Biotin is a necessary vitamin for the growth and health of your body. It aids in the converting of fatty acids and glucose into fuel for the energy you need to function on a daily basis. If you feel run down you may be low on this B vitamin.
It also metabolizes amino acids and carbohydrates and helps to produce certain enzymes that your body needs for normal functioning. It plays a part in keeping your sweat glands, nerve tissues, and marrow healthy and working efficiently.
Biotin is taken as a supplement for people who have a biotin deficiency. Symptoms can range from dry skin and brittle hair to nausea, depression and muscular pain. Although a biotin deficiency is pretty rare since it is only needed in small amounts and is found in a wide variety of foods, people take biotin for other reasons such as for hair loss, brittle nails, diabetes, high cholesterol and sometimes depression.
