Possible Deficiencies
A deficiency of AAKG has not been reported.
Side Effects
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.5 These athletes also reported no undesirable changes in general health, mental health, libido, sleep quality, or other quality of life measures.6 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.
