Vitamins Your Doctor Recommends

Nutrient deficiencies are common among older adults due to changes in absorption, diet, and medication interactions. Your Medicare Advantage OTC benefit covers most essential vitamins and supplements — here's what to prioritize.

Additional Beneficial Supplements

Doctor's Advice: Before adding supplements, tell your doctor — some interact with prescription medications. Vitamin K can interfere with blood thinners, and calcium can affect thyroid medication absorption.

How to Maximize Your Allowance

Vitamins are one of the best values in the OTC catalog. A 90-day supply of Vitamin D3 costs $5-8, B12 costs $6-10, and a senior multivitamin costs $8-15. You can stock up on 3-4 essential supplements per quarter and still have allowance left for other products.
