Not sure if there is any effect or not. This form of Magnesium seems hyped. In the literature I have read, various other forms of Magnesium supplementation will raise the CSF levels as well. However, at least Doctor's Best are providing us with these rarer kind of substances. I just give this 4 stars since I do not notice or feel anything and I am a very sensitive person.

Helps you study more efficently

at very first night I started notice that my dreams came much more vivid and realistic. Im studying a lot and my concentration has improved. I would say that effect is like +10%. Not much but for me this is very important.

This really gives deeper relaxation than any other form of magnesium. Especially your lung. You get the feeling of deep breathing. Just one capsule is enough to feel the effect. I swallow one capsule after a meal.

Good Product NO GMO's

Posted by MarieMR on Jan 10, 2016

I brought this because the Mercola brand had gone way up in price.This is a good product but did not give me the same effects as the Mercola Brand. So when I can afford it I will buy the Mercola Brand as it is good and also now I see that Iherb has reduced the price on the Mercola brand, yeah! iHerb has good customer service and fast DHL delivery Thanks!

To me it works just fine, I used to take magnesium citrate in the past. To my wife the dosage seems to be high as it gives her the laxative effect.
