All About Collagen
Collagen supplements have grown in popularity in recent years as consumers look for natural ways to improve skin, hair, joint and overall health. But what is collagen, why do our bodies need it and what is the actual evidence behind the claims?
What is collagen?
Collagen is the most abundant protein in the human body, making up around 75% of our skin and about a third of our total body protein. It acts as the “scaffolding” that keeps skin firm, plump and smooth, while also supporting healthy joints, bones, hair and nails. Collagen supplements replenish the body's collagen levels from within to support the body's structure, strength and natural glow.
What does collagen do?
Collagen is a true multitasker when it comes to health and beauty. Supplementing regularly may help to:
- Improve skin elasticity, hydration, and radiance
- Reduce fine lines, wrinkles, cellulite, and stretch marks
- Support stronger hair and nails
- Protect bones and joints
- Aid muscle repair and wound healing
- Promote healthy blood sugar levels and calm gut inflammation
- Encourage restful sleep and ease menopausal symptoms, such as hot flushes and mood swings
By replenishing collagen levels from within, you’re supporting your body’s structure, strength, and natural glow.
