Some athletes say that nitric oxide improves the results of weight training.
Advocates say that AAKG increases the body’s production of nitric oxide, a natural blood-flow enhancer. A double-blind trial of AAKG suggested it might improve some measures of strength and power resulting from weight-training.
Typically, 4 grams of AAKG are taken three times a day.
In an eight-week double-blind trial, weight lifters taking 4 grams of AAKG three times a day reported no significant side effects, showed no changes in blood pressure or heart rate, and had no abnormalities on standard blood tests for general health.1 These athletes also reported no undesirable changes in general health, mental health, libido, sleep quality, or other quality of life measures.2 Some doctors believe that people with herpes (either cold sores or genital herpes) should not take arginine supplements, because of the possibility that arginine might stimulate replication of the virus.
No clear interactions between AAKG and other nutrients have been established.
Although the substances that comprise AAKG are present in many foods, the AAKG compound is found only in supplements.
