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 (for Relaxation)
Simplest amino acid with profound calming and sleep effects. Lowers body temperature.
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.
