What is Vitamin B7?

However, since biotin deficiency is rare and the amounts needed by the body are small, many countries do not actually provide a recommended daily intake of biotin.

Because it’s a water-soluble vitamin, any excess is excreted through urine. For profound deficiency, treatment is oral dosing with 5 to 20 mg per day. It is also important in freeing biotin from dietary protein-bound biotin. Urinary excretion of this compound is an early and sensitive indicator of biotin deficiency. Subclinical deficiency can cause mild symptoms, such as hair thinning, brittle fingernails, or skin rash, typically on the face. SMVT also binds pantothenic acid, so high intakes of either of these vitamins can interfere with the transport of the other. The large intestine microbiota synthesizes amounts of biotin estimated to be similar to the amount taken in the diet, and a significant portion of this biotin exists in the free (protein-unbound) form and, thus, is available for absorption. The vitamin’s influence on the skin may stem from its effect on fat metabolism. Some people also believe that biotin may help improve psoriasis. This level of deficiency may affect a person’s health, but not enough to cause noticeable symptoms. Changing the diet and other lifestyle factors can help improve nail health, as can some commercial products.

Good sources of vitamin B12

Biotin is often added to multivitamins and hair/nail/skin supplements. An RDA (Recommended Dietary Allowance) does not exist for biotin because there is not enough evidence to suggest a daily amount needed by most healthy people. It is a water-soluble B vitamin found naturally in some foods and also in supplements. Results after 4–6 months from supplementing biotin at 20 mg/day into daily diet reduces the risk of lameness. A review of the fingernails literature reported brittle nail improvement as evidence from two pre-1990 clinical trials that had administered an oral dietary supplement of 2.5 mg/day for several months, without a placebo control comparison group. That’s why it’s important to discuss biotin supplementation with your doctor, especially if you have to undergo any clinical tests. For adults, the RDI is about 30 micrograms (mcg) of vitamin B7 per day. Supplements may be useful for individuals who struggle to meet their vitamin B7 requirement through diet alone.

The discussion speculated that this could be an indirect consequence of improved hoof health or a direct effect on milk production. The proposed mechanisms are that biotin activates acetyl-CoA carboxylase, a key rate-limiting enzyme during the synthesis of myelin, and by reducing axonal hypoxia through enhanced energy production. The hypothesis is that biotin may promote remyelination of the myelin sheath of nerve cells, slowing or even reversing neurodegeneration. The initial step was described as a condensation of pimelyl-CoA and alanine to form 7-oxo-8-aminopelargonic acid. Gyorgy continued his work on biotin and in 1941 published a paper demonstrating that egg-white injury was caused by the binding of biotin by avidin. The name biotin derives from the Greek word bios ('to live') and the suffix "-in" (a general chemical suffix used in organic chemistry). If you're taking folic acid supplements, it's important not to take too much as this could be harmful. If you take biotin supplements, do not take too much as this might be harmful. If you take vitamin B6 supplements, do not take too much as this could be harmful.

Biotin supplements are often glamorized as a treatment for hair loss and to promote healthy hair, skin, and nails. When people are ingesting high levels of biotin in dietary supplements, a consequence can be clinically significant interference with diagnostic blood tests that use biotin-streptavidin technology. Aside from inadequate dietary intake (rare), biotin deficiency can be caused by a genetic disorder that affects biotin metabolism. Primary biotin deficiency, meaning deficiency due to too little biotin in the diet, is rare because biotin is contained in many foods. Biotin is commonly advised as a dietary supplement for strengthening hair and nails, as well as in skin care. Although biotin deficiency is rare, some groups of people may be more susceptible to it, such as patients suffering from Crohn’s disease. In general, a healthy varied diet provides the body with sufficient amounts of biotin. Biotin exists in a wide variety of foods, which helps explain why a deficiency in the vitamin is fairly rare.
