Use supplements to fill nutritional gaps, not to maximise the percentage printed on a label.
Before taking multiple supplements together, calculate the total daily intake from all products, particularly for:
- Vitamin A
- Vitamin B6
- Folate
- Vitamin D
- Calcium
- Magnesium
- Iron
- Zinc
- Selenium
- Iodine
- Potassium
For people taking several supplements, a doctor or pharmacist can review the complete list for duplication, interactions and whether blood testing is appropriate.
