Bests & Worsts Reviews from Amazon

I have taken many forms of Magnesium ( glycinate, maleate, citrate) in addition to this formula. It wasn't until I went a few weeks without any Mag Threonate that I noticed my mood, focus and outlook on life was dampened. After reordering this product and taking for a few days, I was back to my old happy self. I am convinced that if you are wanting a Magnesium supplement that helps with many mood and cognitive functions, this is it!! Only downside is price... would be great to have it offered in a bigger bottle!
