Someone may need to correct this but the way I understand it, ending in "ate" is chelated which is good. I believe chelated magnesium is bound with a protein so it is released over time rather than just dumped into the system all at once. Magnesium oxide is the cheapest form of magnesium and not chelated. Magnesium citrate is chelated. There are several other forms of chelated magnesium

hi judy3 -

I buy magnesium citrate as supplement; the oxide is also used in medicine but to my knowledge for helping with stomach acidosis and besides medicine as food additive (No.E 530 in Europe) to prevent different food (like cacao etc) from agglutinating;

I found a study lately about bisglycinate / glycinatnicotinate for mineral supply from the efsa (european food safety authority) - they say it is safe; I prefer supplements which do not need a special study about safety because they were so highly "doped" in the cemestry lab/ in production process.... this scares me a little, just me... - I dont know if the other stuff is safer.
here is the link from them/ their study:

greetings, dorit

My LLMD prefers mag citrate for us GI screwed up Lymies. I guess the ease of absorption is better.

I bought a bottle of mag citrate liquid at Costco for $1.80. And it lasts awhile. I wish all our supplements were this cheap!!

Chelated Magnesium is the best, but may not be as easily absorbed as the citrate form. Magnesium oxide is cheap, but very poorly absorbed. I reacted badly to the bysglycinate form (heart rhythm disturbance), but your experience may be different from mine.


I hope you aren't talking about the Mag Citrate laxative product...if so, it is very, very high in sodium. Check the label and make sure.

Magnesium Citrate in tablet/capsule form will provide magnesium without the excess sodium.

I hope this helps...take care,

I take Magnesium Glycinate, I was told that was the easiest form to absorb. No problems with it at all.  D
