Both collagen and biotin play important roles in the health of the skin and hair.
Can taking collagen or biotin improve the appearance of your skin and hair? We don’t know for sure, but emerging research suggests that both may be helpful.
However, biotin is a vitamin that the human body cannot make on its own – people must get it from food or supplements.
Is collagen or biotin better for skin and hair?
Building the skin and hair is a complicated process, requiring many components to work together. Collagen and biotin are both important nutrients that may assist with these processes.
Collagen, a protein that helps form the extracellular matrix, gives skin its shape. The body naturally produces collagen and slows collagen production with age.
Biotin is a B vitamin that one cannot make on their own, yet it is essential for skin, hair and nails health. Some people take collagen, biotin or both as supplements to improve skin firmness and elasticity.
Biotin (vitamin B7) and collagen are both used to help support the skin, hair and nails, but they have different functions. Collagen is a protein that keeps the skin strong and elastic. As a person ages, their production of collagen slows down so they produce less and less. This results in thinner skin, wrinkles, delayed wound healing and more. Biotin is a water-soluble vitamin that helps your body turn food into energy. It is an essential nutrient but one you need to get from food or supplements because your body does not produce it on its own.
Which is better for hair?
People who take biotin supplements may notice that their hair gets temporarily thicker and stronger.
Biotin can help your hair grow, but do not expect wonders. If you take it daily, you may notice a difference in terms of the thickness of your hair and reduction in hair loss. It also may work to help regrow hair.
Supplementing with biotin for skin and hair may improve the thickness and appearance of your skin, and possibly help regrow hair.
Which is better for skin?
A systematic review of some studies on oral collagen supplements suggests that collagen may improve skin health. The review included 11 studies with 805 participants.
While both biotin and collagen help improve the health of your skin, there is more evidence to support that collagen has a positive effect on skin health. If you have a biotin deficiency, taking biotin can be beneficial to your skin and hair. Otherwise, it is best to try collagen for overall skin health, because there are more studies to support this.
Taking collagen can help fill in the wrinkles and furrows by forming stronger new skin. It can also improve skin elasticity, which means it’ll be more difficult for deeper wrinkles to form.
Food high in biotin and collagen
The best way to get enough sources of biotin is to include a wide variety of foods in your diet. Biotin-rich food sources include eggs, meat and fish, such as salmon. You can also find biotin in whole-wheat bread and cheese, apples, plain yogurt and almonds.
Some animal products contain collagen, such as chicken, fish or bone broth.
Eat foods containing collagen and biotin daily to help improve your skin, hair, nails and joints.
Who may benefit from a supplement with biotin and/or collagen
If you are a vegetarian and do not consume any animal products, or you may have difficulties absorbing nutrients, you may be at risk for low levels of biotin.
Biotin and collagen both play important roles in skin and hair health. Biotin deficiency can cause rashes, hair loss and brittle nails, while collagen loss occurs naturally with age and causes a loss of skin elasticity, density and hydration. Whether collagen or biotin is better for a person will depend on their individual circumstances, as advised by your doctor.
