Expert Positions
The Verdict
All 5 experts recognize glycine's value, though with varying emphasis. Attia personally supplements with glycine nightly for sleep. Johnson includes glycine in his Blueprint longevity stack as a daily staple. Huberman lists glycine as an optional sleep supplement alongside GABA and myo-inositol. Patrick highlights glycine through collagen peptides for connective tissue repair and wound healing. Hyman recommends glycine for sleep quality and nervous system relaxation.
Where They Disagree
Attia and Johnson actively supplement with glycine as a standalone ingredient, while Huberman considers it optional and secondary to his core sleep stack of magnesium threonate, apigenin, and theanine.
Patrick discusses glycine primarily through the lens of collagen peptides and connective tissue rather than as a standalone sleep supplement, while Attia and Hyman emphasize its direct sleep benefits.
