Dr. Suzanne Steinbaum’s Top 7 Supplements for Heart Health & Longevity

As a cardiologist who has spent her career championing preventative health, I believe the most powerful medicine we have is the ability to nourish our bodies before the trouble sets in. While a healthy lifestyle, exercise, stress reduction, and meaningful relationships are critical pillars of well-being, the truth is that even with the best intentions, many of us still fall short in key nutrients—nutrients that are foundational to heart health, cardiovascular function, longevity, and vibrant living. That's why targeted supplementation isn't just an option; for many, it's a necessary adjunct to medical care. I've spent years evaluating the clinical research, reading between the lines of misleading labels, and identifying the supplements that truly deliver what our bodies need. In The Heart Book, I call out these supplements, and I also share the favorites I fully support and recommend. 1. Magnesium: The Unsung Hero of Heart & Muscle Health Magnesium is involved in over 600 biochemical processes in the body, yet it's one of the most common deficiencies I see. From supporting healthy blood pressure and heart rhythm to promoting muscle relaxation and better sleep, magnesium is essential, especially for women, athletes, and anyone dealing with ongoing stress. Not all forms are created equal, so I look for well-absorbed options like magnesium glycinate or malate that are formulated to be fully reacted. What does that mean? Essentially magnesium needs to be in a true chelated form for optimal absorption and bioavailability, stay away from the inferior and inexpensive forms such as oxide, or carbonate. 2. Fiber: The Right Everyday Fiber for GI, Blood Sugar and Cholesterol support Dietary fiber doesn't get the glamour it deserves, but it plays a leading role in maintaining healthy cholesterol, improving digestion, and stabilizing blood sugar. A quality soluble fiber supplement can help bridge the gap when our diets fall short—something I see all too often in even the most health-conscious patients. Today more than ever consumers are looking for ways to help support their heart by balancing their blood sugar, Fiber plays a key role in helping to balance blood sugar response and insulin, and for all those who are experimenting with GLP1 solutions you're fiber intake is critical for overall gut and digestive health. 3. Omega-3 Fish Oil: Nature's Foundational Heart Supplement Imbalanced Inflammation is at the root of nearly every health condition, and omega-3s are one of the best ways to combat it. These essential fatty acids, especially EPA and DHA, support brain function, reduce triglycerides, and help maintain overall heart function. I only recommend omega-3s that are sustainably sourced, third-party tested, and free of heavy metals. 4. Vitamin D: The Sunshine Vitamin That Does So Much More Vitamin D is vital for immune health, mood regulation, and calcium absorption. But what many people don't realize is how critical it is for cardiovascular health, particularly for supporting the integrity of our vascular system. Because most of us simply don't get enough from sun exposure or diet, supplementation is often essential. 5. Coenzyme Q10: Fuel for Your Cells As we age—or if you're taking statins—your body's natural levels of CoQ10 decline. This antioxidant is key for cellular energy production, especially in the heart, which has the highest energy demands in the body. I consider it one of the most important supplements for supporting vitality and stamina at any age. Statins have been shown to deplete this essential antioxidant, so supplementing with it daily is critical. 6. A Premium Multi-Vitamin with high absorption chelated minerals, natural forms of Vitamin D&E, and methylated B12 and Folic Acid Your energy, mood, and detox pathways depend on B vitamins. But not all forms are equally bioavailable. I always recommend a multivitamin that includes high quality chelated minerals, natural source Vitamin D & E and methylated folate and B12—these active forms are better absorbed and utilized, especially by those with common MTHFR gene variants, which affect how we process folic acid. This small detail makes a big difference. 7. Bergamore™ Italian Citrus Bergamot: The Clinically Studied Heart Hero If I had to choose a single supplement that truly reflects the future of heart and metabolic health, it would be Bergamore™ Citrus Bergamot. This isn't just another extract on the shelf—this is the most clinically studied, award-winning, and authentic form of Citrus Bergamot available today. What makes it exceptional? It's the NAOMI brand of citrus bergamot, sourced exclusively from Reggio Calabria, Italy—the birthplace of true citrus bergamot. It is the ONLY bergamot in the world to be officially recognized by the Accademia del Bergamotto, a distinction that certifies its authenticity, quality, and origin. That kind of recognition isn't just symbolic—it's a testament to the rigorous standards and purity behind every batch. Clinically, this bergamot has been shown to support healthy cholesterol & triglycerides, promote balanced blood sugar, reduce oxidative stress, and improve metabolic function—all without the side effects commonly seen in alternatives. Its patented unique polyphenol profile is what makes it distinct and so effective, studies performed demonstrate significant improvements in just 30 days. When combined with a strong nutritional foundation and a heart-focused lifestyle, Bergamore™ becomes more than a supplement—it becomes a cornerstone for lifelong cardiovascular wellness.
