Keto OS Max Review

Looking to burn fat & lose weight?🔥🔥

Check out our #1 recommendation for fat loss, weight loss & diet success:

Keto // OS Max is a ketogenic drink sold as a powder that you take twice a day. Pruvit, its manufacturer sells it under different names. You must add water and take it twice a day. At this rate, it becomes pretty expensive as you are about to see.

This product is promoted as a great supplement to help lose weight through sustained ketosis and combined with exercise. In general, we believe the product is overpriced and there is no solid evidence that it actually works the way it claims it does.


Keto // OS Max Ingredients

This supplement is dairy free and gluten free. The usual presentation is one box with three sachets. Each one of these is approximately 18.4 g.

The ingredients are the following:

  • Beta-Hydroxybutyrate: No strong evidence about what they do but they are thought to regulate how the body uses energy.
  • L-Taurine: Component found in Red Bull; was believed to increase mental alertness but that has been disproved.
  • Erythritol: Sugar additive with zero calories.
  • Malic Acid: It helps to increase energy levels.
  • Fermented L-Leucine: Amino acid used by the body to synthesize proteins.
  • Caffeine: According to Pruvit, this supplement contains an amount of caffeine equivalent to a cup of coffee.


Keto // OS Max Claims

According to claims made by the manufacturer, this product is almost nothing short of a health panacea. Some of the key features detailed are:

  • Increased awareness and reduced brain fog.
  • Assists in abdominal fat loss.
  • Increases strength and reduces inflammation
  • Helps regulate mood swings.
  • Fast and sustained energy.
  • Invigorates your sleep making you wake up fresh and recharged.

The website includes numerous pictures of people before and after taking the product. There is no palpable evidence that they got the results from taking Keto // OS Max.


Keto // OS Max Guarantees

This product does not offer any money-back guarantee. Do consider that each pack comes with only three sachets. That is three individual uses which you will use up in less than two days. Placing a money-back guarantee does not seem too profitable for Pruvit.


How Much Does Keto // OS Max Cost?

Keto // OS Max is very expensive. A box with three bags costs $28.99. That is $9.66/count.

A pack of 20 servings has a price of $130-$6.5/count. Subscribing to auto-ship saves you $15. This is the price that Pruvit gives to Keto // OS Max promoters (Pruvit is an MLM), so there is no much profit if you decide to sell this product.

You can also buy a package of 7 sachets on Amazon, giving each count a cost of $6.99. Amazon also sells packs with other amounts. Of course, the larger the box, the less the cost of each individual bag.


How to Take Keto // OS Max

Since Keto // OS Max comes in very convenient individual packages, all you need to do is dissolve one in 12-16 oz of water and stir vigorously.

The solution can be taken with or without food.

The therapeutic dose is one package per day but for optimal results, the manufacturer recommends drinking two per day, one in the morning and one in the afternoon.

Not that you need the math spelled out to you but I want to point out that the optimal dose is the equivalent of $13 daily! That is a lot of money, especially considering that there are equally good or even better supplements out there at a more affordable price.


  • It can be taken with or without food.
  • This supplement is dairy free and gluten free
  • can be taken twice a day


  • Does not offer money-back guarantee
  • It is very expensive
  • It has side-effects
  • There is no solid evidence that proves it will work

Does Keto // OS Max Work?

If we look at the ingredients in Keto // OS Max, we do not have any reasons to believe that it actually works. There is nothing in the formula with solid research that would help Pruvit live by their word that this supplement boosts energy, improves sleep, or any other of the claims stated.

I will not go as far as completely bashing the product. There is still a chance that it might work in some cases but never at 100% of its claims.


Is Keto // OS Max a Scam, or is it worth the money?

This is a product that has been around for a while. Now, the fact that it is manufactured by an MLM company and the high price, makes it look like a scam. But, volitionally, it is not. This is a keto blend containing ingredients that have some support on working the way the manufacturers claim to do it does.

I don’t believe this is worth the money, especially considering that there is no money-back guarantee. You will need to spend some serious cash before realizing if it working for you or not.


What Are The Side Effects Of Keto // OS Max?

The ingredients described in Keto // OS Max are not harmful and should not develop any major side-effect. However, Beta-Hydroxybutyrate can cause gastrointestinal distress. We do not know in what amounts is this substance present in Keto // OS Max, but since we have read reviews on side-effects, we will venture to say that it is present in amounts sufficient enough to cause:

  • Upset stomach
  • Diarrhea
  • Abdominal pain
  • Gas
  • Jitters
  • Anxiety
  • Insomnia

It is always recommended that you consult with your physician if you should take this or any supplement. Keto // OS Max is not intended for individuals under 18. You should avoid it if you are pregnant or breastfeeding.


Keto // OS Max Concerns

Summarizing what we have collected from our research and Pruvit’s claims about this product, there are three important things that concern me about Keto // OS Max:

  • It is very expensive so you will have to incur into some thick expenses.
  • There is no solid evidence that proves it will work.
  • Not enough information on the effects of BHB to discard any side effect.


Keto // OS Max Customer Reviews

Keto’s reviews as mixed for the most part. Now, some of the great reviews the product gets do not feel genuine. The website filters the bad ones.

Let’s start with the bright side and take a look at some reviews of people that this product worked close to or how expected.

“I so love this product! Gives you that boost you’re looking for and it actually tastes great. A little sweet but drinkable with no after taste.”

I always enjoy this product thank u”

“I put on 30-40 pounds when my wife had our baby. When I first tried KETO//OS, I felt like superman in 20 minutes. I’ve lost 44 pounds so far with this product!”

There are plenty of negative reviews. As you will see most of them are focused on the points we have been highlighting here: no evidence that it works and it is very expensive.

“Waste of money!”

“Product did not work at all for me! I tried it hoping it would help put me in Keto sis . I used testing strips and it never did and I followed the Ďįẹť! I used another product half the price that worked perfect! Will not buy again and it also didn’t help my energy levels !”

Just started this, I paid 35.00 for 5 packs, a trail pack. The flavor was better than most I’ve tried. The price too high. I got sick the first day, nauseous,stomach pain. Just felt like I had the flu. Was told to eat protein the next day before I took it. Was a bit better but that feeling of wanting to barf came back. I will not take this again and wish I would of read this before purchasing but I was trying to help out a friend daughter who is so pleased with this product.”


Where to Buy Keto // OS Max?

You can buy this product from a Pruvit promoter or directly from the Pruvit website. You can also find in on sale in Amazon.


Final Decision On Keto // OS Max

I will start my statement by saying that this product is unnecessarily expensive. To have optimal results, you will need to take two bags a day. That adds up to $390 per month! Besides this, I question that this product will effectively help you lose weight or fulfill most of the other claims.

There is no evidence that BHB will work as described. As with malic acid, we already know about its benefits. What we do not know is in what amount it is present in Keto // OS Max, therefore, there is no way to know if it will have the desired effect.

Verified users have stated some side-effects on this product. This could be an indication that it has enough BHB to irritate your intestines.

Allow me to remind you that Pruvit is a multi-level marketing company that does not seem to offer many benefits to its promoters. There is no point in selling a product to promoters at almost the same price as the public.

There are better options out there at a much lower price. Unless you have money to spend and give this product a try for a longer period of time, maybe you want to stir clear of it.
