Biotin for skin, hair, and nails? Does it help?

Also known as vitamin B7, biotin is a water-soluble vitamin and a part of the B complex vitamins. It acts as a coenzyme to help convert nutrients such as amino acids, fatty acids, and glucose into energy. These are nutrients released when protein, fats, and carbohydrates, respectively, get digested in the body. Without biotin, it’s difficult for the body to metabolite such nutrients.

Biotin also plays a vital role in maintaining healthy hair, skin, and nails.

Biotin is sometimes referred to as vitamin H, which comes from the German word Haut or Haar, which means hair and skin.

The fact that it’s water-soluble means it’s not stored in the body. So you have to consume it regularly to meet your daily requirements.

Biotin deficiency is very rare, making it difficult to ascertain how much biotin is too low or too high. But generally, the recommended daily value is 30 mcg per day. Nonetheless, deficiencies may result in hair loss or thinning and a scaly red rash on the skin.

Vitamin B7 is a common ingredient in most hair and skin products. But even so, most studies suggest that biotin is poorly absorbed when applied topically, and you can experience its uttermost benefits when ingested from either food or supplements.
