Amino acid supplements for performance, recovery, mood, and sleep — including L-theanine, creatine, glutamine, GABA, and more.
Amino acids are the building blocks of proteins and neurotransmitters. While you get many from dietary protein, targeted amino acid supplementation can provide benefits that food alone can’t easily achieve — like L-theanine’s calm focus, creatine’s cognitive and muscle support, or GABA’s relaxation effects.
Many amino acids are best absorbed on an empty stomach, away from protein-containing meals which compete for the same transport pathways.
The simplest amino acid that supports sleep quality, collagen synthesis, and immune function
The glutathione precursor that rebuilds antioxidant defenses and supports respiratory and immune health
The cardiac and neurological amino acid that supports heart health, athletic performance, and cellular function
The methyl donor that supports cardiovascular health, detoxification, and cellular energy production
