Mineral Supplements Buying Guide

When shopping for mineral supplements, consider these important factors to ensure you're getting a quality product:

  • Form and bioavailability: Look for minerals in their most bioavailable forms that your body can easily absorb and utilize.
  • Chelated minerals: Consider chelated forms (bound to amino acids) for potentially better absorption and gentler digestion.
  • Dosage: Check that dosages are within effective ranges without exceeding upper limits for safety.
  • Mineral balance: Be aware that some minerals compete for absorption, while others work synergistically.
  • Third-party testing: Choose products verified by independent organizations like USP, NSF, or ConsumerLab.
  • Additional ingredients: Be aware of fillers, artificial colors, allergens, and other additives that may cause reactions.
  • Potential interactions: Research possible interactions with medications or other supplements you're taking.
