What is D-aspartic acid?

    Last Updated: October 25, 2023

    D-aspartic acid and L-aspartic acid are the two naturally occurring forms of the amino acid aspartic acid.[1] Both are synthesized in the human body, they are also obtained through the diet via any dietary protein source.[1][2] While L-aspartic acid is used as a protein building block, D-aspartic acid is not.[1] Instead, D-aspartic acid has direct effects on the central nervous system and endocrine tissues.[1][3][4] This is why D-aspartic acid is also sold as a dietary supplement.
