    Vitamins for Seniors

    What you really need. What to skip.

    Most important

    • Vitamin D — bones + immune.
    • Vitamin B12 — energy + nerves.
    • Calcium — bones (with D).
    • Vitamin B6 — brain + energy.
    • Folate (B9) — heart + brain.
    • Doctor blood test confirms levels.

    Vitamin D specifically

    • 1,000-2,000 IU daily for most.
    • Reduces falls 20%.
    • Better immunity.
    • Sun = best source.
    • 15 min/day sun = baseline.
    • Pill if can't get sun.

    B12 — sneaky deficiency

    • 30%+ of seniors deficient.
    • Causes fatigue, depression, dementia symptoms.
    • Stomach acid decreases with age = absorption.
    • Sublingual or shot if very low.
    • Methylcobalamin form best.
    • Annual blood test critical.

    Multivitamin debate

    • Centrum Silver / One A Day 65+.
    • Senior-targeted formulas.
    • Some studies show benefit.
    • $15-30/mo.
    • Doctor often recommends.
    • Costco Kirkland half price.

    SKIP these

    • Vitamin E — high-dose risky.
    • Vitamin A — too much harmful.
    • Iron — unless deficient.
    • "Memory boosters" — unproven.
    • Beta-carotene — high dose risk.
    • Mega-doses — most harmful.

    Drug interactions

    • Vitamin K + warfarin (Coumadin) = bleeding risk.
    • Calcium + thyroid meds = absorption issue.
    • St. John's Wort + many meds.
    • Garlic + blood thinners.
    • Always tell doctor + pharmacist.
    • Drugs.com has interaction checker.

    Get tested first

    Don't guess. Annual blood panel includes Vitamin D, B12, folate. Medicare covers. Cheaper than buying random supplements. Most seniors deficient in something. Targeted supplementation. Quality matters — USP-verified. Whole foods preferred when possible. Vitamin pills don't replace healthy diet.
