Myvitamins Collagen Powder is a blend of type I and III collagen, essential proteins for muscles, bones, and joints. As collagen levels naturally decline with age, this convenient powder supplement helps to support and maintain your collagen levels. Rich in protein, this low-fat powder is a perfect addition to your daily routine, aiding in the growth and maintenance of muscle mass (1). Add it to your drinks, shakes, or bakes for an easy boost of collagen. References: Protein contributes to the maintenance and growth of muscle mass.
