Biotin Supplements Guide

Biotin is necessary for the metabolism of amino acids and fat, production of fatty acids, and cell growth. A wide range of foods contains biotin. Few foods have a particularly high biotin content. Saskatoon berries, liver, raw egg yolk, green leafy vegetables and peanuts have a relatively high content of biotin.

Athletes, elderly individuals, epileptics, burn patients, and patients that underwent a partial gastrectomy tend to have low biotin levels. Lactation and pregnancy have an association with an increased biotin demand. Typical biotin deficiency occurs from an absence in the diet.

Symptoms include neurological symptoms such as extremity tingling and numbness, lethargy, and depression in adults; dermatitis; conjunctivitis; hair loss; and thin and brittle fingernails. A nutritional supplement can address a biotin deficiency.

What is a Biotin Supplement?

The Mayo Clinic has this to say about biotin supplements. Biotin supplements are aids in the prevention or treatment of a biotin deficiency. Biotin is a form of Vitamin B. Vitamins are compounds needed for growth and health. Only small amounts are necessary and are available in food.

Biotin is a necessity for the formation of glucose and fatty acids, which the body uses as fuel. Biotin is important for metabolizing carbohydrates and amino acids. Lack of biotin is rare. Therefore, there is no recommended dietary allowance. The needed biotin comes from adequate nutrition in most healthy individuals.

If a person or health care professional feels the amount of biotin is inadequate, a biotin supplement is a choice or suggestion. The supplement works in combination with food.

Things to Look for in a Good Biotin Supplement

The U.S. Food and Drug Administration, health professionals, and the organizations they belong to, receive inquiries from consumers seeking health-related information about dietary supplements. In an article published on the internet, the FDA acknowledges people who choose to supplement their diets with minerals, vitamins, herbals, and other substances want information about the products they choose. The article suggests being able to answer these questions.

  • Does my diet provide an adequate supply of biotin?
  • Have I discussed adding a biotin supplement with my healthcare provider?
  • Will the supplement interact with OTC or prescription medications I am taking?

An acceptable biotin formula has only top quality biotin with at least 10,000 mcg per serving. Cheap fillers, binders, and synthetic ingredients are not in quality biotin products. The manufacturer of quality biotin supplements has a strong return policy that shows it stands behind its product.

Taking a Biotin Supplement

A Consumer Review study analyzed biotin and determined the amount needed to produce results is a minimum of 10,000 mcg daily. There are varieties of biotin that dissolve in the mouth for people who find swallowing a pile difficult. Biotin is also available in rapid release soft gel tablets. A gummy variety is preferred by some.

The package directions give the dosage to take on a daily basis. No adverse health effects are known, but a discussion with your doctor is recommended before taking any dietary supplement.
