Reading guide

How to read this shelf

Magnesium in several salts (glycinate, bisglycinate, L-threonate, malate). Labels may give the elemental magnesium or the weight of the whole compound, and the catalog does not record which. Treat the figure as the label's number.

Check on every label

  • Whether the label says 'elemental magnesium' or gives the compound weight (for example '2,000 mg magnesium L-threonate').
  • The salt form named. Different salts contain very different shares of elemental mineral.
  • Capsules per serving. Several products use two or three.

Verdict: Cheap and cheerful magnesium glycinate that costs almost nothing per day, but the score reflects a real transparency problem: no third-party testing and no public lab certificate. The 2200mg listed dose is compound (glycinate salt) weight, not elemental magnesium, so the actual magnesium content is much lower than the label suggests.

The catch: No third-party testing and no public lab certificate, which caps the quality transparency at 6.0.

Verdict: This Life Extension Neuro-Mag Magnesium L-Threonate scores 7.7, making it a strong scorer. It delivers 144mg of Magnesium, 72% of the studied range low edge (200mg) with grade A evidence (strong human trial data). At $2.08/day it's among the more expensive options in Mineral.

The catch: Magnesium (144.0mg is 48% of the 300mg trial dose) is significantly under-dosed.
