Principal Proposed Uses
Other Proposed Uses
Inosine is an important chemical found throughout the body. It plays many roles, one of which is helping to make ATP (adenosine triphosphate), the body's main form of usable energy. Based primarily on this fact, inosine supplements have been proposed as an energy-booster for athletes, as well as a treatment for various heart conditions.
Inosine is not an essential nutrient. However, brewer’s yeast and organ meats, such as liver and kidney, contain considerable amounts. Inosine is also available in purified form.
When used as a sports supplement, a typical dosage of inosine is 5 to 6 g daily (see Safety Issues).
Therapeutic Uses Inosine has been proposed as a treatment for various forms of heart disease, from irregular heartbeat to recovery from heart attacks . 1 However, the evidence that it offers any benefit to the heart remains far too preliminary to rely upon at all. Inosine is better known as a performance enhancer for athletes, although most of the available evidence suggests that it doesn't work for this purpose. 2–6 Inosine has also been suggested as a possible treatment for Tourette’s syndrome, a neurological disorder. 7
