Get To Know Your Vitamins – Vitamin B7 (Biotin) 2017-01-23T20:59:37-08:00

Vitamin B7 (Biotin)

Vitamin B7, it’s chemical name is biotin. As a member of the B complex family of vitamins, it is water soluble, so the body excretes what it doesn’t use and must replace it every day. Its essential role is to act as a coenzyme during the metabolism of proteins, fats and carbohydrates. Good dietary sources include oatmeal, eggs, peanuts and liver.

However bacteria in the intestine produce significant amounts of vitamin B7 which is also probably available for absorption and use by the body.

How it helps

Biotin, like the other B vitamins, is a necessary part of the process that turns food into energy. It also helps the body produce fatty acids, which is important because the body needs fat to replace dead cells. This is particularly critical for the skin, because the dead cells must be replaced quickly to keep the skin healthy so it can protect the body from the outside environment. In fact it can be helpful for cradle cap and brittle nails.

What happens if I don’t get enough?

Biotin is found in almost all foods, and bacteria in the intestine also create this vitamin, so deficiencies are rare. Deficiencies may occur in people who take a lot of antibiotics that kill the intestinal bacteria. When a deficiency does occur, the symptoms may include:
■ skin rash
■ muscle cramps and pain
■ fatigue
■ nausea
■ depression
■ loss of appetite
■ hair loss
