Another vitamin deficiency that can lead to heart palpitations is vitamin B12. Similar to a folate deficiency, a lack of vitamin B12 can lead to anaemia and thereby result in heart palpitations, per the ODS. Vitamin D is another supplement that can cause heart palpitations when taken in large amounts.
Some studies have shown that it's possible to have too high a blood level of vitamin D, which is associated with a higher risk of death from any cause, cancer in areas like the pancreas, and a higher risk of heart disease (NIH, n.d.).
Excess Vitamin D harms the heart - Study
Scientists have long known that low levels of the nutrient can hurt the heart, but new research shows that higher than normal levels can make it beat too fast and out of rhythm, a condition called atrial fibrillation.
A recent study found that taking higher than recommended doses of vitamin D for 5 years may have helped lower participants' risk for an irregular, fast heart rate (atrial fibrillation or AFib).
Conclusions. In conclusion, these findings indicate that vitamin D supplementation might reduce the incidence of major cardiovascular events, particularly myocardial infarction and coronary revascularisation. This protective effect could be more marked in those taking statins or other cardiovascular drugs at baseline.
For less frequent dosage, a higher amount is recommended. Overall, though, studies show that the best results come from taking vitamin D as part of a daily regimen, with dosage at the recommended level.
Vitamin D undergoes two hydroxylations in the body for activation. Calcitriol (1,25-dihydroxyvitamin D3), the active form of vitamin D, has a half-life of about 15 h, while calcidiol (25-hydroxyvitamin D3) has a half-life of about 15 days.
The most common electrolytes that can cause palpitations when they get low are potassium and magnesium.
Some researchers have suggested that vitamin D deficiency (VDD) could be associated with such symptoms as chest pain, anxiety, and fatigue (Ahmed, 2016; Roy et al., 2014; Sagarad et al., 2016).
Magnesium plays a big role in keeping your heart pumping at a regular pace. Deficiencies are common and can lead to palpitations. But getting more magnesium in your diet is easy.
Most people don't experience side effects with vitamin D, unless too much is taken. Some side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others.
If you are taking a supplement for a true deficiency, such as a low iron, B12, folic acid or vitamin D, then you should consult your doctor before making any changes. But Dr Fenton added: “If however, you have been taking general vitamin supplements, it is absolutely fine to just stop.
various studies have shown that a higher vitamin D dose administered weekly could result in some positive health outcomes for certain groups. A 2023 meta-analysis, for example, found that very high weekly dosages (up to 21,000 IU) reduced intensive care unit hospitalization and death in people with COVID-19.
When to take vitamin D. It just plain doesn't matter, as long as you take it with food, says Dr. Manson. Her advice: Take it when you'll remember to take it — morning, noon or night — and take it with a meal, she says.
tl;dr. There's no set time of day that's best to take vitamin D supplements. Some people say taking vitamin D supplements at night is an insomnia risk. There's no research to confirm this, but you might want to take your supplement earlier in the day if you think it's screwing with your sleep.
Too much vitamin D can cause harmful high calcium levels. Tell your doctor right away if any of these signs of high vitamin D/calcium levels occur: nausea/vomiting, constipation, loss of appetite, increased thirst, increased urination, mental/mood changes, unusual tiredness.
Most people get them because of anxiety. Other causes include: pregnancy, caffeine, alcohol or spicy food. Heart palpitations are common and usually aren't dangerous.
Stress, exercise, medication or, rarely, a medical condition can trigger them. Although heart palpitations can be worrisome, they're usually harmless.
If you're experiencing what feels like frequent or prolonged episodes of palpitations, or you're also having symptoms such as chest pain or dizziness when you have these episodes, it's a good idea to talk to your GP.
