Neuro-Mag® Magnesium L-Threonate from Life Extension

90 vegetarian capsules / 30-day supply

RECOMMENDED USE: Take three (3) capsules daily with or without food, or as recommended by a healthcare practitioner. Magnesium L-Threonate has less of a laxative effect than other forms of magnesium.

Available online only.
Neuro-Mag® Magnesium L-Threonate supports healthy memory and cognition by optimizing magnesium levels in the brain. Magnesium is essential for over 300 different biochemical reactions in the body — from cardiovascular and bone health support to energy metabolism, mood, and most especially cognitive function. Unfortunately, it’s hard to maintain optimal levels of magnesium in the brain. And that’s a problem since magnesium deficiency increases with normal aging. But because of its superior absorption into the bloodstream and nervous system, Neuro-Mag® provides the ideal form of magnesium for enhanced memory and cognitive function.

Benefits at a Glance

Supports healthy memory and cognitive function
Optimizes magnesium in the brain
May maintain the quantity and quality of synaptic connections between brain cells
Supports important brain cell signaling pathways essential to cognitive health
Supports Healthy Memory and Cognition

Magnesium is needed for more than 300 biochemical reactions1 and 600 enzymatic reactions2 in the body. In addition to support for cardiovascular3-10 and bone health,11-14 energy metabolism,15-17 glucose metabolism,18-22 mood,23-26 sleep,27-29 and vitamin D status,30-32 researchers are now focusing intensely on magnesium’s benefits for cognitive function.33-38

Magnesium L-threonate is a unique form of magnesium that is delivered into the brain where it maintains the quantity of synaptic connections between brain cells33,34 and supports important brain cell signaling pathways essential to cognitive health. One of the key benefits of increased brain magnesium levels is improved memory.33-38 In compelling animal models, the magnesium L-threonate contained in Neuro-Mag® improved short-term memory by 18% and long-term memory by 100%.33

Optimizes Magnesium in the Brain

Worldwide, nearly two thirds of the population lack the recommended amount of magnesium in their diet,39 whereas in the US it is closer to half the population.40 Older populations are also at a higher risk of magnesium deficiency.28,29,41-44 Don’t be one of them! Unfortunately, it’s even harder for your body to maintain optimal levels of magnesium in the brain.33 This problem is of special concern for maturing individuals, as magnesium deficiency increases over time.45

Most commercially available magnesium supplements are not readily absorbed into the nervous system. To overcome this obstacle, supplement with this innovative form of magnesium, shown to specifically target the aging brain and nervous system. In pre-clinical models, the magnesium L-threonate contained in Neuro-Mag® boosted magnesium levels in spinal fluid by an impressive 15% compared to no increase with conventional magnesium.33

Support your memory with just three capsules a day

Try Neuro-Mag® Magnesium L-Threonate in a bottle of 90 vegetarian capsules for a one-month supply. The suggested daily dose of three capsules provides 2,000 mg of magnesium L-threonate. While this supplies a modest 144 mg of elemental magnesium, its superior absorption into the bloodstream and nervous system makes it the preferred form of magnesium for enhanced memory and cognitive function.

3 reviews for Life Extension Neuro-Mag® Magnesium L-Threonate


    I would buy this product again
    Helps with my memory,I can remember more since I started with Neuro-Mag magnesium L-Threonate.

  2. VitaminPro65

    Memory Booster
    Over the years, many supplement products have claimed to boost memory. Results were often very mixed, and often poor. Now, we have this “brain magnesium”, developed by researchers at the world reknonwed M.I.T. This unique form of magnesium has a special affinity for collecting inside the brain. In the five+ years it has been on the market, I have seen this produce consistently excellent results…more so than any other “memory booster supplement”. And I have been selling supplements for 25 years. That speaks volumes!

  3. Donna the Healthinator

    Love this product!
    I take this before I go to bed daily. I feel it helps me sleep more soundly and it relaxes me. I also notice my memory is improving; even others have noticed this as well. I will definitely keep taking this.
