Seniors should consult their doctors before taking Nail-ex or any other dietary supplement to make sure that Nail-ex is safe and recommended for them and won't interact with medications they are taking.

Nail-ex supplements contain 2,500 micrograms (mcg) of biotin, a B vitamin that is present naturally in the body and in many foods, including eggs, whole grains, nuts, bananas, soybeans and other legumes. The National Academy of Sciences has determined that 30 mcg is an adequate daily intake of biotin for adults; most people get this much in their diets. However, biotin supplements may be recommended for adults who are deficient in biotin.

There is preliminary research that biotin may help strengthen brittle nails, but the evidence is weak. Some studies have also suggested that biotin can improve symptoms in people who have diabetic peripheral neuropathy (tingling numbness and pain in the arms, hands, legs or feet). When combined with chromium, biotin also may help people with diabetes control their blood sugar. But more study is needed to confirm these benefits.
