what the evidence says
Magnesium L-threonate is the brain-targeted form, built on animal work showing raised brain magnesium and a small human trial suggesting improved cognition in older adults. That human base remains thin and largely industry-adjacent, and no trial shows superiority over cheap forms for sleep or stress. You pay a large premium for an early-stage cognitive hypothesis.
