Notes:
The Food Safety and Standards Authority of India clarified the use of methylcobalamin (MeCbl), an active form of Vitamin B12. Methylcobalamin, structurally distinct from other Vitamin B12 forms, contains a methyl group bonded to a cobalt atom. It is found in supplements and food sources like fish, meat, eggs, milk, and milk products. Vitamin B12 is essential for DNA synthesis, red blood cell production, and neurological function. Deficiency can cause severe health issues, often requiring supplementation. It supports vital functions like cell growth, blood formation, and protein synthesis.
