L-Arginine is a protein amino acid that is present in all life forms on the earth. It is an essential amino acid that is needed for normal body function and healing.
L-Arginine is used to make nitric oxide, a compound in the body that relaxes blood vessels.
Preliminary studies have found that L-Arginine may help with conditions that improve when blood vessels are relaxed (called vasodilatation).

Gamma-aminobutyric acid, abbreviated as GABA, is an amino acid that is produced in the brain. It is formed by glutamic acid in the body with the help of vitamin B6, and prevents nerve cells from firing too much and, thus, having a claming effect. As such, GABA serves as a neurotransmitter.

BETA-X contains a special patented beta-alanine substrate in an innovative time released formulation that is designed to provide 24-hour muscle saturation of what could possibly be the most important performance supplement in 15 years – and quite possibly ever. BETA-X contains a naturally occurring amino acid that is the precursor to a critically important di-peptide called carnosine. Carnosine is a substance formed from beta-alanine that is naturally occurring in muscle tissue – primarily in fast twitch muscle fibers. Carnosine’s primary function in muscle is to buffer hydrogen ions (H+).
