Understanding Vitamin E and Heart Palpitations
Heart palpitations can be a scary experience. You suddenly become aware of your heartbeat pounding hard or fluttering in your chest. For some people, palpitations are occasional and harmless. But they can also signal underlying heart issues. If you experience regular heart palpitations, you may wonder if vitamins or supplements can help calm your heart rhythm.
What Causes Heart Palpitations?
Palpitations are caused by alterations in your heart's electrical system that controls the heartbeat. Certain triggers can throw off your hearts normal sinus rhythm. These include:
- Stress and anxiety
- Vigorous exercise
- Caffeine, alcohol, nicotine
- Dehydration and electrolyte imbalances
- Illnesses and fevers
- Some medications and supplements
In most cases, the heart resets itself and palpitations subside once the trigger goes away. But ongoing palpitations can stem from heart conditions requiring medical care such as:
- Abnormal heart rhythms (arrhythmias)
- Heart valve disorders
- Thyroid problems
- Sleep apnea
Vitamin E and Heart Health
Vitamin E functions as an antioxidant that protects cells from damage. Some research suggests vitamin E can support cardiovascular health. But other studies found no benefits. And high vitamin E intake was linked to negative effects in some people.
Potential Benefits
Here are some proposed ways vitamin E may help the heart:
- Prevents LDL cholesterol oxidation implicated in clogged arteries
- Reduces inflammation involved in plaque buildup
- Relaxes blood vessels, lowering blood pressure
However, population studies found no positive associations between vitamin E intake levels and heart attack or stroke risk. And a 2005 meta-analysis reported vitamin E increased mortality.
Drawbacks and Dangers
There are some important downsides to consider regarding vitamin E supplementation:
- Increases bleeding risk, especially at high doses
- Interacts with blood thinners and other medications
- Linked to higher prostate cancer risk in men
Due to these factors, most experts advise obtaining vitamin E from food rather than supplements. Adults need only 15 mg daily, easily achieved by eating nuts, seeds, vegetable oils, green leafy vegetables, and fortified cereals.
Can Vitamin E Cause Palpitations?
Evidence directly linking vitamin E supplements to heart rhythm issues is limited. But some concerns exist due to vitamin Es anticoagulant effects. By making your blood less likely to clot, high vitamin E intake could theoretically impact heart functioning.
One study investigated this by giving healthy adults either 1200 IU of alpha-tocopherol vitamin E or a placebo daily for six weeks. Participants then wore heart monitors for 48 hours. Results showed no significant differences in heart rhythm disturbances between the two groups. A few case studies described patients experiencing palpitations and atrial fibrillation after taking high-dose vitamin E. But causation was not definitively established.
Potential Mechanisms
A few theories may explain how vitamin E supplementation might trigger heart rhythm problems in sensitive individuals:
- Thins blood and interferes with optimal blood viscosity and flow
- Causes electrolyte imbalances like low potassium or magnesium
- Interacts with heart medications slowing electrical conduction
Other Supplements for Heart Palpitations
Due to spotty evidence supporting vitamin E for heart health, you may wonder what other vitamins, minerals, herbs, and supplements may help stop palpitations instead. Here are a few options to consider:
Magnesium
Magnesium assists in muscle, nerve, and heart electrical functioning. Low magnesium often causes palpitations, and deficiency is common. Adding a magnesium supplement or increasing magnesium-rich foods like nuts, legumes, leafy greens, whole grains, and seeds may calm heart flutters.
Potassium
This mineral is vital for muscle contractions, nerve signals, hydration, and pH balance. Diuretics, sweat, vomiting, diarrhea, and poor nutrition deplete potassium reserves. When low, heart arrhythmias can occur. Potassium-rich foods like potatoes, bananas, dairy, fish, and meat can help stabilize heart rhythms.
Omega-3s
Found abundantly in fatty fish and some plant foods like walnuts and flaxseed, omega-3 fats benefit cardiovascular health in many ways. Research indicates omega-3s help prevent arrhythmias and lower blood pressure and triglycerides. For palpitations, omega-3s may dampen underlying inflammation or alter cell membranes to reduce skipped heartbeats.
Coenzyme Q10
CoQ10 assists mitochondria in producing energy needed for cell growth and maintenance. Since the heart requires vast energy reserves, CoQ10 deficiencies often manifest as heart failure and rhythm disturbances. Small studies report CoQ10 supplements can decrease palpitations and chest pain in certain cases.
Hawthorn
For centuries, herbalists employed extracts from this flowering shrub to treat heart issues. As a rich source of bioflavonoids and antioxidants, hawthorn likely benefits cardiovascular health through multiple mechanisms. Some evidence suggests it can lower high blood pressure and cholesterol while also displaying anti-inflammatory and anti-arrhythmic properties to possibly reduce palpitations.
When to See Your Doctor
Dietary and lifestyle tweaks like getting adequate magnesium, potassium, omega-3s, CoQ10, vitamin D, B vitamins, and antioxidants may help resolve heart flutters. Herbal remedies like hawthorn may also calm palpitations in some individuals.
But if palpitations persist, worsen, or occur with lightheadedness, fainting, or chest pain, seek prompt medical care. These red flag symptoms could indicate a serious heart condition requiring treatment. Vital testing like EKGs, troponin tests, event monitors, echocardiograms, stress tests, or cardiac CT scans help diagnose the underlying cause so proper care can begin.
Your doctor will also review all medications and supplements for potential interactions. Large vitamin E doses may negatively impact heart therapies like blood thinners, rhythm regulating drugs, blood pressure medications, and diuretics.
Once any concerning heart issues get ruled out, supplements and nutrition changes may assist in managing recurring palpitations alongside any medical treatment prescribed by your doctor.
