Biotin supplements are used to prevent or treat biotin deficiency.
Vitamins are compounds that you must have for growth and health. They are needed in only small amounts and are usually available in the foods that you eat. Biotin is necessary for formation of fatty acids and glucose, which are used as fuels by the body. It is also important for the metabolism of amino acids and carbohydrates.
A lack of biotin is rare. However, if it occurs it may lead to skin rash, loss of hair, high blood levels of cholesterol, and heart problems.
Some conditions may increase your need for biotin. These include:
Increased need for biotin should be determined by your health care professional.
Claims that biotin supplements are effective in the treatment of acne, eczema (a type of skin disorder), or hair loss have not been proven.
Biotin supplements are available without a prescription.
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
Biotin is found in various foods, including liver, cauliflower, salmon, carrots, bananas, soy flour, cereals, and yeast. Biotin content of food is reduced by cooking and preserving.
Vitamins alone will not take the place of a good diet and will not provide energy. Your body needs other substances found in food, such as protein, minerals, carbohydrates, and fat. Vitamins themselves cannot work without the presence of other foods.
The daily amount of biotin needed is defined in several different ways.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
