Vitamin B7, H (Biotin)
Use
Vitamin B7, also known as biotin, is a crucial micronutrient involved in energy metabolism and synthesis of important biomolecules. Biotin is essential for maintaining healthy skin, hair, and nervous system function. Monitoring biotin levels assists in diagnosing biotin deficiency, which can manifest as skin rashes, hair loss, and neurological symptoms. Adequate biotin levels are significant for individuals relying on parenteral nutrition or exhibiting symptoms consistent with biotin deficiency.
