Very good product!
Cognitive Magnesium, 90 Vegetarian Capsules (48 mg per Capsule) from Natural Factor producer is a very qualitative product necessarily the persons who have problems with nervous system. This product may contribute to cognitive function and mental health, may contribute to reducing fatigue and mental exhaustion also. From the first days I started taking it, this product had a very good effect on me, relaxing me, allowing me to rest better, and allowing me to concentrate better on my work tasks. I highly recommend it!

Cognitive magnesium is highly recommended. Take two capsules before bed and you'll rest very well. There's no substitute for it. Try it.

Great Product
I'm very happy with the capsules, however take care that even a full serving of 3 capsules only delivers 144 mg of elemental magnesium.

Vynikající!
This is one better magteins available on iherb. While others sometimes bring me headache, this one is ok. It seems it may have some positive effect on my sleep (taking it after dinner)

Good
Magnesium Threonate is slightly more expensive than the other variants partially due to its ability to cross the BBB. I thought I’d give it a try
