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.

Vitamin B12

Vitamin B12 deficiencies are associated with skin lesions and hyperpigmentation. Patients with low levels of this vitamin may notice premature graying of the hair and premature hair loss. If a vitamin B12 deficiency is present, patients may develop ridges in the fingernails. The lunula (the white half-moon at the cuticle) may be absent as well. Studies show that vitamin B12 supplements may help improve skin, nail, and hair health in individuals with low vitamin B12. In fact, case studies have shown that several different skin lesions completely disappear once the patient's vitamin B12 level reaches a healthy range.

Patients can have their vitamin B12 levels checked with a simple blood test. If the patient has a severe deficiency, vitamin B12 injections may be necessary. Doctors may prescribe high-dose oral supplements for several weeks. Although supplementation is critical for patients with low vitamin B12, research suggests that individuals who have vitamin B12 levels in the healthy range are unlikely to benefit from supplements.
