In addition to the commonly known vitamins such as A, B, C, D and E, there is also a vitamin H, also known as biotin. Like vitamins B and C, biotin (sometimes referred to as vitamin B7) is water-soluble. This means that any excess vitamin will be excreted by the body, and won’t build up to harmful levels. Vitamin H is also produced within the body’ intestinal tract, however, additional amounts from external sources such as supplements can have many benefits.
Biotin is necessary for the development of healthy tissues, such as skin, muscle, hair and bones. It assists in the metabolization of fatty acids into energy, and assists in breaking down glucose. Some studies have shown that biotin may be able to lower glucose levels in blood.
Biotin is best known for supporting the health of the skin, hair and nails. In fact, the name vitamin H originally came from the German terms “haar” and “haut,” which translates to hair and skin. Biotin is generally recommended as an over-the-counter solution for dry or thin hair, brittle, thin nails, and dry, dull skin. Many topical products such as lotions and shampoos contain biotin. However, it is not absorbed well from external sources. It is much more effective to ingest a biotin supplement.
The National Institute of Health recommends that adults receive 30 micrograms of biotin per day. Because it is water soluble, taking supplements is very safe and it is difficult to overdose. However, it can interfere with certain prescriptions, so always check with a doctor if you take other medications.
