What is biotin? Biotin is a water-soluble vitamin classified as a B- complex vitamin. It is required by all organisms but can be synthesized by only bacteria, yeasts, molds, algae, and some plant species. Biotin, just like all B vitamins helps convert food (carbohydrates) into energy (glucose). It also helps the body to breakdown fats and proteins. B complex vitamins are required for healthy eyes, skin and hair. But is it really considered a vitamin?
Is biotin a vitamin? What kind of vitamin? Biotin is a B complex vitamin that has been previously known as Coenzyme R, vitamin H or vitamin B7. These names came about due to the uncertainty surrounding its role in normal metabolism.

Biotin Uses-Use of Biotin for Hair Growth and Hair Loss
There are various uses of biotin for hair loss, hair thinning and even to grow facial hair. It is very important to understand that biotin does not stimulate new hair growth. Rather it renews follicles and root hairs that are already growing.

Biotin deficiency can lead to hair thinning and eventually hair loss.

However, there is not enough evidence to support biotin’s effectiveness in managing hair thinning and hair loss.
Use of Biotin for Nails Growth, Brittle & Skin

It is however suggested that it works on nails the same way it does on hair by renewing cells, which are the building blocks of the body including nails.
Biotin for nail growth uses: Nails have a fibrous protein called keratin. Biotin is easily absorbed to the core of the nail where it thickens and encourages nail growth. The recommended dose of biotin for nails that are thicker and healthy is 30mcg daily for at least one month.
Biotin for brittle nails uses: If you have brittle nails that break easily, nutrients like biotin can help strengthen them and reduce tendency to split. People who have used biotin for nails report to have seen positive results after about one month of daily intake of biotin supplements.
Uses of Biotin for Skin
What does biotin do for your skin? Biotin is very essential in metabolism of fatty acids. Proper breakdown of fats is critical for a healthy skin. Due to constant contact with external environment, skin cells are rapidly replaced. Fatty acids in the skin protect the cells against water loss and damage. When biotin intake is not adequate, fat metabolism is altered making the skin cells the first to develop symptoms.
So, does biotin work to nourish the skin? It works by renewing body cells and aiding in breakdown and proper distribution of body fats. For details on biotin for skin check out this post: Biotin for Skin – What Does Biotin Do for Skin, Biotin Skin Benefits, Reviews & Results
