Magtein Magnesium L-Threonate to Improve Cognition, Focus, Memory, Sleep Quality and Brain Health with Small Caps - 120 Vegetable Capsules

This product helped me immensely with memory and muscle cramps. I have taken it for years now and highly recommend it.

My doctor recommended this in 1 capsule each night to eliminate leg cramps! After less than a week my crippling leg cramps ceased! Wonderful uninterrupted sleep!

This is a better brand than the other brands you purchase from a local store.

My chiropractor suggested these as help with Miagraine headaches and they didn't make them disappear totally but I have way fewer ones and those are usually gone within half an hour!!

Me ha servido mucho para conciliar l sueño.

Excellent supplement; I have used it for 3 months and can feel the positive affects.

Best magnesium for absorption are the threonate and the glycinate formulas. Threonate can cross the blood brain barrier and help with sleep as well as helping with bone building and cell nutrition. Other magnesiums like citrate have moderate absorption and are cheaper but work great for constipation. Magtein is the premiere brand for threonate and is licensed in other great brands like Mercola, Life Extension etc. So i decided to get it from the original manufacturer.

I don't know if it's due primarily to this supplement, but after one month of use, my joints feel better and brain fog has lessened. Will continue using.
