Correxiko’s collagen powder is hydrolysed, meaning that it’s broken down into its constituent amino acids, which are the essential building material to renew cells throughout the body. The powder can be kept on your kitchen counter as a reminder to take it every day. There is no need for refrigeration. Liquid collagen, however, usually needs to be kept in the fridge, and this sometimes means that it gets forgotten about. We recommend using collagen powder or capsules as neither require refrigeration and research has shown that it’s important to take collagen everyday in order to make the most of the beneficial effects for your skin, hair, nails, eyes, teeth, cartilage, ligaments, tendons, muscles, joints, bones, internal organs, blood vessels, and your immune system.
