Biotin, also known as vitamin B7 or vitamin H, has become a popular biotin supplement in the health and beauty industry especially for those looking to improve hair, skin, and nail health. But what exactly is biotin, and what does it do for your body?

In this 2025 updated guide, we’ll break down everything you need to know about biotin its uses, dosage, benefits, side effects, and more. 

What is Biotin?

Biotin is a water-soluble B-vitamin that plays a crucial role in metabolizing fats, carbohydrates, and proteins. It supports the health of your hair, skin, nails, nervous system, and more. Since the body doesn't store biotin, it’s important to get it from food or supplements regularly.

Top Biotin Benefits (2025 Updated)

These are the benefits of Biotin:

Promotes Healthy Hair Growth

One of the most well-known benefits of biotin is its ability to support hair health. It helps strengthen hair strands, reduce breakage, and improve shine. In 2025, biotin supplements continue to be widely used in hair care routines.

Improves Skin and Nail Health

Biotin can enhance the strength and texture of nails and may help reduce skin issues like dryness or rashes. People with brittle nails often notice improvement within weeks of taking a biotin supplement.

Boosts Metabolism

Biotin plays an essential role in converting food into energy. It helps enzymes break down carbohydrates, fats, and proteins, making it important for a healthy metabolism.

Supports Brain Function

Vitamin B7 supports cognitive health and the nervous system. A deficiency in biotin can lead to fatigue, mood swings, and difficulty concentrating.

May Help in Pregnancy

Biotin requirements increase during pregnancy. Many doctors recommend prenatal supplements that include biotin to support fetal development and maternal health.

Common Food Sources of Biotin

You can find natural biotin in foods such as:

• Eggs (especially the yolk)
