    Can supplements clean arteries? Plaque treatment is not a cleanse

    No retail supplement should be promised to clean plaque from arteries. Atherosclerosis care focuses on cardiovascular risk, medicines and procedures when appropriate; a small cholesterol change is not proof that a product removes plaque.

    Plaque is part of an arterial disease process

    NHLBI describes plaque as a mixture including fat, cholesterol, calcium and other substances that can narrow arteries and contribute to clot-related complications. It is not simply material that a drink or capsule flushes away. [1]

    Established treatment has several targets

    Heart-healthy eating, activity and risk-factor management are foundations. Cholesterol-lowering medicines and other treatments may be prescribed according to risk and disease, while procedures can be needed for significant obstruction. Follow the individualized plan rather than a universal cleanse. [1]

    A lower cholesterol result is not a plaque-removal demonstration

    NCCIH describes small cholesterol effects for some products such as garlic or soy. The size of a laboratory change and the evidence for cardiovascular outcomes are separate questions. It does not follow that a supplement opens a narrowed artery. [2]

    Antioxidant language does not establish prevention

    NCCIH notes that evidence does not support antioxidant supplements for preventing cardiovascular disease. Vitamin E and beta-carotene are not recommended for that purpose. A biological explanation about oxidation cannot replace clinical outcomes. [3]

    Ask which outcome the claim measures

    Imagine an advertisement says a capsule cleans arteries because cholesterol fell. Ask whether plaque or cardiovascular events were actually evaluated and whether the exact formula was studied. Do not stop prescribed prevention treatment based on that claim. [1][4]
