Glycine and Magnesium
A sleep pairing with a built-in shortcut: magnesium glycinate is magnesium bound to glycine, so that form already delivers both. A standalone 3 g dose before bed (the amount sleep studies used) tops up the glycine, lowering core body temperature while magnesium relaxes muscles and calms the nervous system.
Glycine
A calming amino acid for sleep, collagen, and metabolic health.
Magnesium
A master mineral involved in 300+ enzyme reactions.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.

Related pairings
Glycine + NAC
NAC provides cysteine while glycine provides another rate-limiting precursor; together they are more effective at raising glutathione than either alone (GlyNAC protocol).
Collagen + Glycine
Glycine makes up about a third of collagen, so supplementing it provides raw material that collagen synthesis depends on.
Creatine + Glycine
Glycine is one of the three amino acids the body uses to synthesise creatine endogenously.
L-Glutamine + Glycine
Both are conditionally essential under stress and support gut and immune function through complementary pathways.
