How to Choose What You Need
The best approach is to get a blood test and supplement based on actual deficiencies. However, some general guidelines:
- Everyone likely needs: Magnesium + Vitamin D3
- Women of childbearing age: Iron (get ferritin tested first)
- Plant-based diets: Zinc + Iron + Iodine + Selenium
- High stress/intense exercise: Magnesium + Zinc
- Thyroid concerns: Selenium + Iodine
💡 Start With the Basics
If you're new to mineral supplementation, start with magnesium glycinate (200-400mg at night) and vitamin D3 (2000-5000 IU in the morning). These two cover the most common deficiencies.
