OKG is not found in food, although its two building blocks are. Animal studies suggest that OKG may prevent the breakdown of muscle, which has led to the suggestion that it may be helpful for athletes in training. The amino acids that make up OKG are found in high-protein foods such as meat, fish, and dairy, but OKG itself is not found in foods.
Supplements are available in tablet or pill form.
Therapeutic Uses OKG is widely used by athletes in the hope that it will increase their muscle development in training. However, there is practically no foundation for this belief, other than two rather theoretical studies in rats. 1,2 Safety Issues OKG appears to be safe. However, as with all supplements used in multigram doses, it is important to purchase a reputable product, because a contaminant present even in small percentages could add up to a real problem. The maximum safe dosages for young children, women who are pregnant or nursing, or those with serious liver or kidney disease have not been established.
