Why supplement?
Marked asPrimarySupporting
Promotes gastric acid secretion
Histidine decarboxylase turns it into histamine. Parietal cells use histamine to stimulate acid secretion; mast cells use it to tune local blood flow. Everyday meat, fish, and dairy usually already supply this essential amino acid. People with weak digestion and low stomach acid more often map onto this path.
Supports intramuscular hydrogen-ion buffering
Carnosine in skeletal muscle is a condensation of histidine and β-alanine; the imidazole group buffers hydrogen ions produced during exercise near physiological pH. For people who repeat high-intensity efforts and whose muscles acidify fast, histidine supply is one limit on the carnosine pool.
How to take it?
