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.
