Magnesium seemed to have worked for me

I am so glad that so many of you have posted about magnesium supplements.  It got me thinking and I did some investigating and found the National Institute of Health ( website to be quite helpful.  On the page about magnesium it says "The diets of most people in the United States provide less than the recommended amounts of magnesium." and "Extreme magnesium deficiency can cause numbness, tingling, muscle cramps, seizures, personality changes, and an abnormal heart rhythm."  After giving this some serious thought, I realized that my usual multivitamin contained a good amount of magnesium but I was very lax about taking them this past year and virtually not at all in the last four months.  So, that could have been my problem.  I started taking the recommended maximum of 350mg /day and haven't had an A-Fib episode since.  That seems to me like it may have been the culprit.  Only time will tell I guess.

    There is a very good section on magnesium in the book "Conquer Your A-Fib" by Lisa White which is available very inexpensively on Kindle. As others have said: don't use the magnesium oxide as it isn't very soluable and don't bother with a blood test because what counts is the magnesium in the tissues. I'm on magnesium now. Hoping to avoid a second bad a-fib episode and cardioversion.

    I haven't taken Potassium yet.  I too am curious how often and when others take it and about calcium too.  I read on NIH that we need 4.7g of Potassum a day.  A banana has 930mg each so that too seems like you really need to work at getting enough.  They did check my Magnesium level when I went in the hospital and it was at the low end of the normal range.  So, I am not too sure if that was my cause of AFib, however when I mentioned to my Dr. he said it was fine to take and certainly wouldn't hurt.

    How much potassium are you taking and what is the brand name you are using? I have never taken potassium before and need this information.

    I see that many people take magnesium with calcium and or with potassium.  I wonder if I am short on those two things as well.  This could take some work figuring out what I consume regularly and what I could be short on.

    Well, I live just across the border in Canada and we have a brand here - Jamieson.  They have a good reputation here.  I don't know if they are sold in the US. went to the store and bought some and didn't give too much thought to what brand or what kind.  At that point, I just wanted to get some in my system to see if that was the culprit of my AFib.  Its Magnesium Oxide so maybe there is something better for the long term.  Actually, I intend to create a food list of the amount of magnesium in the usual foods I eat and get most it from food.  Again, on the NIH web page they provide a comprehensive list but it HUGE!  244 pages and very small print.  That is when I shot to the store and bought supplements.  Looking at that list also is what made me think it was the root of my AFib episode.  I had surgery in August and had to stop taking my daily multivitamin.  Then I fell out of the habit.  I also switched my diet a bit and must have missed my sources of magnesium (peanut butter for one thing).  Four months later I find myself in ER.

    It is the oxide type.  I’v decided I need to switch as I have been having some bowel issues.  Never considered it could be the type of magnesium I am taking!

    I’m curious about the dosage?  I take 400 grams but am wondering if’s too much.?  I have an upcoming appointment with my cardiologist and will check with him.

    Taking magnesium every day is one thing that I consider non-negotiable. However, I personally prefer to take magnesium as a separate supplement rather than as part of a multivitamin so I have more control over it. (I ditched multivitamins decades ago in favor of tailoring my supplements to my current needs.)With the magnesium, I order a replacement bottle or two when I have half a bottle left, but am considering setting it up as auto-replenish (I order using Amazon Smile, which is just like regular Amazon but donates a percentage of my purchase back to our non-profit, Magnesium glycinate and magnesium taurate are the two most commonly recommended forms for those with afib, and both have less bowel disruption than other forms such as oxide, citrate, etc. But most who recommend magnesium recommend that you start slowly and build up gradually so that you can tweak as you go along. They also recommend taking potassium with the magnesium as they work together. Regarding testing, I've heard that you need the intracellular magnesium test rather than the magnesium tests that doctors can order.Mellanie
