Guide To Common Supplements For The Hair, Skin, And Nails

Biotin

Biotin (vitamin B7) is a coenzyme used in the metabolism of glucose, amino acids, and fatty acids. Several studies suggest that biotin may help promote the growth and health of the hair. In research studies, patients who took biotin each day reported perceived improvements in hair thickness, volume, and scalp coverage after three months. After six months of treatment, the study participants felt that their hair was shinier. Biotin can help reduce hair loss. It is also recommended as a treatment for brittle nails. In terms of skin health, biotin may be useful in preventing and treating dry or cracked skin, fungal skin infections, acne, and rashes.

Although biotin is found in many topical treatments, experts believe that it is most effective when taken orally. Certain antibiotics and anti-seizure medications can cause biotin deficiencies. Patients with celiac disease are at an increased risk of this deficiency as well. These individuals may want to talk with their doctor about the risks and benefits of taking a biotin supplement. Generally, doctors recommend a maximum biotin dose of three thousand micrograms per day.
