Editor Quote: "Not only are collagen peptides packed with protein, but they're also flavorless. I can add it to pretty much anything and can't taste it. I'll sometimes add a scoop to a cup of hot herbal tea, and it doesn't interfere with the flavor." — Christina Stiehl, former senior editor, Fitness
