Biotin is an essential vitamin that helps your body utilize nutrients for energy.


Healthy levels of Biotin can help thicken hair and support nail and hair growth.

Biotin is a B vitamin needed to help promote healthy hair, skin, and nails.

Maintaining healthy levels of Biotin in the body can help combat hair loss, brittle nails, and some skin issues.

Biotin hair support


Biotin works by stimulating the production of keratin. Keratin is a type of tough protein which is a building block of many parts of the body, including your hair. Did you know that about 95% of your hair is made up of this protein? Boosting your keratin levels can increase the rate of follicle growth, leading to healthier hair.

Biotin nail health


Keratin also affects nails. It can influence the appearance, texture, shape, strength, and resilience of your nails. If you are experiencing brittle, splitting, or soft nails, these signs could be pointing to a deficiency in keratin.

Biotin nail health


The cells in the epidermis are made up of keratin. A biotin deficiency can affect the amount of keratin in your skin and lead to red, dry, or scaly rashes. This effect is linked to the fat metabolism process.

Biotin metabolism


Biotin is one of the B-complex vitamins that support several enzymes for converting food into energy. The vitamin is involved in the following processes:

  • Gluconeo­genesis
  • Breakdown of amino acids
  • Synthesis of fatty acids
