Multivitamin tablets are dietary supplements containing a blend of essential vitamins and minerals, typically without a single molecular formula or CAS number due to their composite nature. Common ingredients include vitamin C (ascorbic acid, CAS 50-81-7), vitamin D3 (CAS 67-97-0), and B-complex vitamins (e.g., B12, CAS 68-19-9), combined with minerals like zinc (CAS 7440-66-6) and iron.
