Nutricost Performance D-Aspartic Acid, or Nutricost D-Aspartic Acid (DAA) Capsules 2000mg Per Serving
Nutricost
Overview
This supplement provides D-Aspartic Acid at a dose (2000mg) that has been used in human studies. However, the current scientific evidence in humans largely does not support the claims of increased testosterone, muscle mass, or strength, which are often associated with DAA. The observed benefits in rodent or cell culture studies do not consistently translate to human physiology.
