Episode 3

Every drugstore and supermarket has them on their shelves these days: expensive collagen powders, pills, or creams. They're for people looking for wrinkle-free skin or supple joints. But do these products live up to their promises? We'll try collagen powder for a month and analyze the results with a dermatologist. They'll also warn about the risks: the collagen powders are almost always derived from animal sources, such as cartilage, skin, and bones from cows, or fish scales, and may therefore contain heavy metals. We'll also review scientific studies and explore alternatives to collagen products.
