L-Pyroglutamic Acid


L-Pyroglutamic Acid is an essential amino acid crucial to maintaining your health. Essential means that your body cant manufacture that amino acid by itself; you have to get it from foods or supplements.

L-Pyroglutamic Acid is a catalyst in the creation of tyrosine, which processes hormones. It also aids in the formation of neurotransmitters like dopamine, epinephrine and norepinephrine. In addition to its extensive role within the body, L-Pyroglutamic Acid is an effective supplement for overall health and well-being.
