Best Magnesium products by transparent scoring (2026)
Single-ingredient products scored by public rules: dose fit, label transparency, data verification, company transparency, third-party testing. Not a measure of efficacy or safety. No paid placement.
Products ranked: 227 · Reference range: 175 – 350 mg (source) · Updated 2026-11-01
Here the UL (350 mg, supplements only) is lower than the Daily Value (420 mg), so the range runs from half the UL to the UL.
Single-ingredient products only.
