Great Product
Life Extensionâs Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why itâs so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium thatâs specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Hereâs my take on its performance, benefits, and overall experience.Pros:⢠Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonateâs ability to enhance synaptic density and cognitive function, particularly in aging individuals.⢠Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness.⢠High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects.⢠Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice.⢠Trusted Brand: Life Extensionâs rigorous testing for purity and potency gives confidence in the productâs quality. Their transparency, including offering Certificates of Analysis, is reassuring.Cons:⢠Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health.⢠Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience.Final Verdict: Life Extensionâs Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!

Noticeable Improvement in Mental Clarity and Sleep Quality
Iâve been using Life Extension Magnesium L-Threonate (Neuro-Mag) for several months, and Iâm genuinely impressed with the results. I originally chose this supplement because it’s one of the only forms of magnesium that crosses the blood-brain barrier, and I was hoping it would help with brain fog and sleep quality.After about a week of consistent use, I noticed a subtle but definite improvement in my mental clarity and focus. I also sleep more soundly and wake up feeling more rested, without grogginess.The capsules are easy to take and havenât upset my stomach at all, unlike some other forms of magnesium Iâve tried. Itâs a bit more expensive than standard magnesium supplements, but for me, the benefits are worth the cost.

Noticeable Boost in Clarity and Focus, Worth It!
My mom and I both take Neuro-Mag supplements, and weâve noticed a clear improvement in mental clarity, memory, and overall cognitive sharpness. It really helps with brain fog! Within a week or two of starting, we could both feel a difference in how quickly we processed information and stayed focused throughout the day. The capsules are a bit larger, but theyâre manageable and totally worth it for the benefits. We also appreciate that it’s affordable compared to similar magnesium options out there. This supplement has become a staple in our routine, and weâll definitely keep buying it!

Better sleep and no more brain fogâworth it!
I bought this because I was struggling with restless sleep at night. I read that magnesium could help, and I wanted something easy to absorb without upsetting my stomach.When it arrived, the packaging was clean and sealed properly. The capsules are a good sizeânot too bigâand thereâs no weird smell or aftertaste.â What I like:-Helps me relax and sleep better-No digestive issues (unlike other magnesium I’ve tried)-Vegan-friendly and doesnât contain unnecessary fillersâ ï¸ What could be better:- I found no issues with this productWould I buy it again or recommend it? Absolutely. This has become part of my nightly routine, and I notice a difference if I skip it.Overall, this magnesium supplement is high-quality, easy on the stomach, and works, especially for sleep and muscle recovery.

Another Winner from Life Extension
I was originally recommended this magnesium from my neurologist after suffering a head injury. Magnesium is widely recommended by physicians of all scopes, as it helps regulate the cardiovascular system and electrical activity across the body. This particular magnesium is bound to an amino acid, L-threonate, which allows it to cross the blood brain barrier before being dissipated. I canât speak to the effectiveness of the biotechnology quite as well as Iâve had less feedback (EKGâs, etc.), but I feel much better on it.It can help with sleep consistency as well. I take one at lunch and one at night. Paired with glycinate, this makes the ultimate magnesium supplement.It greatly improved my symptoms after consistent intake. I have been taking it for nearly 3 years and highly recommend, even if your health is normal. LE is also a well-regarded brand for cognitive performance supplements, and this is proof why.

Missing capsules in the bottle
I have order this product three times and each time the bottles have been short by one capsule. instead of x90 capsules, I have only received x89 capsules each time. I suggest counting your bottle upon receiving.
