Bests & Worsts Reviews from Amazon

I am extremely disappointed. I was ecstatic to find an affordable source of Magnesium Glycinate from a seemingly trustworthy brand, but no longer. They have quietly switched out their formula to a proprietary blend (meaning they refuse to disclose the ratio of individual ingredients) containing the incredibly cheap laxative magnesium oxide. Magnesium oxide is not known to have many of the benefits magnesium glycinate confers as it passes right through you, hence the laxative effect. This supplement is no longer worth the label it's wrapped in and is potentially dangerous to unsuspecting consumers who believe they are reaping the benefits of bioavailable magnesium. Shame on Zhou Nutrition!
