Reviews From Some Of Our Happy Customers




I have been taking these for about one year. I keep re-ordering because I sleep so much better and it is part of my menopause, journey, health tool kit!
VERIFIED PURCHASE
Excelente suplemento, he notado una gran diferencia en mi concentración y memoria desde que lo tomo. También duermo mejor y me levanto con más energía. Muy buena calidad y fácil de digerir.
VERIFIED PURCHASE
The product arrived in perfect condition, the delivery was fast. What is indicated in the information is what the product indicates. Since I have been taking the product it has given me energy, and in my rest time I can rest my 8 hours a day. Excellent product, I recommend it to everyone.
VERIFIED PURCHASE
After asking chatgpt what supplements may help with memory issues, Life Extension Neuro Mag L-Threonate was suggested (among other supplements). I bought three supplements but am only using this one. Almost immediately I felt like my brain jumped back in time 10 years. The brain fog went away, and my word retrieval issues almost disappeared. And I am only taking one capsule a day. I cannot recommend this more highly!
VERIFIED PURCHASE
I track my Ca to Mg ratio, which various sites say should be about 2:1. To keep it in that range, I take mg threonate occasionally, typically 1 on most days. The LEF multi vitamin provides Mg, so with that and food I don't need much. I chose this because it is reported to pass the blood-brain barrier, so I believe it will help maintain brain health. As a senior, my mind had remained sharp, even though some time ago I had a concussion. I immediately took one, and within 20 minutes my brain fog lifted.
VERIFIED PURCHASE
My mom and I both take Neuro-Mag supplements, and we’ve 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 they’re 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 we’ll definitely keep buying it!
