Biotin is required for the proper functioning of the body’s metabolism. It functions as a coenzyme in a variety of metabolic processes including fatty acids and essential amino acids, as well as gluconeogenesis (the production of glucose from non-carbohydrate sources). Although biotin deficiency is uncommon, some people are more vulnerable than others, such as Crohn’s disease sufferers. Hair loss, skin disorders such as dermatitis, cracking in the corners of the mouth, dryness of the eyes, and appetite loss are all indications of biotin deficiency. Vitamin B7 helps the neurological system operate properly and is also necessary for liver metabolism.
Biotin is often recommended as a dietary supplement for hair and nail strength, as well as for skin maintenance. Biotin is thought to help with cell proliferation and mucous membrane maintenance. Although biotin is found in some cosmetics, it is vital to keep in mind that it cannot be absorbed through the skin, hair, or nails.
Vitamin B7 can help with thinning hair and brittle nails, especially in people who are deficient in biotin. However, there has been no conclusive evidence to support the idea that biotin is directly linked to improved skin and nail health or enhanced hair development.
