What Is Biotin?
Biotin is a water-soluble B-Vitamin also known as coenzyme R, Vitamin B7, or Vitamin H.
Vitamin B7 is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring.
This B-Vitamin naturally occurs in many of the common foods that we use in our daily diet.

Biotin For Hair Growth
Does biotin work for hair growth? This is a widely debated and discussed topic among most dermatologists and hair experts.
At the outset itself, it must be noted that there is insufficient scientific backing to prove the effectiveness of biotin for hair growth.
However, this vitamin is such an important vitamin in helping several body functions and overall growth, there is a strong link between biotin and hair.
Let us see how biotin helps in hair growth and in preventing hair loss:
- Biotin deficiency leads to hair breakage and hair loss along with cracked and brittle nails
- Biotin supplements have proven an effect on increased hair growth, reduction in hair fall, and removal of hair dryness.
- Sulfur is one of the active components of biotin that is good for the production of collagen that will help in the growth of strong hairs
- Biotin is one of the essential nutrients required for the growth and regenerations of hair follicles from which the hairs develop
- Biotin together with Vitamin E helps the hair lot in maintaining natural hair moisture and also helps in adding shine to the hair
It is important to understand that hair growth depends on combinations of vitamins and minerals. Biotin or Vitamin B7 is one of the vitamins required by the hair for its growth and strength.
Biotin deficiency is one of the reasons for thinning and breakage of hair. It essentially means that all hair loss instances and stunted hair growth are not always due to a lack of biotin.
Intake of Vitamins B7 rich foods or supplements is a good way to help your hair to grow better.
People who take alcohol indeed tend to lose more hair than others because alcohol directly interferes with the effects of biotin.
The raw egg whites contain a glycoprotein called avidin that is effective in binding biotin, one of the B vitamins. This suppression of Vitamin B7 by the raw egg whites will actually lead to a deficiency of this vitamin in the body. That’s the reason many people say that eating raw eggs will cause hair to fall.
If you are suffering from excessive hair fall or breakage, it is good to do a clinical test to find the biotin levels in your body. If test results indicate low levels of biotin in your body, then you can assume that biotin deficiency is one of the reasons that have made your hair weaker and highly prone to breakage.
It is only the continuous growth of hair that will make your hair long. It is good to eat natural foods that contain biotin and other vitamins such as Vitamin A, E, D, and minerals like iron, zinc, and potassium to make your hair grow healthy and long.
Here is a video in which Dr.Oz speaks on how biotin helps in hair growth:

Biotin is a naturally included vitamin in most common foods that we consume. If you already have a healthy and balanced daily diet, there is hardly any need to go for an additional boost unless your doctor recommends it.
Biotin is LIKELY SAFE to consume as most people won’t be affected by any adverse health effects from it.

In every healthy person, the body has the natural capacity to tolerate biotin supplements. It is also found that the injections containing Vitamins B7 are also SAFE for health provided the dosage does not exceed the clinically permissible amount.
However, there are some cases of Biotin side effects noticed in some areas or diseases related to health. Let us see some of the cases where biotin side effects could exist:-

Allergic reactions are possible in persons who are normally sensitive to supplements and medicines. It is found people who have allergies to B12 vitamins are quite possible to face the same with biotin pills too. In the case of allergic reactions like nausea, itchy rashes, pain in the stomach or chest, etc., should immediately consult a competent doctor.
Increased chance of miscarriage is a side effect of biotin when it is taken in a higher dose than the permissible amount. It also risks the health of the fetus… never take any supplements or medicines during pregnancy without the recommendation of the physician.
The interactive issue with other medicines is one of the known biotin side effects. The vitamin B7 supplement can adversely interact with medications used for epilepsy, cholesterol, etc. making those medicines work less effectively.
Blood glucose levels may affect adversely the intake of biotin. Normally Vitamin B7 is useful for improving the blood sugar to a balanced level, but taking biotin supplements and diabetes medicines at the same time can bring down the sugar levels lower than the optimum level.
Biotin side effects can occur in a person under heavy medication as their system may not respond positively to the additional biotin intake. It may also interact with other medicines that may give rise to unexpected physical discomforts.
