What to Compare in Magnesium Products
01
Chemical Form
Same ingredient, different absorption. We identify which form each product uses.
02
Exact Dosage
Quality products list exact amounts. Blends hide quantities. We compare what's disclosed.
03
Testing Status
Third-party certification verifies label accuracy. We show which products test.
04
Daily Cost
Serving size affects real cost. We calculate price per day accounting for servings.
Common Comparison Mistakes
- ✗ Sticker price comparison — Two $25 products can have vastly different daily costs based on serving size
- ✗ Trusting front labels — Marketing claims exceed what facts panels support
- ✗ Ignoring ingredient forms — Same name, different chemical compound, different absorption
- ✗ Assuming all products test — Many brands skip independent verification entirely

Frequently Asked Questions
Which magnesium product should I choose?
Compare based on form preference, dosage needs, and budget. Premium forms cost more but might absorb better. Standard forms work for many. Check specifications against your situation rather than trusting rankings.
Why do magnesium prices vary so much?
Ingredient quality, testing investment, marketing spend, and margin. Higher price doesn't guarantee better quality. Calculate daily cost across products and compare specifications, not sticker prices.
Does higher dosage mean better results?
Not necessarily. Some nutrients have optimal ranges. More isn't always better. Research appropriate ranges for your situation.
How do I compare products fairly?
Compare forms (not names), exact dosages (not blend totals), testing certifications, and daily cost (not bottle price). Supplement Comparisons provides specifications for direct comparison.
