The Collagen Protocol: What 20 g/day actually does.

Hydrolyzed collagen peptides are absorbed as di- and tri-peptides via intestinal peptide transporters, arriving intact at the bloodstream. That absorption profile is the mechanism behind the joint, skin, and connective-tissue effects seen in recent randomized controlled trials.

Doses in the published literature that produced measurable outcomes cluster in the 10–20 g/day range, taken consistently over 8–24 weeks. Under-dosing is one of the most common failure modes in the supplement market — a 5 g scoop rarely moves the needle.

Our Grass-Fed Collagen Peptides deliver 18 g per serving, inside that clinically effective window, from pasture-raised bovine sources audited for quality and sustainability.
