Collagen is the most abundant protein in the human body, making up approximately 25%-35% of all proteins. It plays a crucial role in maintaining skin, hair, nail, and joint health. Here are some of the main functions of collagen:

1. *Skin elasticity and hydration*: Collagen helps maintain skin elasticity, firmness, and hydration, reducing the appearance of fine lines and wrinkles.
2. *Joint health*: Collagen is a key component of joint cartilage, helping to cushion and absorb shock, reducing joint pain and inflammation.
3. *Hair and nail growth*: Collagen promotes healthy hair and nail growth, improving strength and texture.
4. *Gut health*: Collagen helps maintain a healthy gut lining, supporting digestion and preventing leaky gut syndrome.
5. *Muscle mass and strength*: Collagen helps build and repair muscle tissue, improving muscle mass and strength.
6. *Bone density*: Collagen helps maintain bone density, reducing the risk of osteoporosis and fractures.
7. *Cellulite reduction*: Collagen helps improve skin texture, reducing the appearance of cellulite.
8. *Wound healing*: Collagen promotes wound healing by supporting tissue repair and regeneration.

As we age, collagen production naturally decreases, leading to wrinkles, joint pain, and other signs of aging. Consuming collagen supplements or foods rich in collagen (like vitamin C, vitamin E, and omega-3 fatty acids) can help stimulate collagen production and support overall health.
