Our Upgraded Collagen is sourced from pasture-raised cows. These cattle are untouched by drugs or hormones and spend their entire lives in the pasture. These cows are fed dried grass (hay/silage) during winter and fresh grass the rest of the year.
And unlike cheaper collagen from gelatin – which gets damaged by heat – Bulletproof Collagen gets enzymatically processed multiple times to leave its nutrition-giving peptides intact.
That makes it highly bioavailable (for maximum nutritional potency) – giving you even more collagen than bone broth.
