Episode notes
Always Supplement With B12
- Take a B12 supplement daily (100–500 mcg) instead of relying on fortified foods alone.
- B12 prevents anemia and reduces dementia risk, so don't skip it even on a plant-based diet.
Supplement Vitamin D If Sun Is Limited
- Take about 2,000 IU of vitamin D daily if sun exposure is limited.
- Vitamin D helps calcium absorption and protects bone health in seniors.
Check Iodine And Thyroid Status
- Consider iodine (RDA ~150 mcg) if you use non-iodized salts or eat little seaweed.
- Test thyroid function with your doctor if you feel fatigued, have hair or skin changes.
