I use this stuff stricly as an additive to my flavored water while playing tennis.
I used to use some citrus flavored magnesium tablets given to me by some friends from Germany and I guess I must have gotten used to them because, when my supply ran out....my game went down the tubes...seriously! I wasn't connecting with the ball as sharply anymore...there was some apparant disconnect which I couldn't put my finger on until another friend offered me their supply of the magnesium tablets and as if by wizardry...once again, my game returned....until their supply ran out and....same disconnect returned. So I figured, all else being the same...I must need this magnesium supplement big time....searched the net for something I could pour into my water, like the aforementioned tabs, which incidentally I did find on the net but I couldn't figure out how to buy them since it was a German website, in German and priced in Deutsch marks or something??? No clue!
So when I found this liquid version, perfect for adding to my water....I jumped on it. Well, it ain't no citrus flavored product...much more shall I say "metallic tasting" but....I got used to it and, yep...game is back on!
I am on my third or fourth bottle at this point..I just add a tiny bit to a water bottle..really just a little, tiny amount and then either some MIA water flavorer or some other water flavorer and I am good to go!
If you read up on Magnesium, especially Magenesium Glycinate, you will find that it supposedly does in fact help with neuron trasfer and brain function/synapse connectivity...which apparantly I lack without it...at least playing tennis anyway???
