Background Check

Jarrow Formulas, a popular nutritional supplement company, brings MagMind to us for cognition support. The main weapon of MagMind is magnesium L-threonate, the only form of magnesium said to demonstrate promising research. This revolves around its ability to readily cross the blood-brain barrier, providing significant benefits on cognition, memory, as well as overall brain health.

Peddling “significant high magnesium brain-bioavailability,” MagMind contains 2 grams of Magtein for every serving for the support of short- and long-term memory. The suggested usage is three capsules a day, or 2 in the morning and 1 in the evening. It can be taken with or without meals, or as directed by your doctor.

Formula Highlights

Supplement Facts

Key Ingredients

The key ingredient of this nootropic is magnesium from Magtein Magnesium L-Threonate, amounting to 144 mg per serving or 35% of daily value. Its other ingredients are magnesium stearate (vegetable source), cellulose, and silicone dioxide, with the capsules consisting of bovine gelatin.


The unwavering focus on magnesium L-threonate is a laudable one. This gives MagMind a unique differentiator, something that offers a unique approach to brain enhancement since not all brain enhancing supplements contain magnesium as a primary ingredient. This, however, poses a problem for those who (1) have issues with magnesium intake, (2) don’t get the ideal benefits from the amount per serving, or (3) want synergistic action from different nootropic ingredients, thus the work nootropic stack.

Effects and Benefits

The main premise of MagMind is supporting cognition and brain health. Now, how it does this is a bit tricky, as the product copy focuses on a very spare writeup plus vague claims on “crossing the blood brain barrier” and providing “significant positive effects” on areas of purported benefit. What does this process translate to? How does the user gain cognitive support in the process? Where are the clinical results? The answers seem to be lost in a maze of endless adorations of magnesium, or are nonexistent after all.

Rating: 11.5/20

Potential Side Effects

Exisiting literature on supplements hail magnesium L-threonate as a generally safe ingredient, except with inappropriate use or excessive dosing. The documented side effects of MagMind then remains sparse and manageable.

Rating: 18/20

Pricing Options

The price of MagMind is in the vicinity of $26 for a single 90-capsule bottle, a price tag that competes well with other magnesium supplements found in the market today. Compared to other nootropics in general, it still fares well and remains competitively priced.

Rating: 19/20

Online Reviews

As of this writing, MagMind has nearly 300 customer reviews on Amazon, which average 4.5 out of 5 stars. That’s an above average rating, one that bodes well for a magnesium supplement like this one. We can’t help but notice, though, the mixed reviews when it comes to its effectiveness, with points against variabilities in effects based on different bottles, as well as a state of anxiety and agitation that can follow intake. These bring about a fair warning, particularly for those who don’t react well to magnesium.

Rating: 14/20



  • Priced competitively compared to magnesium counterparts and other nootropics
  • Minimal documented side effects
  • Fairly good market reputation (including market presence of manufacturer)


  • “Just magnesium” – doesn’t leverage benefits from common nootropic ingredients
  • Perceived variability in MagMind’s effects based on different bottles
  • Lack of clinical study to vouch for effectiveness

Our Verdict

MagMind is clear about its intent and solid in its nootropic game plan, which is to use magnesium for cognitive and brain health support. Our main problem with it is the general tendency to praise magnesium as a cure-all, a magic bullet that can address all types of maladies including brain and memory issues. This isn’t how nootropics work, which is why many users rely on stacks to get maximum benefits and effects for their study/work/active lives. When magnesium fails or falls short, where does MagMind fall back on?
