This section covers heart and circulation topics. It is split into Blood Pressure, Cholesterol and Heart, and Circulation and Swollen Legs, with reviews, best-of guides and plain explainers in each.Heart supplements often use omega-3, CoQ10, garlic, beetroot, plant sterols and magnesium. We check the dose of each ingredient, the strength of the human evidence, known side effects and interactions, and the refund policy.Heart conditions need medical care. Talk to your doctor before using any supplement if you take blood thinners, blood pressure or cholesterol medication, or are pregnant.Should you talk to a doctor before taking a heart supplement?Yes. Many heart supplements can interact with blood thinners, statins, and blood pressure medicines. Fish oil, garlic, and ginkgo, for example, may raise bleeding risk in some people. A supplement should never replace a prescribed heart medicine. Bring the bottle to your next visit so your doctor or pharmacist can check the ingredients against what you already take.Source: Using Dietary Supplements Wisely, NCCIH
To lower LDL, cut saturated fat and eat more soluble fiber, nuts, soy foods and plant sterols, ideally together. Across 7 trials this portfolio approach lowered LDL by about 17%. Losing 3% to 5% of body weight, staying active and sleeping 7 to 9 hours help further. Supplements add little, and adults with LDL of 160 mg/dL or higher should ask about a statin.
CoQ10 is a compound your body makes for energy. Its best evidence is one 420-person heart failure trial, where 300 mg a day added to usual care cut major heart events from 26% to 15%. Research on statin muscle pain and blood pressure is weak or mixed. It is well tolerated, but it may interact with warfarin and insulin.
Pay for doses, not for adjectives.
