So you did check with or your EP was the one to recommend it. That is good at least they know not going to affect any other drug you are taking.
I mentioned this as there was steady post of taking potassium to help with AF. VFIB, PVCs, AVCs. This really sounded good. But I was told by my EP and HF doctors do not take any supplements or OTC without checking with us. I did that and my EP came back and said your blood test show you are at the high end of potassium so we do not recommend you taking a OTC dosage.

It is called Mexiletine. I take a 150 mg tablet. Which I was told was low dose.
Back in 2015 I had 5 shocks of my ICD/Pacemaker and went to ER. There the cardilogist put me on a drip of Amiodarone. It did work and my tachyacardia stopped along with my PVCs.
But I became concerned with the toxicity of the drug and the fact my EP had not put me on it the hospibital cardilogist did (this is at Mayo Jacksonville). My EP said we can try to slowy wean you off the Amiodarone and we did over several months.
My PVCs did got up but tacacarydia was only non sustanied. The PVCs kept getting worse and magnesium was not making any difference he recommended Mexiletine. He told me this drug was for tachycaria and PVCs reductions but did not have the same toxic affects of Amiodarone. Because of it low toxicity and leaves body quickly you have to take it every 8 hours.
I started taking it and my tachyacaridia reduced dramactically to just here and there for few second to none at all (my heart is monitored by my ICE/Pacakemaker which sends report to Mayo every 3 months). My PVCs were cut in half per my EP.
I hope this helped. Sorry for long post but wanted to post what got me to this medication and why.
If your kidneys are healthy, they will excrete overabundances of elements like Mg. The formulation doesn't matter because the liver and kidneys, not to mention other cells that need the Mg, will strip what they want/need and let the rest pass by in the blood stream. What matters is that you do supplement if you're not getting it from food. So, taking it in smaller doses is okay, but largely unnecessary. You can take the single pill if it's more convenient to do that, and it will be safe to do so once in every 24 hours.
The various formulations have some efficacy specificity, meaning they are better for some conditions than others, although the evidence is not hugely strong. The citrate formulation is the most easily absorbed, and it's dirty cheap. Just watch how much it takes to get your bowels moving so much that it becomes a problem; the citrate formula has that side-effect. I have taken citrate, bis-glycinate, and malate formulations, none with any detectable side-effects.

I take 1/2 teaspoon magnesium citrate mixed in about a quarter glass of warm water daily. It's a product called
Calm and I use it in a powder form, unflavored. Doesn't taste bad at all. I take it each evening before going to bed. For me, it reduces ectopic heartbeats (PACs and PVCs). I do not experience any digestive issues or other noticeable side effects from the Calm product.

Without the EXA Test will you really know from just a serum blood test? Even a RBC test. And good luck getting either from a regular PCP. I haven't had luck. Usually IF I ask for a certain test I get it, not the case with Mg, don't know why they refused.
I started supplementing with Mg about this time last year, and for several months to boost my levels. I took the 420 mg TWICE daily so 840 mg. Did that for maybe 3-4 months and now taking the 420 mg in the evenings. I buy the QUNOL 420, which is really marketed as the male doseage, although I'm female, and still from January this year, I had to request them to test it, was 2.0 and 2.1 early April and fast forward to end of July 2025 was 2.1. So levels don't move very quick, or at least they haven't in me, according to my blood tests.
My Nurse Navigator, after 2 closely timed ablation/touchup/watchman, 7 weeks apart, has pretty much only recommended supplementation with Mg and staying hydrated. They haven't pushed all the other things you might read about online to try like Taurine, L-arginine or Potassium supplements. So Mg, excellent hydration along with my D3 is about it for me these days.
@713j Magnesium Glycinate, 200 mg. daily. I have had only a few "episodes" of A-fib since I was diagnosed a little over a year ago. I avoid alcohol, drink 1/2 caf coffee (that is one thing I just could not give up), limit any chocolate, lost weight and exercise every day. I am scheduled for an ablation in 14 days, but who is counting! 🙂 I just want to feel reasonably "normal" again. Good luck.
@sjm46 I'm happy to see you eager for your ablation. Once I read up and understood what it could do, including freeing me of both symptoms and the need to take metoprolol, I did everything but make a nuisance of myself with my cardiologist to help me to see an EP. I'm pulling for ya!
@janetbender The evening is a good time to take it, along with statins (if you are taking one or about to). The thinking is that Mg helps to calm the system and to encourage sleep. Some sleep aids contain 150 mg of Mg, for example.

@gloaming
I have ET and was recommended to take 133 mg Magnesium Glycinate every evening.

Yes! You and my doc agree. Mag glycinate and atorvostatin at nite.
