Precursor of nitric oxide, creatine and polyamines

Arginine is the precursor to nitric oxide (NO), creatine and polyamines. Arginine is a semi-essential, or conditional, amino acid. Adults can synthesize arginine themselves from other amino acids. However, in certain circumstances, arginine becomes essential. Biosynthesis in these times is too low to meet the daily requirement. Athletes often choose L-arginine supplement. Increased concentrations of arginine and silicon set in 15 minutes after ingestion and last up to 6 hours.
