What is Biotin?

Biotin is a form of vitamin B found in foods. Biotin helps the body break down fats, carbohydrates, and other substances.

Biotin has been used in alternative medicine as a likely effective aid in treating or preventing Biotin deficiency. Biotin deficiency can be caused by malnutrition, rapid weight loss, long-term tube feeding, and other medical conditions.

Biotin has also been used to treat seborrhea (skin rash) in babies. However, research has shown that Biotin may not be effective in treating this condition.

Other uses not proven with research have included treating brittle nails or thinning hair, diabetes, nerve pain, and other conditions.

It is not certain whether Biotin is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Biotin should not be used in place of medication prescribed for you by your doctor.

Biotin is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Biotin may also be used for purposes not listed in this product guide.

Biotin indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

The anticonvulsants carbamazepine, phenytoin, Phenobarbital, and primidone may accelerate Biotin metabolism, leading to a reduction in available Biotin. Chronic use of these drugs has been associated with decreased plasma concentrations of Biotin.

The use of antibiotics may reduce the contribution of Biotin made by bacteria within the large intestine.
