Life Extension Neuro-Mag Magnesium L-Threonate Review

Neuro-Mag® Magnesium L-Threonate is sold by Life Extension as a bottle of 90 vegetarian capsules, presented as a best-selling brain health supplement that supports memory, quick thinking, and cognitive health. The page explains that magnesium is an essential mineral for more than 600 biochemical reactions in the body and plays an important role in the nervous system and brain, and it notes that most Americans do not get enough magnesium from their diet and that suboptimal magnesium levels increase with age. Neuro-Mag® contains clinically studied Magtein® magnesium L-threonate, described as a well-studied and absorbable form of magnesium. The product is positioned to promote working or short-term memory, encourage quick thinking, and support overall cognitive health. The page cites a randomized placebo-controlled trial in 44 adults aged 50 to 70 in which a daily dose of 1.5 to 2 grams of magnesium L-threonate showed improved cognitive and executive function in 12 weeks. The suggested daily dose is three capsules, which provides 2000 mg of magnesium L-threonate and 144 mg of elemental magnesium, and one bottle is listed as a one-month supply of 30 servings. The product is labeled gluten free, non-GMO, and vegetarian, and it is said to be manufactured in the USA. The page states that magnesium L-threonate has less of a laxative effect than other forms of magnesium, and that it can be taken at any time of day with or without food. It also notes that the product was designed for adults over 18. The page says that Life Extension tests raw materials and finished products for heavy metals, microbes, disintegration, and potency, and that a certificate of analysis is available on request. The statements have not been evaluated by the Food and Drug Administration, and the product is not intended to diagnose, treat, cure, or prevent any disease.
