A water soluble vitamin, vitamin B7 is an essential B-complex vitamin. It is also known as Biotin or vitamin H and is a significant part of a healthy metabolism and production of essential enzymes in the human body. It is helpful in strengthening hair, nails and skin. Biotin is needed for the production of many fatty acids and glucose which are the energy reserves of our body. It cannot be produced by the human body, but the good bacteria in the gut synthesize it which gets used up by our body. Our body primarily needs biotin or vitamin B7 for metalizing fats, carbohydrates and proteins. It also acts as a coenzyme for carboxylase enzymes, which are involved in gluconeogenesis, synthesis of fatty acids as well as some amino acids. It has rejuvenation properties that help in producing new cells in the body, which helps in preventing hair loss and hair shedding. It promotes hair regeneration and development of follicles and scalp. Vitamin B7 is also known to support collagen synthesis, which provides elasticity and flexibility to the nails and prevents damage. 

Some natural sources of biotin include egg yolks, whole grains and cereals, cauliflower, mushrooms, bananas, soybean, nuts, meat and dairy products. It is advised to have these foods in the raw form as food processing techniques can make biotin ineffective. Taking vitamin B7 is considered better when taken from natural sources. Fruits and vegetables also contain biotin.

Large doses of vitamin B7 is known to have no toxic effects on our body, but it may interact with some drugs, herbs or supplements. For example, if it is taken with alpha linoleic acid, absorption of both alpha linoleic acid and biotin might get affected or might not happen at all. The same scenario is seen in vitamin B5 and pantothenic acid. Supplementation of biotin may also interact with medicines that are metabolized by the liver, such as clozapine or clozaril, haloperidol, olanzapine etc.

Benefits of Biotin or vitamin B7

  • Promotes a healthy pregnancy: biotin deficiency is often observed in pregnant women, which, if left untreated, can also lead to abnormal development of the fetus. Many doctors around the globe recommend supplementation of Folic acid during pregnancy. Multivitamins with a minimum of mcg of biotin as well as folic acid are a good choice to avoid risks and chances of deficiency. 
  • Lowers blood glucose levels: biotin shows great effects in the stimulation of the secretion of insulin from the pancreas and lowering the blood glucose, animal studies suggest. Promising results have been demonstrated by biotin in various research studies, for both type-I and type-II diabetes. Biotin may also assist in glycemic control in people who have type-I diabetes. 
  • Helps in reducing chances of nerve damage: chances and risks of nerve damage can be significantly reduced by Biotin, in people who are diabetic or are undergoing dialysis for kidney disorders. Research that was carried out with some patients, found out that long term usage (1 to 2 years) of Biotin can actually improve symptoms of nerve damage. It is a necessary vitamin which maintains the levels of pyruvate carboxylase. With biotin deficiency, high levels of pyruvate and aspartate may rise, which can affect the nerves. However, more research is needed to draw more firm conclusions.
  • Helps in treating stiff tissues of the central nervous system: high dose biotin therapy can actually improve the symptoms of diseases that particularly affect the central nervous system. Multiple sclerosis is one of those. It is an autoimmune disease that affects the nervous system, leading to weakness and other health issues. In a research study, it was found out that even large doses of biotin reduced symptoms of this disease in the participants. 
  • Helps in treating basal ganglia disease: basal ganglia disease (biotin-responsive) is a very rare inherited disorder. It affects the nervous system, specifically the part that controls all the functions. This, in turn, can lead to involuntary tensing of muscles. 
  • Strengthens hair, skin and nails: people with biotin deficiency often experience hair loss or scaly and reddish rashes. Some limited research studies have found out that biotin or vitamin B7 can enhance the strength and durability of nails, hair and skin. Brittle nail syndrome is an abnormality with heterogeneous effects that makes the nail plates fragile and weak. This syndrome may be treated by biotin supplementation, studies suggest. In one study, which was carried out with 45 patients, it was found out that 91 percent of these people had stronger and firmer nails after taking 2.5 mg of vitamin B7 every day. In another research study, biotin demonstrated some great effects against hair thinning in some women. However, some more research for vitamin B7 and its benefits is needed.  

Deficiency of biotin

Although rare, biotin deficiency can cause some mild to serious symptoms that can affect our lives. It is a very rare deficiency, because, an average human diet consists of biotin and the gut bacteria can synthesize it.

Some symptoms or signs of biotin deficiency are:

  • Hair loss, hair thinning or alopecia.
  • Depression or anxiety.
  • Fatigue
  • Ataxia- loss of control of body movements
  • Seizures or hallucinations
  • Impaired immune functions in the body
  • Increased risk of infections.
  • Dry eyes
  • Nausea
  • Swollen, dark tongue
  • Muscular pain
  • Loss of appetite and insomnia
  • Cracking on the lips

Biotin deficiency may also adversely affect people with liver diseases, or those who use epilepsy medications. People who are most likely to get biotin deficient are: pregnant women, people who received prolonged intravenous glucose, infants consuming breast milk which is low in biotin, people with inflammatory bowel disease.
