Biotin, also known as vitamin B7, is a water-soluble vitamin that is essential for a healthy body. It plays a vital role in many important bodily functions, including the metabolism of carbohydrates, proteins, and fats.

While biotin deficiency is rare, it can lead to a variety of health problems, including skin rashes, hair loss, and neurological issues.

In this article, we will explore the benefits of B7 for skin and health.

Promotes Healthy Hair

B7 is often referred to as the "hair vitamin" due to its ability to promote healthy hair growth. It works by strengthening the hair follicles and promoting the growth of new hair cells. It can also help to reduce hair loss and improve hair thickness and hair shine.

Improves Skin Health

B7 plays a crucial role in promoting healthy skin by supporting cell growth and repair. It can help reduce inflammation and promote the production of new skin cells, which can improve skin texture and reduce the appearance of acne. It also helps to maintain the skin's moisture barrier, preventing dryness and flakiness.

Strengthens Nails

B7 is also essential for strong, healthy nails. It can help reduce nail brittleness and improve thickness and overall nail health. It works by promoting the production of keratin, a key protein that makes up nails.

Supports Metabolism

B7 is important for the metabolism of carbohydrates, proteins, and fats. It helps break down these macronutrients into energy that the body can use for various functions, including physical activity and cellular processes.

Reduces Inflammation

B7 has anti-inflammatory properties that can help reduce inflammation throughout the body. This can be beneficial for those with inflammatory conditions like arthritis or skin conditions like eczema.

Regulates Blood Sugar

B7 can help regulate blood sugar levels by improving the body's ability to use insulin. This can be beneficial for those with type 2 diabetes or those at risk of developing the condition.

Supports Cognitive Function

B7 is important for healthy brain function, including memory and cognitive performance. It can help improve brain function in older adults and may also be beneficial for those with neurological conditions like multiple sclerosis.

  • Eggs
  • Almonds

  • Spinach
  • Salmon
  • Sunflower seeds
  • Avocado

B7 supplements are also available and can be beneficial for those who do not consume enough biotin throughout the diet.


Biotin plays a crucial role in maintaining healthy hair, skin, and nails, and its benefits go beyond just cosmetic concerns. Ensuring adequate intake of B7-rich foods and supplements can improve overall health and well-being.

However, it is important to note that excessive intake of B7 supplements can have adverse effects, and consulting with a healthcare professional is recommended before starting any new supplement regimen.
