Natural Testosterone & sex drive Support! DAA Caps contain 3.12 grams (3120 mg) of Sodium D-Aspartic Acid per serving.Recent research on Sodium D-Aspartic Acid has shown that it serves as a specialized neurotransmitter in parts of the nervous system involved in hormone production, and has been shown to stimulate the release of LH and GH from the pituitary gland. It has also been shown to have a direct stimulating effect in the testes on testosterone production. A recent human study on D-Aspartic Acid showed that it raised testosterone levels in healthy adult males an average of 42% in as little as 12 days, with some experiencing a boost of over 50% in that same period of time. This study also indicated that testosterone levels were still elevated 3 days after the discontinuation of D-Aspartic Acid, which indicates that it builds up over time, and then slowly decreases after supplementation is stopped. The above study shows for obvious reasons why Sodium D-Aspartic Acid is desirable for athletes and weights trainers looking to build lean muscle and strength. It is important to note that the dosage used in the study was 3.12 grams per day, which is the exact dosage used in Serious Nutrition Solutions DAA Caps.
