, but you can read a comparison review here.

Where to Buy Pruvit Keto OS?

So, I guess the last question on this review that needs answering is where exactly can you buy this product? Well, the best place to buy a product as always is directly from the Amazon. It can guarantee that you get the right product at the right price with great customer service. 

I'm looking forward to what they bring out next and can't wait to let you guys know all about it in my next review.
