Common Names: DAA, Aspartic Acid D-form, D-Aspartate
Scientific Names: 2-Aminobutanedioic acid
D-Aspartic Acid (DAA) is a nonessential amino acid synthesized in the body and obtained through dietary sources particularly in high-protein sources like meat and eggs. It holds significance in reproductive function and fertility. Alongside its counterpart, L-aspartic acid, both forms are naturally occurring and synthesized in the human body. While L-aspartic acid serves as a protein building block, D-aspartic acid, uniquely, exerts direct effects on the central nervous system and endocrine tissues. Despite marketing claims suggesting its role in increasing muscle mass and strength, especially in combination with resistance training, there is limited evidence supporting such assertions in humans. Human trials have even reported small reductions in testosterone levels, contrary to the observed effects in rodents. D-Aspartic Acid is also identified as one of the two D-amino acids commonly found in mammals, primarily playing a role as a neurotransmitter or neuromodulator and participating in the formation of certain peptides.
The typical recommended dosage for D-Aspartic Acid (DAA) varies, but a common range for adults is around 2 to 3 grams per day. However, it's important to note that individual responses to DAA supplementation can differ, and the optimal dosage may depend on factors such as age, weight, and overall health. It's crucial for individuals considering DAA supplementation to follow established guidelines and consult with healthcare professionals for personalized advice. Moreover, due to limited and inconclusive evidence on its efficacy and potential side effects, careful consideration and moderation are advisable when incorporating DAA into a supplement regimen.
