NOW Foods Zinc Picolinate 50mg vs Life Extension Neuro-Mag Magnesium L-Threonate

NOW Foods Zinc Picolinate 50mg: NOW Foods Zinc Picolinate delivers a therapeutic-strength 50mg dose in the highly bioavailable picolinate form. Well-suited for short-term immune support or correcting deficiency, but the dose is arguably too high for indefinite daily use. Long-term high-dose zinc supplementation can deplete copper levels, so cycling or pairing with copper is advisable.

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.
