The score explained

evidence, testing and value, weighed before price

Why 7.8 of 10: The category-defining brain magnesium. Patented Magtein with a human cognition trial, but early and pricey.

what’s good
  • Patented Magtein form
  • Backed by a human cognitive trial (44 adults, 50-70)
  • Less laxative than other forms
worth knowing
  • Evidence still early
  • Three capsules per dose
  • Expensive per day

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.

reviews

4.5· aggregated across retailer sites

The most-discussed magnesium on the list: many report clearer recall and an easier time concentrating after a few weeks, and some notice nothing at all, which tracks with the early evidence. Three capsules a day and the price are the common gripes. Sleep effects are a happy side note for some.
