Great

Title: Great Brain Magnesium – Really Works! Rating: ⭐⭐⭐⭐⭐ Review:
Metagenics Magnesium L-Threonate is a standout. I’ve tried many magnesiums, but this one actually reaches the brain. Within days, I noticed sharper focus, quicker recall, and a calmer mood — especially at night. No grogginess, no stomach upset, just clean support. Capsules are easy to take, the bottle lasts a month, and iHerb delivered fast to Greece. Trusted brand, pure ingredients. Worth every penny for cognitive health. Highly recommend! 🧠💡

Good

Mag L -Threonate it says will help support cognitive health and I am very happy with taking it. Although i notice improvement in my moods and energy level, I did not notice improvement in my cognition.

Great quality. I take one in the morning and 2 in the later afternoon as opposed to the recommended 2 before bed. I find the late afternoon dose is calming and I appreciate that. It’s expensive but so far I’d keep buying it if I can afford to or catch it on sale.

Lifted my mood with these saffron extract capsules. After a few weeks the dark clouds parted. No side effects. The bottle has a mood-boosting yellow label.

High-quality magnesium for focus and relaxation

I’ve been using this magnesium L-threonate for a while and it’s one of the better forms I’ve tried. The quality is noticeable, and it feels more targeted compared to standard magnesium supplements. I mainly take it for relaxation and mental clarity, and I’ve noticed improvements in focus as well as better sleep quality over time. It doesn’t cause any digestive issues like some other forms of magnesium can, which is a big plus. The capsules are easy to take, and the bottle lasts a decent amount of time depending on dosage. It’s a bit more expensive than regular magnesium, but the benefits make it worth it in my opinion. Overall, a great option if you’re specifically looking for cognitive support and calmness. I’d definitely continue using it.

Good Find.

It is always difficult to find a L’Threonate that won’t break the bank. This brand came highly recommend to me. I just started taking this so I don’t have much feed back

Quality

This seems to be a decent quality magnesium Magtein. My wife takes it and sometimes it seems to help with sleep; other times not so much. I think quality can vary a lot with brands.
