Nails Keep Breaking?

Biotin to the Rescue

Hochman LG, et al., Abstract

A recent study from Switzerland demonstrated a 25 percent increase in nail plate thickness in patients with brittle nails who received biotin supplementation. Analysis of all visits to a nail consultation practice over a six-month period revealed forty-four patients with this condition who had been prescribed the B-complex vitamin biotin. Of these, thirty-five who took daily supplementation were subjectively evaluated. Twenty-two of thirty-five (63 percent) showed clinical improvement and thirteen (37 percent) reported no change in their condition. The results of this small, retrospective study suggest a positive response to biotin in the treatment of brittle nails in some patients.


Biotin, one of the B Complex vitamins, is also known as Vitamin H. The entire family of B Vitamins helps the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. Biotin also plays a role in the metabolism of fats and protein. and helps promote healthy skin, hair, eyes, and liver. According to the Linus Pauling Institute, “Research indicates that biotin is broken down more rapidly during pregnancy and that biotin nutritional status declines during the course of pregnancy… and three uncontrolled trials examining the effects of biotin supplementation (2.5 mg/day for up to six months) in women with brittle fingernails have been published. In two of the trials, subjective evidence of clinical improvement was reported in 67-91% of the participants available for follow-up at the end of the treatment period.” The best food sources of biotin are egg yolk, liver and yeast.
