L-Pyroglutamic Acid


Products Description

Pyroglutamic acid is an amino acid that can be biosynthesized in the body and can also be found in food, such as fruits and vegetables. Pyroglutamic acid has two specific forms, D-pyroglutamic acid and L-pyroglutamic acid.

L-pyroglutamic acid can increase the activity of the neurotransmitter acetylcholine, it’s also widely used in producing gamma-aminobutyric acid (GABA), boosting brain functions such as anxiety reduction, memory recall, learning and mental focus.
