Biotin, or vitamin B7, is a type of water-soluble vitamin that is needed by our body to function properly. It is an important constituent of enzymes for the processing of macronutrients including fats and carbohydrates. You can ensure enough consumption of the nutrient in the form of biotin tablets. Another way to ensure enough intake is to include biotin-rich foods like oats, egg yolk, meat, fish, nuts and seeds, wheat germ, and certain vegetables to your diet.

Why Does Our Body Need Biotin?

Our body needs biotin for the formation of a protein called keratin. This protein plays a key role in the composition of our hair, skin, and nails. Biotin is also important to maintain healthy skin, digestive system and metabolic function.

A deficiency in this vitamin may cause brittle nails, hair loss, skin rashes, nausea, abdominal discomfort, and other issues.

Using Biotin to Boost Hair Growth and Prevent Hair Loss

The most common use of biotin is to maintain hair health. A lot of hair care companies also advertise the presence of biotin for their products as a useful property. Biotin for hair growth can be utilised to promote volume, enhance thickness, and increase scalp coverage. This is because of the keratin production stimulated by biotin that boosts the growth rate for hair follicles.

Biotin deficiency can be said to be the primary cause of hair loss or thinning of hair in different individuals. This is because it is an essential nutrient for hair health maintenance. A well-balanced diet with sufficient amounts of biotin may be helpful in the achievement of optimal levels, thereby preventing hair loss.

Scientific Studies on Biotin Deficiency and Hair Health

Multiple studies have been conducted on the effect of vitamin B7 on hair. In most of the studies, it can easily be concluded that the nutrient can be utilised to prevent hair loss. However, there isn’t sufficient evidence to suggest any solid effects for growth of hair.

Scientists claim that biotin intake in any form is highly beneficial for those suffering from a vitamin B7 deficiency. This deficiency can either be because of known causes or due to any underlying conditions. But when it comes to the effects of the intake of this nutrient in deficient individuals, it can prove to be greatly advantageous.

Due to this reason, consumption of biotin in the form of dietary aid is highly beneficial to amplify hair health for those suffering from alopecia or biotin deficiency in general.

Optimal Biotin Intake for Healthy Hair and Other Benefits

As much as this nutrient is helpful for hair, skin, nails, and multiple bodily functions, intake in moderate amounts is important. The recommended daily intake is 30 micrograms (mcg) for healthy adults. However, consultation with a physician is suggested for the required intake based on your existing and underlying health conditions.

Precautions to Practise While Consuming Vitamin B7

Applying biotin products on skin may cause irritation or rashes for those with sensitive skin. Therefore a patch test before consuming may help determine suitability to avoid any long-term effects.

When consuming biotin by mouth, it is important to practise moderation, so as to not exceed the recommended amounts. Exceeding this amount may hinder blood tests for various diseases like thyroid.


It can easily be concluded that biotin intake is highly beneficial for those suffering from a deficiency of the nutrient. It helps hair regrowth and maintain healthy, lustrous locks.
