Do Collagen Supplements REALLY Make You Look Younger?

Shots, powders, drinks, pills, collagen is everywhere! In fact it’s been estimated that the collagen industry is set to be worth approximately £5 billion by 2020, but is there really any science to support the hype?

Collagen is a protein made up of amino acids. It’s the structural component of skin and as we age production declines which can lead to wrinkle formation and sagging skin.

Whilst delaying collagen breakdown may reduce skin ageing, there is no robust evidence to link collagen consumption with increased collagen in the skin. In theory, it makes sense, but there is no concrete proof for this. As collagen is a protein, it’s likely to break down into amino acids within the body via digestion, and then used wherever required but not necessarily to rebuild collagen within the skin.


On the other hand, vitamin C is a critical nutrient required for collagen production. Vitamin C is an antioxidant with high concentrations being found within the skin. This nutrient may help to protect against environmental factors which can speed up the ageing process such as sun damage.

Whilst there is no clear evidence or consensus of the optimal dose of vitamin C for slowing down the signs of ageing, regular consumption of vitamin C rich foods such as oranges, strawberries, broccoli, bell peppers, kiwi and even kale are all essential to long-term health and should not be forgotten within the diet.
