More in Amino Acid

Other ingredients in the Amino Acid category.

5-HTP

Direct serotonin precursor, one step closer than tryptophan. More potent for mood and appetite but requires more caution.

Glycine

Simplest amino acid with diverse roles in collagen synthesis, sleep quality, neurotransmission, and detoxification.

Glycine (Longevity Dose)

Simplest amino acid with emerging longevity benefits at higher doses. Supports glutathione, collagen, sleep, and may mimic methionine restriction.

Hydrolyzed Whey Protein

Pre-digested whey protein with faster absorption than isolate or concentrate, ideal for post-workout recovery and those with digestive sensitivities.

L Carnitine

L-carnitine is a naturally occurring compound synthesized from amino acids that plays a crucial role in transporting long-chain fatty acids into mitochondria for energy production. Evidence supports modest benefits for exercise performance and recovery in carnitine-deficient individuals, though benefits in healthy populations are limited.

L-Arginine

A conditionally essential amino acid that serves as a precursor to nitric oxide, supporting vasodilation and blood flow. Most evidence supports benefits for endothelial function and exercise performance, though clinical results are mixed.
