Biotin is a water-soluble vitamin that’s a part of the vitamin B family. It’s also known as vitamin H. Your body needs biotin to help convert certain nutrients into energy. It also plays an important role in the health of your hair, skin, and nails.
If you aren’t getting enough biotin, you may experience hair loss or a scaly red rash.
Keratin is a basic protein that makes up your hair, skin, and nails. It’s clear that biotin improves your body’s keratin infrastructure.
If you don’t think you’re getting enough biotin from your diet, or if you’re just looking to up your dosage, supplements may be an option.
Biotin supplements are available over the counter in capsule or tablet form.
