Collagen is a protein responsible for healthy joints and skin elasticity. Collagen is found in our bones, muscle and blood, it makes up three quarters of our skin and a third of the protein in our bodies.
Over time, our collagen levels start to break down and it becomes harder for our bodies to produce more. This is why many people choose to take collagen supplements - to help boost their body's collagen levels.
Benefits of taking collagen have been shown to include:
Skin elasticity and hydration: Oral collagen supplementation has been shown to improve skin hydration and elasticity for people as they age, as well as helping to lessen the appearance of fine lines and wrinkles.
Thicker hair: While more men go bald, many women also experience hair loss or thinning as they age. In one study, a group of women with thinning hair saw significant increases in their hair's quantity, scalp coverage, and thickness while taking daily collagen supplements.
Healthier nails: Some people's nails break more easily than others and don't grow so fast. One study in a group of women showed faster nail growth and fewer broker or chipped nails after only four weeks of daily collagen supplementation.
Stronger bones: As we age, our bones become less dense and more brittle, breaking more easily and taking longer to heal. Studies have shown that daily collagen supplementation can help make your bones denser, slowing the ageing process that makes them brittle and helping your body to produce new bone.
Reduced osteoarthritis pain: For people with knee osteoarthritis, oral collagen supplements may act as a mild pain reliever and improve joint function.
