What is biotin?

Biotin (vitamin B7) is a water-soluble vitamin found in a variety of foods or made naturally by the bacteria in our bowel. As it’s water-soluble the body doesn’t store this vitamin, and any excess is passed from your body through your urine. Biotin’s main function is to help break down the proteins, fats and carbohydrates from the foods we eat and convert this into energy. Biotin also plays an important role in gene regulation, cell signalling and mucus production.

Biotin can be found in a number of natural food sources, including:

  • Salmon
  • Cooked eggs
  • Beef liver
  • Seeds and nuts
  • Pork
  • Sweet potato

How biotin can improve hair growth

Our hair and nails are made from protein know as keratin which we can get from the foods we eat. Biotin's involvement in protein synthesis and keratin (the key structural material of hair) production allows this vitamin to contribute to healthy nail and hair growth. Whilst biotin deficiency is rare, symptoms do include thinning hair and brittle nails.

However, according to studies carried out to test the effect of biotin supplements on hair growth, results appear to show that little change occurs in healthy individuals. Only those who are low in this vitamin will find any improvements from taking supplements.

Several factors can make you more susceptible to biotin deficiency. According to the National Institute of Health, the following groups are at a higher risk:

These groups are at higher risk because they are less able to absorb vitamins and minerals from their diet.

Biotin for beard growth

As biotin is known to contribute to the production of keratin, it’s often advertised as a supplement that may contribute to a thicker beard. Some case studies do exist that appear to indicate that biotin may help support hair growth, however, evidence of noticeable change tends to only be seen in individuals who are deficient in this vitamin.

What might be causing my hair loss?

Hair loss is extremely common and is often not something that should be a cause for concern. According to the NHS, there can be temporary causes for hair loss.

These include:

  • Emotional stress
  • Illness
  • Cancer treatment
  • Iron deficiency
  • Weight loss

Other causes of hair loss may be down to genetics and can be more permanent. If you’re worried about hair loss your GP will be able to help with advice and support. Alternatively, you can visit our hair loss clinic over at Online Doctor to have a free online consultation with an experienced clinician.

Support groups are also available for those wishing to speak to someone. 

Biotin supplements for hair loss

Biotin supplements are available for those who would like to support their body in every way they can alongside a varied diet and healthy lifestyle.
