L-Arginine L-Pyroglutamate (or Arginine Pyroglutamate) is a complex of L-arginine and L-pyroglutamic acid molecularly bonded together. This amino acid complex has synergistic effects of L-arginine and L-pyroglutamic acid. L-Arginine is the precursor of nitric oxide (NO). Nitric oxide is produced from L-arginine by all tissues of the body and plays important roles in the cardiovascular system, immune system and nervous system. L-Pyroglutamic acid is naturally found in many foods and proposed to be associated with activity of the neurotransmitter acetylcholine and GABA. L-Pyroglutamic acid can improves learning and memory capacities in animal testing[1]. L-Arginine L-Pyroglutamate can cross the blood brain barrier and enter into the brain to improve brain blood flow and cognitive functions.
