Keto OS Review


Pruvit Keto OS is widely seen as a fix-it-all weight loss supplement that allows people to enjoy all of the benefits of a Ketosis diet without having to eat a limited diet that is devoid of carbohydrates.  Keto OS includes energy boosters, ketones, and Amino Acids as its primary ingredients to supply these supposed effects.  Let’s take a look at the ingredient list for Keto OS in detail below


Keto OS 3.0 Chocolate Swirl contains the following: Beta Hydroxybutyrate, Amino Acid Blend (L-taurine, L-tyrosine, L-arginine, L-leucine), Natural Flavors, Inulin (Chicory Root), Potassium Citrate, Stevia, Caffeine, Ascorbic Acid, Butyrate.

Beta Hydroxybutyrate is a ketone produced in the body when the fasting process begins that helps the body to dissolve fats and convert them into energy.  By having more of these in the supplement, it allows us to build on the amount our body is already producing.  This is thought to increase the effect of the Ketosis stage our body has entered and grant us results faster.

Amino acids are essential products in the body for recovery after exercise.  They allow the body to break down lactic acid and rebuild muscle tissue.  Lactic acid is what makes us feel sore after we exercise and causes us to feel fatigued and drained in the days following our workout.  The best options to combat this are movement and Amino Acids.  This makes Amino Acids essential in almost any workout or dietary supplement.

Inulin is a water-soluble fiber that is found in many plants.  Unfortunately, the fiber is mostly indigestible by the human system until it reaches the colon.  At this phase, the primary response to its breakdown is the increase of gas in the digestive system resulting in bloating. There are no known positive effects that haven been proven to come from Inulin and it serves no real purpose in the supplement, at least not that can be proven as of yet.

Potassium Citrate helps kidneys to filter out uric acid which is known to cause gout and kidney stones.  This can be beneficial since a correlation has been shown between supplement use and kidney stones.  With a Ketosis diet, supplements are used in abundance for many people and Potassium Citrate could help limit the likelihood of kidney stones occurring.

Stevia is an artificial sweetener that has no carbohydrates.  This is essential for a Ketosis diet to make something sweet.  Unfortunately, most artificial sweeteners have a laxative effect on the user.

Caffeine is a chemical that increases energy and focus.  This is more than likely the largest source of energy boosting in this mixture and could be achieved with coffee, soda, and many other sources.

Ascorbic Acid is the chemical form of vitamin C and is known for granting slight increases in energy and feelings of overall well-being.

Butyrate helps to maintain colon health by helping to provide energy to the cells lining the wall of the colon.  This is going to be essential in this supplement with the amount of ingredients with a laxative effect in the supplement.  The Butyrate would assist the body in replacing the colon cells it is losing and improving the general health of the organ.

How it helps with a Keto Diet

Keto OS is meant to supplement all of the benefits of the Ketosis diet that the body should already be producing.  It adds additional ketones to the ones your diet should be creating, supplies the body with extra energy sources, and supplies a boost in Amino Acids for recovery.

What are the benefits?

Users can expect a boost in energy and a reduced duration of soreness following exercise.  They can also expect a very slight increase in the effectiveness of their Ketosis diet due to the increase in ketone intake.

Side Effects

Due to the ingredients list of this supplement, users can expect nearly a guarantee to be plagued with irritable bowels and urinary frequency.  Caffeine, Inulin, Ascorbic Acid, and Stevia are natural laxatives and diuretics.  Users should also expect a moderate amount of bloating due to the way Inulin is dissolved in the digestive system.

Pros and Cons

Keto OS is likely to give the user an energy boost akin to drinking a caffeinated soda or coffee and a recovery boosting effect in their exercise routine similar to drinking chocolate milk.  However, the user is likely to experience frequent discomfort from the use of this product through an overactive bladder, bloating, and irritable bowels.


  • Boosts Energy
  • Enhances Exercise Recovery


  • Not much benefit for the price
  • Easily recreated in your diet
  • Bad intestinal and bowel effects

Conclusion – Does it really work?

In the end, the only real question is whether or not the supplement works.  The supplement is in many cases not going to do what it claims, that much is certain.  The user will not get the benefits of a Ketosis diet while maintaining a normal diet. 

That simply isn’t going to happen with any supplement on the market.  It may help the user lose weight, but that is more than likely due to the gastrointestinal irritability than the ketones. 

Honestly, you’ll get more benefit from drinking a cup of black coffee and sticking to the Ketosis diet than you will from this supplement.  Your stomach will feel better in the long run as well.
