Editor Quote: "I love the collagen powder for its ability to add a hearty dose of protein to anything I'm eating or drinking — it transforms a black coffee or low-protein veggie soup into something that's more satiating and protein-packed...Depending on how much protein I need, I add one or two scoops to coffee, soups, pasta sauces, oatmeal, or smoothies." - Christina Stiehl, former senior editor, Fitness
