How Pruvit Keto-OS Works?
Pruvit’s range of products are 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[1]. It comes in the form of a drink mix so that it may be conveniently taken along with a supply of water.
Pruvit Keto-OS Ingredients – Are they Safe & Effective?
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[2].
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[3] on the benefits of ketosis, there is no clear research on this product itself.

Pruvit Keto-OS Review – Final Verdict
Compared to many other diet supplements, Pruvit appears to be based in 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 other products available on the market today, and we encourage you to do thorough research before you spend your hard-earned money.
