Why It Matters

An estimated 50% of Americans don't meet the daily magnesium requirement through diet alone. Deficiency is linked to poor sleep, muscle cramps, anxiety, and elevated stress hormones. Chelated forms (glycinate, malate) absorb significantly better than cheap oxide formulations.

Our Methodology

How We Rank Products

Third-Party Certifications

Products with NSF Certified for Sport, USP, Informed Sport, or IFOS certification receive the highest marks. These programs conduct unannounced audits and independent laboratory testing.

Ingredient Quality & Form

We evaluate the bioavailability of the form used (e.g. magnesium glycinate vs. oxide), dose accuracy, absence of unnecessary fillers, and whether the formulation matches the clinical literature.

Label Transparency

Full ingredient disclosure with no proprietary blends. We penalize products that hide doses behind marketing language, and reward brands that publish full Certificates of Analysis.

Value for Money

Price per serving is assessed relative to potency and certification level. A premium-priced product must justify the cost with meaningfully better quality — otherwise a well-priced alternative ranks higher.
