Biotin, or vitamin B7, is vital for turning food into energy and supports healthy skin, hair, and nails. It's key in metabolizing fats, carbohydrates, and proteins. Biotin deficiency is rare, but supplements are often used to enhance hair and nail health....


Who would benefit from testing their biotin levels?

  • Individuals experiencing symptoms of biotin deficiency, like hair loss, skin rashes, or brittle nails.
  • Those with conditions affecting nutrient absorption, such as Crohn’s disease or other gastrointestinal disorders.
  • People on long-term anticonvulsant therapy, as some medications can reduce biotin levels.
  • Pregnant women, as pregnancy can sometimes lead to lower biotin levels.
  • Individuals following a diet that may lack sufficient biotin, like raw egg diets (raw egg whites contain a protein that binds biotin and prevents its absorption).
  • Those with genetic conditions affecting biotin metabolism.

What symptoms does biotin deficiency cause?

  • Hair loss
  • Red, scaly rash around eyes, nose, and mouth

What foods are high in biotin?

Foods high in biotin include egg yolks, nuts and seeds such as almonds, sunflower seeds, and peanuts, as well as liver and other organ meats. Whole grains and cereals, avocados, cauliflower, mushrooms, dairy products like milk and cheese, and salmon and other fatty fish are also good sources of biotin. These foods can help maintain adequate biotin levels in the body.

What are the benefits of biotin supplementation?

Biotin supplements can help improve hair health, strengthen nails, and enhance skin quality, especially in those with biotin deficiency.
