When to Take Supplements
- Deficiencies: Only take supplements if diagnosed with a deficiency or under specific conditions (e.g., folic acid during pregnancy, vitamin B12 for those unable to get enough from food).
- Timing: Timing of supplements may affect absorption, especially concerning food and other medications.
