Biotin benefits

Biotin, also known as vitamin B7, is a water-soluble member of the B-complex vitamins. Ranging from hair growth to metabolism support, the benefits of biotin are felt all over the body. Here’s everything you need to know about this essential nutrient.

What Is Biotin?

Biotin is an important vitamin most commonly known for its effects on hair and skin. (1) It’s found in many foods including eggs, nuts and sweet potatoes. If you struggle to maintain a healthy balanced diet, a biotin supplement can help to boost your daily intake.

Alongside playing a major role in metabolism, biotin is well-known as a beauty vitamin. Biotin is involved in the production of fatty acids that nourish the skin and help it to appear smooth and hydrated. 2

Furthermore, biotin contributes to healthy mucous membranes. (3) Mucous membranes line cavities and areas of the body that connect the inside to the outside. These include your ears, nose, throat and digestive tract. Keeping these areas healthy is vital for overall health, as well as for clearer skin. When mucous membranes are unhealthy or damaged, this may appear as blisters or sores, for example around the mouth or eyes.

For hair, biotin has been found to increase keratin production and stimulate the growth of hair follicles. (4) Keratin is the protein that forms the building blocks of our hair, skin and nails. If you’re experiencing thinner hair or hair loss, biotin may assist with re-growth, and promoting stronger hair.

Likewise, biotin may strengthen the keratin in your nails, improving their thickness and preventing breakage. 5

More Biotin Benefits

Biotin may have a large number of beauty benefits, but research suggests that the impacts of this vital vitamin extend even further. It supports both psychological and nervous system functions. (6) Together with other B-vitamins, biotin has been suggested to improve memory and defend against cognitive decline and neurodegenerative diseases, such as Alzheimer’s disease. 7

Who Is At Higher Risk Of Biotin Deficiency?

As a water-soluble vitamin, biotin is not stored in the body. Excess biotin is transported out of the body during urination.

While biotin deficiency is rare, certain risk factors can increase the likelihood. These risk factors include pregnancy, breastfeeding, following a vegan diet and having a health condition that affects how well nutrients are absorbed. With deficiency comes undesirable symptoms, such as thinning of the hair, a red rash, brittle nails and reduced energy levels. Therefore, consuming enough biotin on a daily basis is vital for keeping us feeling and looking our best.

How Much Biotin Should I Be Getting?

There is no set recommended daily amount of biotin we should be aiming for. However, suggestions range between 10-30µg, with increased amounts recommended for individuals who are pregnant or breastfeeding.
