Actually this is a two part question: I have been trying several magnesium supplements over the years and have only tolerated one so far (which is not produced anymore and, with the knowledge of today, I question if any of the contained Magnesium oxide was absorbed at all. But it certainly produced loose stools if taken in elevated amounts…lol). I tried m. oxide, citrate, phosphate, malate, carbonate and chelated magnesium (don´t recall what it was chelated with though). All of them gave me adverse reactions like throwing up, heartburn, bloating and/or loose stools when taken in or even below recommended dosage. However, I am pretty sure due to oftentimes very elevated stress levels, I cannot have enough magnesium in my system so that the adverse effects (esp. loose stools) could have been attributed to “eliminating the excess”. Do you have any idea what could be behind this problem? Now I was looking for a Magnesium bisglycinate product to try. But it seems that all Magnesium bisglycinate products I can find in Germany online or in my local pharmacy contain Magnesium citrate. On the ingredients´ list they either state: Magnesium bisglycinate, coating agent: hydroxypropyl methyl cellulose (capsule), filling agent: microcrystalline cellulose, magnesium citrate, magnesium carbonate. Or they state the amounts of magnesium and glycine, but also say that the magnesium is available as magnesium citrate or carbonate. This confuses me. Do I have to understand that in magnesium bisglycinate it is not the magnesium itself that has been double glycinated but that it is a magnesium salt to which the glycine has been added? Regarding the above mentioned adversities I experienced with m. citrates and carbonates, would you suggest not to try a bisglycinate product based on those magnesium salts? I know you said you wouldn´t recommend any brands, but if there is a “pure” m. bisglycinate on the market (or one based on different magnesium salts), could you please give me a hint what brand/names to look for? Thank you so much and sorry for the long question.

I have been trying several magnesium supplements over the years and have only tolerated one so far (which is not produced anymore and, with the knowledge of today, I question if any of the contained Magnesium oxide was absorbed at all. Yes, to some degree But it certainly produced loose stools if taken in elevated amounts…lol). I tried m. oxide, citrate, phosphate, malate, carbonate and chelated magnesium (don´t recall what it was chelated with though). All of them gave me adverse reactions like throwing up, heartburn, bloating and/or loose stools when taken in or even below recommended dosage.

Do you have any idea what could be behind this problem? Nothing to do with eliminating the excess, Magnesium is a laxative in most forms (i.e Milk of Magnesia) Now I was looking for a Magnesium bisglycinate product to try.

Do I have to understand that in magnesium bisglycinate it is not the magnesium itself that has been double glycinated but that it is a magnesium salt to which the glycine has been added? If I understand your comment/question, Magnesium bisglycinate is magnesium, and yes it is complexed with glycine to make it more bioavailable Regarding the above mentioned adversities I experienced with m. citrates and carbonates, would you suggest not to try a bisglycinate product based on those magnesium salts? I know you said you wouldn´t recommend any brands, but if there is a “pure” m. bisglycinate on the market (or one based on different magnesium salts), could you please give me a hint what brand/names to look for? All magnesium products contain flow agents, fillers, tableting agents, etc (see above) and many have other magnesium salts added as well . Pure Encapsulations has a Magnesium glycinate that only has a little ascorbic palmitate added, so does Natural Factors
