Biotin, also known as vitamin B7, is a water-soluble vitamin that is essential for many bodily functions. It is involved in the metabolism of fats, carbohydrates, and proteins, and it also plays a role in the production of energy and cell growth. Biotin is found in many foods, including eggs, liver, nuts, seeds, and whole grains.
Biotin deficiency is rare, but it can occur in people with certain medical conditions, such as malnutrition, kidney disease, and liver disease. Deficiency can lead to a variety of symptoms, including hair loss, skin problems, and fatigue.
Biotin supplements are often taken by people who want to improve their hair, skin, and nail health. However, there is limited scientific evidence to support these claims. Some studies have shown that biotin supplements may help to improve hair thickness and nail strength, but more research is needed.
Overall, biotin is an important nutrient that plays a role in many bodily functions. However, most people get enough biotin from their diet, and there is limited evidence to support the use of biotin supplements for hair, skin, and nail health.
How Does Biotin Work?
Biotin works by helping enzymes in the body break down carbohydrates, fats, and proteins. This process releases energy that the body can use for cell growth and repair. Biotin is also involved in the production of fatty acids, which are important for cell membranes and other bodily functions.
In addition to its role in energy metabolism and keratin production, biotin is also involved in other important bodily functions, including:
- Metabolism of amino acids: Biotin helps the body break down amino acids into their building blocks, which can then be used to build new proteins.
- Production of red blood cells: Biotin is involved in the production of heme, a component of hemoglobin, which carries oxygen in the blood.
- Function of the nervous system: Biotin helps to maintain the health of nerve cells and myelin, the fatty substance that insulates nerve fibers.

Benefits of biotin for skin health:
- Improves skin barrier function: Biotin helps to strengthen the skin barrier, which protects the skin from moisture loss and environmental irritants.
- Reduces inflammation: Biotin has anti-inflammatory properties, which can help to reduce skin inflammation and redness.
- Promotes wound healing: Biotin helps to promote wound healing by increasing the production of collagen and elastin, two proteins that are essential for skin repair.
- Reduces acne: Biotin may help to reduce acne breakouts by regulating sebum production and reducing inflammation.
- Improves skin elasticity: Biotin helps to improve skin elasticity by increasing the production of collagen and elastin.
- Reduces wrinkles and fine lines: Biotin may help to reduce wrinkles and fine lines by improving skin elasticity and hydration.
What Are the Benefits of Biotin for Nail Strength?
It is involved in the production of keratin, the main protein that makes up nails. Biotin also helps to regulate nail cell turnover and promote nail growth.
Benefits of biotin for nail strength:
- Strengthens nails: Biotin helps to strengthen nails and make them less prone to breakage and splitting.
- Improves nail flexibility: Biotin helps to improve nail flexibility and make them less brittle.
- Increases nail thickness: Biotin helps to increase nail thickness and make them more durable.
- Reduces nail ridges: Biotin may help to reduce nail ridges and uneven surfaces.
- Improves nail color and luster: Biotin may help to improve nail color and luster by promoting healthy nail growth.
What Are the Benefits of Biotin for Other Health Benefits?
In addition to its benefits for hair, skin, and nails, biotin may also have other health benefits, such as:
- Regulating blood sugar levels: Biotin may help to regulate blood sugar levels by improving insulin sensitivity. This could be beneficial for people with type 2 diabetes.
- Reducing cholesterol levels: Biotin may help to reduce cholesterol levels by increasing the excretion of bile acids. Bile acids are produced in the liver and help to digest fats.
- Improving cognitive function: Biotin may help to improve cognitive function by increasing the production of myelin, a fatty substance that insulates nerve fibers. This could be beneficial for people with multiple sclerosis and other neurological disorders.
- Supporting pregnancy: Biotin is essential for the healthy development of the fetus during pregnancy. Pregnant women should consume at least 30 micrograms of biotin per day.
What Are the Sources of Biotin?
Food sources of biotin
