6 science-backed supplements to boost heart health: US cardiologist reveals foods that can slash disease risk

Maintaining a healthy heart goes beyond exercise and diet. US-based cardiologist Dr Dmitry Yaranov, popularly known on Instagram as @heart_transplant_doctor, recently shared six supplements he routinely prescribes to patients to support cardiovascular health. His advice, reported via his Instagram post, combines scientific research with practical guidance for daily wellness.

Why Supplements Matter for Your Heart
Dr Yaranov emphasizes that while medications are crucial for managing heart conditions, certain supplements can provide additional benefits. “These are the only supplements I recommend for my patients,” he wrote in his post. His guidance aims to reduce risks such as high blood pressure, abnormal heart rhythms, and elevated cholesterol levels.

The Six Supplements Recommended
Omega-3 Fatty Acids (Fish Oil)
Found in fatty fish like salmon or through fish oil capsules, omega-3s have been shown to lower triglycerides, reduce blood pressure, and decrease arrhythmia risks.

Coenzyme Q10 (CoQ10)
Known for supporting cellular energy, CoQ10 may improve heart function and reduce blood pressure, especially in patients with heart failure.

Magnesium
Essential for regulating heart rhythm and blood pressure, magnesium deficiency can contribute to arrhythmias and hypertension.

Fiber (Psyllium, Oat Bran)
Soluble fiber helps lower LDL or “bad” cholesterol, directly reducing the risk of heart disease.

Potassium
Critical for balancing sodium levels, potassium helps regulate blood pressure. Cardiologists often monitor levels carefully, with 4-5 mEq/L considered ideal.

Vitamin D
Low vitamin D levels have been linked to an increased risk of heart disease. Supplementation may improve heart health for those with deficiencies.

Consult Your Doctor Before Starting
Dr Yaranov stresses that while these supplements have strong scientific backing, individuals should consult healthcare providers before beginning any new regimen. “Always ensure that supplements are safe for you, especially if you are on medications,” he advises.
