SO Science Only Certified Grass-Fed Collagen Peptides. LIAF

What the brand says

Sold as “SO Science Only Certified Grass-Fed Collagen Peptides. LIAF Certified. 40 Servings.”

100% grass-fed. 100% traceable. This formula supports joints, strengthens tissues and nourishes skin, with maximum absorption and effectiveness. What makes our collagen peptides special is that they’re certified grass-fed – fully traceable from pasture to powder. A lot of brands put “grass-fed” on the label, but can’t back it up, or only meet the most minimal requirements to make the claim. But we know every gram of our collagen is from cattle that are grass-fed year round. That’s what we mean when we say “certified.”
