Can you please tell me about some great vitamins for grandparents to eat?

TypicallyNone,Unless: Vitamins big business marketing without scientfic evidence of real value, exempted from proof in us: dshea act 1994. Best eat real food, avoid most all the processed junk in grocery middle isles. A few vitamin deficiencies are more common, e.g. Vit. D3. Thus check & target treat to specific goal if an issue. One size does not fit all, indeed usually fits no one well.
