Magnesium L-threonate, the form built for the brain

Most magnesium supplements get picked for sleep, cramps, or digestion. Neuro-Mag is different: it uses Magtein® magnesium L-threonate, a form developed specifically to reach the brain and support cognitive function.* Three capsules a day deliver 144mg of elemental magnesium from 2,000mg of Magtein.

What's in the daily serving

  • Magnesium 144mg (34% DV) as Magtein® magnesium L-threonate (2,000mg of the chelate)
  • 3 vegetarian capsules per serving, 30 servings per bottle
  • Vegetable cellulose capsule; no listed gluten or GMO ingredients

Why magnesium L-threonate (and not another form)

Magnesium comes in several forms, glycinate, citrate, oxide, malate, and they are not interchangeable. Each one is absorbed differently and lands in different tissues. Magtein® was developed because most magnesium does not cross into the brain very well, and L-threonate appears to do that more efficiently. That is why people pick Neuro-Mag for cognitive support, not for muscle cramps or digestion.* If you mainly need magnesium for sleep or cramps, glycinate or citrate are usually the better starting points.

What people use it for

The common reasons are memory, focus, mental clarity, and supporting healthy cognitive aging.* If you are expecting fast results, this category tends to be a slow build over weeks rather than days. Consistency matters more than dose stacking.

How to take it

The label calls for three capsules per day. You can take all three at once or split them across the day, whichever sits better. Magnesium L-threonate is generally easier on the stomach than higher-laxative forms like citrate or oxide, so most people tolerate it on or off an empty stomach. If you are pregnant, nursing, or on medications, check with your doctor first.

It pairs naturally with our wider magnesium range; for help choosing between forms, our guide to the best magnesium supplements compares glycinate, citrate, L-threonate, and the rest.

Richard ★★★★★

I was skeptical about yet another magnesium, but the L-threonate form actually feels different from the citrate I used before. Around week three I noticed my afternoon brain fog lifting and I could focus through long work blocks without that scattered feeling. It's a bit pricey for a month's supply,

Charlotte V. ★★★★★

I picked this one up specifically because it's magnesium L-threonate instead of the usual citrate or glycinate, and I actually notice the difference in how clear my head feels by mid-afternoon. Two capsules with dinner has become the easiest part of my routine.

Olivia G. ★★★★★

I’ve tried plenty of magnesiums before for sleep and muscle recovery, but this L-threonate form actually seems to sharpen my focus during the day. The brain-targeting angle with Magtein feels legit—my mental fog lifts about 45 minutes after taking it.
