Cardiologist Dr. Tiffany DiPietro has shared her top three supplements for your heart, while cautioning against unnecessary supplements. She highlighted Psyllium husk, a fiber supplement most commonly used for helping with constipation, and CoQ10, a vitamin-like antioxidant that helps cells produce energy, protects them from damage and supports the growth of new ones. These supplements can also lower LDL cholesterol, which can raise the risk of serious health problems like heart disease, heart attack and stroke. However, she advised against routine supplements without a reason, especially for those with cardiovascular disease, arrhythmias, uncontrolled blood pressure, heart failure or on anticoagulants. DiPetro also highlighted the potential dangers of certain herbal supplements, including ginkgoins, garlic extract, and high-dose garlic extract.
