Best Supplements for Rapid Heartbeat

By Elise

A rapid heartbeat, also known as tachycardia, can be unsettling and uncomfortable. It may occur due to stress, anxiety, dehydration, nutrient deficiencies, or underlying health conditions such as thyroid imbalances or heart rhythm disorders. Because a fast heart rate can sometimes indicate a serious medical problem, it’s important to seek medical evaluation promptly to determine the cause.

Once urgent conditions have been ruled out, natural supplements may help support heart rhythm stability, reduce stress, and promote overall cardiovascular health. Here are two evidence-based options that may provide gentle, supportive benefits.

Magnesium

Magnesium is an essential mineral involved in hundreds of bodily functions, including regulating heartbeat and muscle contractions. Low magnesium levels can contribute to heart rhythm disturbances, and supplementation may help maintain a steady pulse.

  • Mechanism of action: Supports proper electrical conduction in the heart and helps relax blood vessels and muscles.
  • Dosage or usage tip: Typically taken at 200–400 mg daily, preferably in the citrate or glycinate form for better absorption.

Coenzyme Q10 (CoQ10)

CoQ10 is a powerful antioxidant that supports cellular energy production, especially in the heart muscle. It may help improve heart function, protect against oxidative stress, and support a stable heart rhythm.

  • Mechanism of action: Enhances mitochondrial energy production in heart cells and reduces oxidative damage in cardiovascular tissues.
  • Dosage or usage tip: Commonly taken at 100–200 mg daily with a meal containing healthy fats for optimal absorption.

Summary:

A rapid heartbeat should always be evaluated by a healthcare provider to rule out serious conditions. Once the cause is identified, supplements like Magnesium and CoQ10 may help support healthy heart rhythm, improve cardiovascular function, and reduce stress on the heart.
