Inosine

Inosine is not an amino acid but is classified as a nucleoside, one of the basic compounds comprising cells. It is a precursor to adenosine, an important energy molecule, and plays many supportive roles in the body, including releasing insulin, facilitating the use of carbohydrate by the heart, and, potentially, participating in oxygen metabolism and protein synthesis.

What it is

Inosine is a nucleoside, one of the basic substances of which cells are comprised. It is a precursor to adenosine, an important molecule that plays a role in energy production and metabolism. It is also a precursor to uric acid, a naturally occurring substance that is believed to neutralize some free radicals and may prevent the development of multiple sclerosis.

Benefits

Inosine is believed to play a supportive role in many bodily functions, including the release of insulin, protein synthesis, and oxygen metabolism. Studies conducted in Europe suggest that inosine may enhance oxygen delivery to the muscles, which can result in increased endurance and may be of benefit to athletes. Inosine may also work in conjunction with other chemicals to remove a buildup of lactic acid in the blood, improving energy production and exercise performance.

Dosage

The amount of inosine to be taken depends on the condition being treated. Generally, some practitioners will recommend 500-2,000 milligrams of inosine in supplement form, taken 30 minutes before exercising. Some studies have used doses ranging up to 6 grams per day, taken for several weeks.
