There are 16 different types of collagen, but if you want healthy hair, skin, nails, and bones, there are two types that work best. Type I collagen is the most common form of collagen in the human body. Supplementing this collagen can have a dramatic effect on the health of the hair, skin, and nails. Ingestion of type I collagen can heal the skin by promoting density of collagen fibrils and fibroblasts, thus stimulating collagen production. Type III collagen is the second most abundant collagen in the body. This type of collagen is also found in the skin and is responsible for its elasticity. Type III collagen is also a building block for the extracellular matrix the forms the structure of blood vessels and organs. Divine Health’s collagen capsules contain both type I and type II collagen to make sure your body has the building blocks necessary so you can look, feel, and perform your best!
