What helps absorb biotin?

To maximize the intake of biotin and for safety reasons, always cook eggs before eating them. Raw egg white contains a protein called dietary avidin, which binds to biotin and makes it harder for the body to absorb it. Cooking separates the biotin from the avidin, helping the digestive tract to absorb the vitamin.

In this article, find out more about foods that provide biotin and ideas for incorporating them into the diet. Biotin is present in many foods, including egg yolk, liver, avocado, and some vegetables. It is also available as a supplement. Biotin is water-soluble , which means that the body cannot store it — a person needs to get it from their diet. The gut can create some biotin, but experts do not know how much of this the body can absorb. Many people take biotin to improve the condition of their hair and nails, but little evidence supports this use, in most cases. A lack of biotin can lead to problems with the nervous system, skin, hair, and nails, according to the Office of Dietary Supplements (ODS). It may also support the immune system. Biotin is a water-soluble vitamin and an essential nutrient. Also called vitamin B-7, biotin helps convert food into fuel for the body. Eating a varied diet can usually provide enough biotin for most people’s needs.

Below are some good dietary sources of biotin.

Liver and other meats

Including liver in the diet can boost a person’s biotin intake.

A 3-ounce serving of cooked beef liver contains about 31 micrograms (mcg) of biotin.

Other organ meats, such as kidney, are also good sources.

Different types of meat contain less biotin, but they are still relatively good sources. For example, a 3-ounce pork chop provides nearly 4 mcg, as does a cooked hamburger patty. A 3-ounce serving of meat is approximately the size of a deck of cards. Liver is also a good source of iron. Here, find out why we need iron.

Egg yolk

Egg yolk is a good source of biotin. A whole, cooked egg provides up to 10 mcg . To maximize the intake of biotin and for safety reasons, always cook eggs before eating them. Raw egg white contains a protein called dietary avidin, which binds to biotin and makes it harder for the body to absorb it. Cooking separates the biotin from the avidin, helping the digestive tract to absorb the vitamin.
