Thorne Iron Bisglycinate 25mg vs Life Extension Neuro-Mag Magnesium L-Threonate

Thorne Iron Bisglycinate 25mg: Thorne Iron Bisglycinate is the gold standard for gentle iron supplementation. The bisglycinate chelate causes dramatically fewer GI side effects than ferrous sulfate — the form most commonly prescribed by GPs. NSF Certified for Sport ensures purity, and Thorne's pharmaceutical-grade excipients (leucine instead of magnesium stearate) reflect their premium positioning. The main drawback is price.

Life Extension Neuro-Mag Magnesium L-Threonate: Life Extension Neuro-Mag features the patented Magtein form, the only magnesium shown in published research to cross the blood-brain barrier. Developed by MIT scientists, it targets cognitive function rather than general magnesium deficiency. The trade-off is cost: at 3 capsules per serving with only 30 servings per bottle, it is the most expensive magnesium supplement in this comparison by a wide margin.
