Keto OS Max Review


Keto OS Max Product ImageDoes this popular keto drink really have what it takes to deliver the results for consumers? The product has seen significant promotion and hype lately, so we had to take a look for ourselves.

In this Keto OS Max review, we’re looking at exactly what users can and cannot expect from this popular product.

Readers please note that statements on this page are fair comment based on observation. This content is produced on a matter of public interest. Statements on this page are our honest opinion.


What Is Keto OS Max?

Keto OS Max is ketone drink that is formulated with Beta Hydroxybutyrate (more popularly known as BHB) by a brand named Pruvit.

While the manufacturers have never actually claim that this is a weight loss drink, the word on the street is that Keto OS Max is designed to help boost user energy levels and induce the onset of ketosis – the state in which the body starts using body fat reserves for energy.

The product is manufactured by a US-based company named Pruvit Ventures, Inc (trading as Prüvit). To date the company has a 67% negative feedback on the Better Business Bureau database, with a total of 13 customer complaints filed against them – it seems every customer complaint has been resolved which shows decent customer service. (source:

One pack of Keto OS Max contains 20 OTG (on-the-go) sachets and costs a rather hefty $130, which works out at $6.50 per sachet. A 20-pack will last users between 10-20 days depending on whether they want the “therapeutic dose” of 1 daily serving or the “optimal performance” dose of 2 servings daily. The product is available in caffeine and caffeine-free versions.

This product is available from the official Keto OS Max website as well as the Amazon marketplace, GNC and. We are unsure if this product is available in stores.

Users of Keto OS Max are promised “optimized cellular regeneration, energy and longevity.” Consumers should note the complete absence of claims that this product will help induce ketosis or cause weight loss.

Does Keto OS Max Work?

Based on our research into this product, we do not believe it will work as most people expect it to (as a weight loss drink), but it will work as Prüvit describe, which is as a general health drink that promotes energy and longevity.

When critiquing a product, we have to be careful to take note of what the manufacturers actually claim originally; this product is marketed as a general health drink, not a weight loss drink, and for all intents and purposes we believe that this product will indeed help boost user energy levels and contribute towards general health.

If you assumed Keto OS Max was a weight loss product, then sadly you’re mistaken. There are no fat burning ingredients inside this product and it won’t really induce “Ketosis” – for that you’ll need to actively stick to a Keto diet.

The main ingredient inside Keto OS Max is BHB (Beta Hydroxybutyrate), it’s an exogenous ketone body which the body can convert into acetoacetic acid, which raises your blood ketone levels. Having high levels of blood ketones may have anti-inflammatory effects, it may also improve cognition and boost your energy levels (source:

To put it simply, Keto OS Max is a feel-good, longevity product and not a weight loss product.

On a side note: Raspberry Ketones and Ketone Bodies are two completely different things.

This product is extremely expensive… BUT IT WORKS…. I use it daily M-F giving myself the weekend off, but still committed to the keto eating plan. I have really noticed increased energy, clarity, and better sleep.

Did nothing for me. I drank two a day on a low carb diet and gained 2 lbs. My wife drank one a day and lost no weight at all.

Currently, the product has a 3 star rating on the Amazon marketplace. Based on the FakeSpot Software, there doesn’t seem to be any manipulation of the product reviews (source:

Our Final Verdict On Keto OS Max

To conclude our Keto OS Max review, it’s a bit of a mixed bag – there are things that we like about it and things that we aren’t too blown away by to be used for the purposes of weight loss.

For all intents and purposes, this product is great if you’re just planning on using it for general health purposes, however it is extremely expensive and you could probably get similar health benefits by just eating cleaner and sticking to a keto diet (but if money is no object then go ahead!).

There are no fat burning ingredients inside this formula, and despite it having a similar sounding name to the popular weight loss product raspberry ketones, there is absolutely no similarity. Again, do not expect to lose weight while using Keto OS Max.
