Good magnesium citrate

Posted by odereviews on Nov 23, 2013

Cheap and working magnesium citrate. Capsules are large, but I've seen much larger. I like capsule versions, because they are much faster to take than mixing with powders. I take this twice a day.

Good stuff!

A good, cheap magnesium that works. Relieves the shortness of breath and fatigue that goes along with a magnesium deficiency. I've tried other brands that have no noticeable effect on my symptoms. I'm loyal to this brand. Best used in conjunction with a form of transdermal magnesium.
