What are Ketone Supplements?

Ketone supplements are products containing the ketone betahydroxybutyrate which quickly increases ketone levels.  Exogenous ketone supplements (originating outside the body) were only available to researchers until early 2016.  Before that, we could only increase ketone levels within our body when fat breaks down during fasting/starvation, a “keto” (ketogenic) diet or by taking coconut oil, palm kernel or MCT oil which is extracted from coconut or palm kernel oil.  Some people experience diarrhea with even small amounts of these oils, so taking ketone salts could help with that. Technological advances have made ketones available as salts so that they can be taken as a drink.  This new technology developed at University of South Florida makes it possible for us to drink ketones as salts to increase ketone levels to a therapeutic level within 30 mins with little, if any, intestinal discomfort.

I have been taking coconut and MCT oil for more than 10 years and now personally benefit from taking Pruvit ketone salts on a daily basis as well.  I travel often and take MCT//143, my MCT oil, coconut oil and phosphatidylcholine mixture is available through Pruvit in convenient 15 ml sachets. I’m extremely excited and passionate about the advancements in the exogenous ketone supplementation, the care taken to balance the salts (sodium, potassium, calcium and magnesium) and create new products–cold drinks, teas, broths in many flavors with and without caffeine.

For infants, children, elderly adults and people with medical conditions it is important to talk with your physician before beginning any ketogenic diet or ketone supplement.  I do not recommend ketogenic diets or ketone supplements for pregnant and breastfeeding women, since women in these conditions are naturally already in ketosis and could develop ketoacidosis; safety studies have not been conducted in pregnancy or breastfeeding.  While coconut oil and MCT oil are generally recognized as safe, the FDA does not recognize ketone salts as effective for any specific health claim.
