Magnesium, can anyone tell me the differnce between magnesium oxide, citrate, chilated?

I want to try a Mag supplement but cant figure out which to buy, whats the difference between, magnesium oxide, citrate, chilated,bisgylcinate/citrate? trying to get rid of some buzzing and vibrating on my chest , back and legs, your input would be greatly appreciated

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: http://www.efsa.europa.eu/cs/BlobServer/Scientific_Opinion/afc_ej718_bisglycinates_sum_en.pdf?ssbinary=true

greetings, dorit

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.

LupnerRN,

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,
