Biotin, classified as vitamin B7 or vitamin H, is a water-soluble nutrient vital for numerous metabolic functions in the body. It serves as a cofactor for several enzymes involved in crucial processes like fatty acid synthesis, gluconeogenesis, and amino acid metabolism.
Biotin also plays a pivotal role in maintaining healthy skin, hair, and nails. Furthermore, it supports proper nervous system function by aiding in neurotransmitter synthesis.
While biotin deficiencies are rare, they can lead to symptoms like hair loss, skin rashes, and neurological issues. Dietary sources of biotin include eggs, nuts, seeds, meats, fish, and certain vegetables.
