Can vitamin D supplements cause atrial fibrillation?
It appears unlikely. In fact, a study from Finland suggests that vitamin D supplements could actually help reduce the risk of AFib in older adults.
Should I take magnesium if I have AFib?

However, the study did not look at magnesium supplements that people can take at home.
Therefore, it is essential to consult a doctor before taking any supplements with AFib.
What is the best vitamin for an irregular heartbeat?
Some studies suggest there may be a link between certain vitamin and mineral deficiencies (magnesium, selenium, and vitamin C) and the risk of AFib.
However, studies have not proven supplementing helps with AFib. More studies are necessary before making recommendations.
When possible, it is preferable to get nutrients through the diet, but a doctor can help determine if a person needs additional supplementation.
People with AFib need to be wary about using a number of supplements, including omega-3s, vitamin E, and St. John’s wort.
These supplements and others could hinder the effectiveness of AFib medications, while some could put people more at risk of AFib progressing.
If someone with AFib is considering taking a supplement, they need to discuss it with their doctor first to ensure it won’t affect their treatment plan.
It is preferable to get nutrients through diet whenever possible, but a healthcare professional can help determine whether supplementing vitamins or minerals may be beneficial.
