Collagen has become one of the most popular wellness supplements and for good reason. As the most abundant protein in the body, collagen plays a vital role in maintaining healthy skin, hair, nails, joints, bones, and connective tissues.
However, not all collagen is created equal. There are several types of collagen, each with unique functions and benefits. Understanding the differences can help you choose the right collagen supplement to support your health and beauty goals.
What Is Collagen?
Collagen is a structural protein that acts as the body's natural support system. It provides strength, elasticity, and resilience to tissues throughout the body.
From our mid-20s onwards, natural collagen production begins to decline. This gradual reduction can contribute to visible signs of ageing, reduced skin elasticity, and changes in joint comfort and mobility.
Collagen supplements can help support your body's collagen levels and overall wellness.
