A credible daily multivitamin in 2026 prefers methylated B-vitamin forms (methylfolate over folic acid, methyl-B12 over cyanocobalamin) since a meaningful fraction of the population carries MTHFR variants that don’t efficiently process the unmethylated forms. Look for vitamin D3 (2000–5000 IU depending on baseline status — test first if you don’t know yours), vitamin K2 MK-7 (90–180 mcg) paired with D3 for calcium routing, magnesium glycinate or threonate (200–400 mg) rather than oxide, zinc (15–25 mg, balanced with copper at 1–2 mg to prevent imbalance), and a modest dose of selenium (100–200 mcg). For immune-specific stacks, vitamin C (500–1000 mg in divided doses), zinc, vitamin D3, quercetin (500 mg), elderberry extract (500–1000 mg standardized), and N-acetylcysteine (600 mg) form a defensible daily layer. Avoid the mega-dose multivitamins that contain 5000% of B-vitamin daily values — your body excretes the excess and the high doses can mask deficiency signals you’d otherwise notice. The form factor matters: capsules or tablets generally deliver more accurate dosing than gummies (which carry sugar and lower per-serving doses).
