Bests & Worsts Reviews from Amazon

Like some have already mentioned. I too bought this thinking this was just Magnesium L-Threonate, due to the wording on the title of the product page. When in reality it's actually a magnesium complex. That alone wouldn't have been a big deal, but the issue here is the MAGNESIUM OXIDE. A significant percentage of the population are sensitive to magnesium oxide, myself included. Yet magnesium oxide isn't even listed on the label, you have to really look for it line by line on this product page to find out that it does contain magnesium oxide. This ended up inducing extreme nausea the only two time I've taken it. I gave it another go on a different day after I vomited my guts out the first time, hoping that it was just something else I ate. So after isolating all the variable I could think of, this thing still gave me debilitating nausea. So now I have a useless big bottle of this stuff that I've only taken 4 pills out of. Obviously your mileage may very. But if you know that you're sensitive to magnesium oxide, STAY AWAY!
