Our verdict
Life Extension Neuro-Mag Magnesium L-Threonate works out to $0.34 per serving of magnesium l-threonate, at 144mg per serving in capsule form. That puts it below the median of the 15 magnesium l-threonate products we can price per dose, where the typical serving costs $0.34, a Value Index of 1.0 where the median product is 1.0. One container lasts 90 days at the label dose of 1 serving a day, about $10.26 a month. We could not verify a third-party certification for Life Extension in a public registry.
