The reason why Magnesium comes up so much

A recent comprehensive article on Magnesium concluding with ' A greater public health effort is needed to inform both the patient and clinician about the prevalence, harms and diagnosis of subclinical magnesium deficiency.' Published Nov 2017

It would be nice to see a more reliable test readily available in the UK as described. The best test, not really good enough, I have found is the red cell test done by BioLab in London. Anybody know how to access a better one?

Biolab have been around for many years and have a good reputation for reliable testing.I cannot answer about magnesium as such.

Thank you for your reply, Yes I know they are good as used them many times, however I think the most accurate they do is the Red Cell test, which is not as indicative for AF as some.

Fascinating reading. I will investigate Thriva lab on the Surrey business park.

Thanks for your reply Peddling, hope all OK with you, I hadn't heard of Thriva do let us know if you turn anything interesting up. Coincidentally, I go to SBP every week as I have started walking basketball at the Sports Centre next door.

Quite a heavy read through that report, but I have copied several passages to print off and keep. It is well worth reading, and thinking about.

Thanks for posting this most informative article. I have been taking approximately 1000mg daily magnesium glycinate to help with AF, with the approval of my EP. I continue to take this level of supplementation post-ablation and I am in the process of getting an RBC blood test to get a better handle on whether I am magnesium deficient despite serum blood results that suggest my magnesium levels are ok. This has been prompted by questions about low potassium levels during acute AF episodes and possible kidney leaking potassium. My nephrologist acknowledges potassium is being leaked but kidneys working fine. So, the issue of magnesium deficiency, in my case, has not been fully explored in this context. Again, this article is a must read AFers and more research greatly needed.

I love dairy and am slowly reducing my intake as I understand a lot of Ca can block Mg absorption.

Presumably pointless doing an assay while you are on supplements?

This test would provide serum and cellular concentration of magnesium and allow assessment based on current level of supplementation, so probably not so pointless?
