7 Benefits of Collagen

There are several health benefits that collagen has in our body.

Collagen helps your digestive tract heal quickly and helps your body fix the mucous lining. Glycine, found in collagen, helps decrease inflammation and build new tissue in your digestive tract. Therefore, collagen helps digest food better.

  • Improves Skin

As we age, collagen production declines by roughly 1% per year starting in our early 20s and then bumps up to 30% during menopause. Your skin will gradually begin to deteriorate significantly.

On the good side, collagen helps to improve skin by combating wrinkles and fine lines. Collagen also helps to increase the elasticity and regeneration of skin cells.

  • Joint Pain Relief

As we have said earlier, collagen is found in the cartilage between the joints. When collagen production reduces with age, a condition known as osteoarthritis is formed. It causes stiffness and pain in the joints.

A recent study found that 250 people with osteoarthritis felt better after taking 10g of pure collagen peptides every day.

  • Weight Loss
