At What Age Do I Need to Start Taking Collagen Supplements?
Collagen makes up approximately 30% of your total body protein and 75% of your skin. It gives your skin elasticity while keeping it firm, makes your hair shiny, and keeps your nails strong1. There are more than 28 different types of collagen, but the three most abundant are Types I, II, and III2: Type I: The most abundant form of collagen that is found in tendons and throughout the body. It's a key building block for hair, skin, nail, blood vessel, and teeth health. Type II: This type of collagen structure is found in joint cartilage. Type III: This is the second most abundant form of collagen and is found in association with Type I collagen. Your body naturally produces the collagen it needs, but production starts to decline around the age of 25 by about 1-2% each year and is not replenished3. Most of the changes in your skin caused by aging happen in the dermis layer, which loses about 20-80% of its thickness. Once you reach the age of 30, the effects of collagen loss can become more noticeable. Some of the signs of collagen depletion include:
- Loss of skin elasticity
- Increase of wrinkles
- Loss of volume
- Changes in the color and texture of the skin
