Exogenous ketones have gained considerable popularity among individuals adhering to ketogenic or low-carb diets. These supplements are available in various forms, including powders and pills, and are marketed to provide benefits similar to those experienced on a ketogenic diet. Pruvit is a prominent company in this market, offering its Keto//OS line of exogenous ketone supplements. This article will delve into the ingredients of Pruvit's Keto//OS products, explore their potential benefits and risks, and provide a comprehensive overview to help consumers make informed decisions.
Understanding Keto and Ketones
Before diving into the specifics of Keto//OS, it's essential to understand some fundamental concepts related to ketosis and ketones.
- Ketosis: A metabolic state where the body primarily uses fat for energy instead of glucose. This occurs when carbohydrate intake is severely restricted, as in a ketogenic diet.
- Ketogenesis: The process by which the liver converts fatty acids into ketones.
- Ketones (Ketone Bodies): Compounds produced by the body as an alternative energy source when glucose is limited. The three main ketones are acetoacetate, beta-hydroxybutyrate (BHB), and acetone.
- Endogenous Ketones: Ketones produced naturally by the body through ketogenesis.
- Exogenous Ketones: Ketones supplied to the body from an external source, such as a supplement.
What is Keto//OS?
Keto//OS, short for "Ketone Operating System," is a line of exogenous ketone supplements manufactured by Pruvit, a company that describes itself as a leader in ketone technology. These supplements come in powder form and are designed to be mixed with cold water. Pruvit recommends consuming Keto//OS once daily for therapeutic benefits or twice daily for optimal performance.
Keto//OS Ingredients
The primary active ingredient in Keto//OS is beta-hydroxybutyrate (BHB), the most efficiently used ketone body in the body. In addition to BHB, Keto//OS contains:
- Caffeine: A stimulant known for its energy-boosting and cognitive-enhancing effects.
- MCT (Medium-Chain Triglyceride) Powder: A type of fat that is easily converted into ketones by the liver.
- Malic Acid: An organic compound that contributes to the sour taste of some fruits and is involved in energy production.
- Ascorbic Acid (Vitamin C): An essential nutrient with antioxidant properties.
- Stevia: A natural, zero-calorie sweetener derived from the stevia plant.
- C-Med 100®: A Pruvit-exclusive ingredient that is associated with several proposed benefits, including healthy cell function, DNA repair, and increased amino acid production.
It's worth noting that Keto//OS supplements are gluten-free but contain milk ingredients.

How Keto//OS Works
Pruvit claims that Keto//OS can induce a state of nutritional ketosis within 60 minutes of consumption. This rapid entry into ketosis is attractive to those who find it challenging to achieve ketosis through dietary means alone, as the ketogenic diet typically requires strict adherence to a high-fat, low-carbohydrate intake, which can be difficult to sustain.
Exogenous ketone supplements like Keto//OS provide an immediate supply of ketones to the body, raising blood ketone levels even without dietary changes. The ingested BHB is absorbed into the bloodstream and utilized as an energy source.
Potential Benefits of Keto//OS
While research on exogenous ketones is still evolving, several potential benefits have been suggested.
- Improved Athletic Performance: Exogenous ketones may enhance athletic performance by providing an alternative fuel source during intense training, potentially delaying glycogen depletion. One study found that athletes who consumed ketone esters traveled farther in a half-hour than those who consumed carbohydrates or fat.
- Appetite Reduction: Ketones can influence the hypothalamus, a brain region that regulates appetite, potentially leading to reduced hunger and cravings. Studies have shown that ketone supplementation can lower levels of appetite-stimulating hormones like ghrelin and insulin.
- Prevention of Mental Decline: Ketones serve as an alternative fuel source for the brain, particularly during periods of low glucose availability. They may also protect against neurological damage by blocking inflammasomes, which contribute to inflammation in the body. Some studies suggest that ketone supplementation can improve cognitive function in individuals with Alzheimer's disease or mild cognitive impairment.
- Faster Entry into Ketosis: Keto//OS can help individuals reach ketosis more quickly, which can be beneficial for those starting a ketogenic diet or seeking to alleviate "keto flu" symptoms like nausea and fatigue. The combination of BHB and MCT powder in Keto//OS supplements has been shown to effectively raise ketone levels.
Potential Risks and Side Effects
While exogenous ketones offer potential benefits, it's crucial to be aware of potential risks and side effects.
- Digestive Issues: Stomach upset, including diarrhea, pain, and gas, is a common side effect of ketone supplements.
- Bad Breath: Elevated ketone levels can cause bad breath due to the production of acetone.
- Low Blood Sugar: Ketone supplements can lower blood sugar levels, which may be a concern for individuals with diabetes.
- Expense: Keto//OS can be costly, especially if consumed at the recommended dosage.
- Unpleasant Taste: Some users find the taste of Keto//OS to be unpleasant.
- Short-term reduction in endogenous ketones production: After ingesting ketones, your body may shut down ketogenesis (i.e., your natural process of making ketones).
- May trigger disordered eating: Marketing and educational materials promote the need for a quick ketosis fix and seemingly magical solution for fat loss struggles without any legitimate evidence to support their claims. As a result, buying into their supplement system can provoke the very same disordered eating behaviors that we often try to avoid by going low carb.
Keto OS NAT vs. Other Keto//OS Products
Pruvit offers a range of Keto//OS products, including Keto OS NAT and Keto OS PRO. Keto OS NAT stands out due to the addition of C-Med 100®, an ingredient associated with benefits like healthy cell function and DNA repair. Keto OS PRO, on the other hand, contains added protein.

The MLM Structure of Pruvit
Unlike many other supplement companies, Pruvit utilizes a Multi-Level Marketing (MLM) structure. This means that products are primarily sold through distributors who earn commissions on sales and recruitment. Purchasing Pruvit products typically requires a referral link or code, which may influence purchasing decisions.
Perfect Keto as an Alternative
Perfect Keto is another company that offers exogenous ketone supplements. Unlike Pruvit, Perfect Keto does not employ an MLM structure, making its products more accessible through direct purchase. Perfect Keto Base contains 11.3 grams of high-quality BHB per serving and is sweetened with monk fruit and stevia, keto-friendly sweeteners that do not impact blood sugar levels.
Dosage and Use
The typical dosage for Pruvit Keto OS involves mixing one packet with 12 to 16 ounces of cold water. Pruvit recommends one packet a day for therapeutic benefits, and two packets a day for optimal performance.
