How Does It Work?

Pruvit’s range of weight loss supplement is intended to start the process of ketosis inside of your body through the use of ketones derived from other sources, instead of having to try to achieve that state inside of your body with a very low carbohydrate diet.

It comes in the form of a drink mix so that it may be conveniently taken along with a supply of water.

What Are the Ingredients?

The exact amount of various ingredients in Pruvit’s drink mixture is not made readily available, although Keto OS does describe the key active ingredient, which is Beta Hydroxybutyrate.


*All individuals are unique. Your results can and will vary.

This substance is naturally produced by the body during ketosis, and the theory is that by consuming it directly, your body will enter that biological state more easily, giving you the various related benefits.

It also contains some vitamins and minerals, as well as Stevia powder (for sweetness), and in some formulations, caffeine.

However, the exact amount of these ingredients are not listed, and while their website describes some studies on the benefits of ketosis, there is no clear research on this product itself.

Beta Hydroxybutyrate

– When the body’s supply of glucose is insufficient to meet its energy requirements, as occurs during extended periods of physical activity, famine, or food deprivation, the ketone body -hydroxybutyrate (BHB) is generated in the liver from fatty acids[1].

Stevia powder

Stevia is frequently promoted as a secure and beneficial sugar alternative that may be used to sweeten food without the risks to one’s health associated with refined sugar[2]. Additionally, it has been linked to a number of remarkable health advantages, including lower blood sugar levels, calorie consumption, and cavity risk.


– In the short term, caffeine can boost the metabolic rate and increase fat burning.

Pruvit Keto-OS Reviews from Customers

Pruvit Keto-OS is a good product. Love the product. I used this product for 3 months, and I lost 20 pounds of weight.- Jenny

Pruvit Keto-OS Reviews – Final Verdict

Compared to many other diet supplements, and as per Pruvit Keto-OS reviews, it appears to be based on some clinically backed science and comes in a range of convenient sizes.

Their money-back guarantee is also rather generous.

However, there is no scientific evidence cited that their particular formulation is going to have resulted in accord with what they describe, and the price is very high, especially taking into account that you are expected to work up to consuming three servings’ worth per day!

There are many similar products such as Plexus Slim, 310 Shake and Isagenix available on the market today, and we encourage you to do thorough research and compare Pruvit Keto-OS with top rated diet pills before you spend your hard-earned money.

‘Pruvit Keto OS’ can be purchased through their Official WebSite.

    I Shouldn't Have Bothered
    I was made aware of this product from a friend on Facebook. This ploy showed her drinking something and talking about how good it made her feel. So, I innocently asked what she was drinking, and she created a group chat for me and someone else who proceeded to tell me all about the product and trying to sell it to me.

    Not a nice thing to do to your friends. Totally. Not. Cool.

    But I bought some (and paid 65 dollars for ten packets, which means you’re paying 6.50 for an energy drink). Overpriced.

    This sales rep sent me the ten packets, which I’m over halfway through right now.

    To be blunt, it isn’t working. And it’s likely making things even worse for me.

    As I explained to the rep, I was already in ketosis as an adherent of the carnivore diet. And I was doing fine with it. There was no need for me to take ketones. But she insisted that it could be helpful, even if I was in ketosis and that friends of hers tried and it was successful with it.

    I have lost no weight with it. In fact, I gained some. The product contains Stevia and no one should be taking sweeteners, not even natural, non-calories, on a ketogenic diet.

    While some were okay, some of the assorted packets I was sent are outright awful. The Holy Grail, for instance, is nasty!

    So, overpriced, ineffective, and unpalatable.

    It works but very pricey
    I have never tried a keto supplement before, and Pruvit Keto-OS was the first one I tried, and I really liked it. What I don’t like though is the price tag. It’s the best weight loss supplement I have used so far and leaves me feeling energized and healthy. I gave my sister an extra bottle of Pruvit Keto-OS, but it didn’t work for her. She wanted to regain her lost waistline and shape due to being overweight. However, it has worked for me because I am no longer plump, and I love my new look. I will continue taking Pruvit Keto-OS, but my only concern is the pricing and how it doesn’t work on different individuals.
  3. Carmelo C

    Doesn’t do enough in my opinion
    I was very excited to try Pruvit Keto- OS after discovering it, and I must admit that I do feel a little more energized since using it, but I am a large guy and have a significant amount of weight to lose. As such, it should be doing more than just giving me a little extra energy, because in theory these ketone bodies are supposed to help me stay in a state of ketosis to promote accelerated fat burning. I don’t think I would invest in it again since even though I do feel more energized, to be honest, I expected much more from it after using it for so long.
  4. Jack L.

    Need a body size reduction
    I’m just way too big and I really wanted to trim down. I needed something that could help me with that. I thought maybe Pruvit Keto OS would help me, but so far I am seeing very little results. Still, some results are better than none, so I guess I am torn about what to rate this product.
  5. Claire E

    I’ve used better products
    At first I thought Pruvit Keto OS was working, because I lost a couple of pounds and it seemed to help suppress my appetite too, but after a while, I stopped losing weight and felt hungry again. I guess once my body got used to it. I’m not sure why. Overall, I’m not happy with this product.
  6. Eugene A.

    It Works, But It’s Costly
    I’ve been looking for a product that would help me get back into Ketosis after I had a day or two of falling off the wagon so to speak (really setting it on fire and watching it burn would be an accurate description). And with parties galore during graduation season and proms and this and that I’ve been enjoying myself. But I hate the process of getting back into Ketosis even though it works. So I bought Pruvit Keto-OS. It was a little expensive but my wife surprised me with it. So I tried it and it worked. In no time at all I was back in Ketosis and losing weight. I used the caffeine free version and I was able to maintain the weight loss I wanted and continue on to getting to where I want to be. Now as for monthly purchases, I don’t know about that, it’s quite pricey so I might stick to it while I am losing the weight but when I am done (I’m not that far away honestly) I might not be able to continue with the product only because of the cost.
  7. Tiffany

    Try ketosis on your own before trying this!
    If you are trying to get into the state of ketosis, it can be complicated to get everything just right. This drink should help you with that. When I say should, I mean it really doesn’t. You are better off trying to go through the process with your diet, as it is easier than trying to take a shortcut with this product. I tried some and they do have a good taste, but other products do also. It isn’t worth the price since this price is very expensive. It costs hundreds of dollars and you still have to work out and follow the diet you are already on.
  8. Natalie C

    Losing weight
    I’ve lost 20 pounds over the past four months with Pruvit Keto OS. I feel so much better. I have more energy and about two months ago, I started walking a couple of miles a day. I also cut out most carbs. I sometimes eat ice cream, because that is my weakness! Even with that, I’m still losing weight. Now that I’ve reached my 20-pound goal, I’m really happy. My next goal is to lose another 20 pounds. I highly recommend this product!
  9. Randy M.

    Gets you into Keto, but it is Expensive
    I used this product to help get my body into ketosis, and it does it over time. I did notice results when I did use this, and I was pretty satisfied with it. However it does have the downside of being incredibly expensive, but it is one of the few ketone products on the market, so you’re paying a high price for quality products, which in turn will allow you to get the results that you want from this, so it definitely is something to consider if you have the money.
  10. Roger D

    Did not help produce ketone bodies
    I have been an enthusiast of the ketogenic diet for many years, so I was thrilled to discover products such as Pruvit Keto-OS that claim to be able to help in the production of ketone bodies. After using it, however, I no longer have faith in them. I did not notice any improvement in my energy levels, instead, I just felt like it caused gastric disturbances in me. I had bad flatulence and bloating, and unpredictable diarrhea. I had stopped using MCT Oil while I was using this, and it just appeared to set me back. Needless to say, if you have read about exogenous ketones don’t buy into the hype.
