You Asked: Should I Eat Collagen Powder?
The word “collagen” comes from the Greek word for glue, and that’s a helpful way to think about the role collagen plays in your physical health. In your skeleton, tendons, muscles, skin and even your teeth, collagen is a structural protein that binds cells and tissues together while helping them maintain shape and integrity.
But your body produces less and less collagen as you age. And some supplement- and food-makers are marketing collagen products as a way to boost your body’s levels of it.
“Collagen is basically the sale of amino acids,” says Dr. Mark Moyad, director of preventative and alternative medicine at the University of Michigan, and author of The Supplement Handbook. Amino acids are protein’s building blocks, and supplements and foods that have collagen contain chains of collagen-derived protein amino acids—or sometimes just the amino acids themselves, separated from their bonds, Moyad says. There are different types of collagen; some are derived from animal bones or skin, and others from animal cartilage.
