Across three large, non-overlapping randomized trials within the COSMOS study family (total n≈6,400 older adults), daily multivitamin-mineral supplementation produced a small but statistically significant and consistently replicated benefit on global cognition and episodic memory, equivalent to roughly 2–3 years less age-related decline; it has shown no benefit for mortality in separate, larger trials.

Your journey
Cognitive Decline comes first (month 6 → 1 year); Cognitive Decline takes longest (month 6 → 1 year). An estimate from the studies' timelines, not a promise: everyone responds differently.
From the first noticeable effect to roughly full strength. Colour follows the XP tier of each benefit.
These gains come from steady use, not a single dose. Keep Multivitamin in your routine for about 1 year before you judge it.
