Hi there, I recently purchased the Amino Nutrition 100% Pure Magnesium Glycinate Powder 1kg. It was my first time on your website; I was checking out the NutriVital Magnesium Glycinate 400g which I intended to buy two of, I’ve bought it several times from my local health food store, and it’s a great product. But I spotted the Amino Nutrition 1kg Magnesium, and thought I’d try it; seeing as on the bag it says it’s “Pure Magnesium.” I really wanted the product to be good, I really did. I never write negative reviews, but on this occasion I have to because I had such a bad experience with this product! I’ve been Carnivore for 3 years and in the best health of my life, but this product played havoc with my system me for two weeks, I won’t go into all the details, suffice to say it messed with my microbiome big time! When you mix the powder into a glass of water, what is that incredibly sweet granulated substance that forms at the bottom of the glass?! There’s something not quite right about it, that’s for sure. After 3 days I stopped using the product, but it took some for my system to go back to normal.
