Nature Made Magnesium Oxide 400mg vs Life Extension Neuro-Mag Magnesium L-Threonate
Nature Made Magnesium Oxide 400mg: Nature Made Magnesium Oxide is the budget option — cheap, high-dose on paper, but with the worst bioavailability of any magnesium form at roughly 4-5% absorption. The ingredient list includes titanium dioxide (banned in EU food since 2022), soy, and gelatin. It works as a laxative but is a poor choice for addressing magnesium deficiency or improving sleep, muscle function, or stress.

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.
