Why Supplement Quality Matters
Not all vitamin and mineral supplements are created equal. Key factors include:
- Form matters: Magnesium oxide absorbs poorly; magnesium glycinate is far superior
- Dosage accuracy: Some products underdose compared to label claims
- Additives: Fillers, artificial colors, and allergens vary widely between brands
- Third-party testing: Independent verification ensures what's on the label is actually in the bottle
