Side effects of taking magnesium and Apixoban?

Hello everyone

I have PAF and looking to take magnesium supplements.

Does a anyone out there take magnesium and if so which one?

I have read magnesium citrate is the most absorbable?

Also what daily dosage?

I currently am on Apixoban 10mg daily.

Are there any adverse side effects of taking magnesium supplements with Apixoban?

Thank you for any advice.

Keep well and happy

  • I've been taking 400mg of Mg Glycinate (200mg tablets twice daily) for several years along with 700mg of potassium (V-8 low sodium) and my palpitations have virtually vanished.

  • Hi

    Thank you that is good know but are you taking with anticoagulation medication as well?

  • Yes, I'm taking Xarelto (Rivaroxiban), 20 mg daily.

  • sorry to be a bit dense here, but when you say your palpitations have virtually vanished, do you mean your full on AF episodes or runs of palpitations?


  • I had severe palpitations with or without AF symptoms. Those have gone but I haven't had AF symptoms for over two years. I was diagnosed with sleep apnea and started on a CPAP at about the same time as my AF started going away. My AF is asymptomatic so I can't be absolutely sure. I do exercise regularly and try to watch my weight.

  • My prescript. is like yours mzoren but minus potassium as my natural potassium level is good. I began Mag. about a year ago and Apix. replaced Warfarin 6 months ago and all seems very well,,feeling fine.

  • Feeling fine is great! It sounds like you are doing the right things.

    Good luck,


  • Interesting you mention low sodium v8, as I dont drink it often, but my last 10 hour a fib marathon event, when it suddenly stopped, I craved v8 and luckily had some in the frig. Do you drink it daily and how much? I too am a fan of mag glycinate. Thankyou.

  • I keep 5.5oz (162.7ml) cans of low sodium V8 in the refrigerator and drink one with breakfast every day. I started drinking it for the potassium but it turns out that I like the taste. I also bring some with me when I travel.


  • Thankyou, I believe I will do the same😊

  • I'm glad you asked this because I'm thinking about magnesium. Not much response though! I took a small amount of magnesium citrate for a while - it was one a day and I think they suggested three a day (£££) - and it was perhaps not enough and I didn't notice any benefits. I am now feeling I get too much cramp and perhaps it might sort that.

  • These work out at ~£5 month if you take 3x 200mg a day. I think you'd probably need 600mg or more to make a difference. I take 800-1000mg plus other supplements including 200 potassium.

  • I must be in a tiny minority, but I've posted before on here that the 300mg per day magnesium citrate tablets I started taking around a year ago would appear to have caused symptoms which hindered rather than helped me.

    I found that, about ten days after I started taking them, I started to get far more ectopic beats than normal - at it's worst, I was getting about ten to twelve of them a minute, whereas normally I feel one about every half an hour or so. I carried on taking the tablets for about three weeks with no change in the number of "missed beats" I was getting (I also had an AF episode which was similar in character to the ones I usually get).

    When I tried to figure out what might be causing the extra ectopic beats, the magnesium citrate tablets struck me as the most obvious candidate, so I decided to stop taking them and see what happened. Sure enough, my heart returned to what passes for normal these days within a week or so and has stayed that way ever since.

    I've mentioned what happened to a GP and the nurse who does my INR tests and when I told them that I tend to eat at least two bananas a day, have far more fish than I do meat and now tend to have a handful of nuts or seeds when I feel like snacking, they both said it sounded like I might have been having too much magnesium daily.

  • I take Magnesium Taurate 125mg capsules, manufactured for Cardiovascular Research Ltd, which I get from Amazon. I also take Rivaroxaban. When I first started on them I took 4 a day, but now I only take 1 or 2.

  • I also take Magnesium Taurate 125mg as recommended by Dr Sanjay Gupta in his blog on why Magnesium is so essential for heart health. His blog can be found on YouTube for anyone interested.

  • NiceNana took the words out of my mouth. I was pondering about taking Mg then I saw Dr Gupta's info and now take Mg Taurate, juts one tablet once a day with food. Each time I've been in A&E with PAF they found that I was potentially low in Mg and other salts.

  • Everything I've read has indicated that Magnesium Taurate is the best source of magnesium for heart rhythm. I also take 2 a day (125 each) and my heart has calmed significantly. (Also take apixaban.)

  • I have been looking for Taurate. where did you buy this?

    thanks in advance!

  • I buy it through, but you can also find it at other places, such as

    Good luck!

  • hi Julia,

    I have Magnesium Citrate and Apixaban- no problems- think its 200mg daily
