Grass fed collagen? How the hell does that work?
It's collagen from a grass-fed cow... just like humans, cows are healthier and have a better mix of amino acids if they're not fed a funky diet that they aren't built to digest.
I can buy collagen in bulk (powdered bone broth) but it's damned expensive, something like $50 for a 1 pound can, only 20-40 servings in the can.
