D-Aspartic Acid
BulkSupplements.com
Overview
While D-aspartic acid is marketed to enhance testosterone levels and muscle performance, the existing body of human clinical trials does not support these claims. Research suggests potential mechanisms for hormone regulation and neurotransmitter activity, but these effects have not been robustly demonstrated in human trials. The current evidence suggests, with low confidence, that D-aspartic acid supplementation has no significant effect on strength, muscle mass, athletic performance or overall health metrics.
