Episode notes
Case: Middle-Aged Patient Asking About Vitamins
- Patient James Lynd, age 46, asks about taking a multivitamin for general health during a routine visit.
- His risk factors (hypertension, prediabetes, dyslipidemia, obesity) prompted discussion of broader preventive measures.
Widespread Use But Unclear Benefit
- Many people take supplements but the evidence linking them to lower cardiovascular disease or cancer is inconsistent.
- The USPSTF found lots of trials but could not conclude a net benefit for most vitamins and minerals.
Talk Before You Start Multivitamins
- Do not assume multivitamins prevent heart disease or cancer; evidence is insufficient.
- Discuss supplement use with a trusted clinician rather than self-prescribing for prevention.
