Prüvit’s Pure Therapeutic Ketones in KETO//OS NAT need to be bound to something in order for the body to absorb and utilize them. Prüvit uses a combination of the minerals sodium, calcium, and magnesium to bind to BHB ketone salts, and a higher percentage of sodium specifically because sodium is absorbed very rapidly by the body. Those sodium-bound ketones get into the bloodstream faster, and the body can reach a state of ketosis faster! Calcium and magnesium are absorbed at a slower and steadier rate, resulting in the more sustained ketone utilization and benefits your body experiences after drinking KETO//OS NAT.
