“6 vitamins to unclog your arteries” — what the evidence says
This is a common health headline, but vitamins cannot literally “unclog” an artery once an atherosclerotic plaque has formed. There is also no vitamin regimen proven to safely dissolve established arterial plaque.
Some nutrients are important for cardiovascular health, but that’s different from removing plaque.
The six nutrients commonly mentioned
Vitamin B3 (niacin)
Niacin can lower LDL cholesterol and triglycerides and raise HDL. However, despite these effects on cholesterol, adding niacin to modern cholesterol treatment has not generally been shown to provide additional cardiovascular benefit, and high doses can cause significant side effects. It should not be taken in high doses without medical supervision.
Vitamin D
Vitamin D is important for bone and overall health. Although low vitamin-D levels are associated with cardiovascular risk, supplementation has not been shown to unclog arteries or reliably prevent heart attacks in people who aren’t deficient.
Vitamin B12
B12 is needed for normal blood and nerve function. Correcting a B12 deficiency is important, but taking extra B12 doesn’t remove arterial plaque.
Folate (vitamin B9)
Folate helps metabolize homocysteine. Supplements can lower homocysteine levels, but that doesn’t mean they reverse atherosclerosis or prevent cardiovascular disease in everyone.
Vitamin C
Vitamin C is an antioxidant and is essential for normal connective-tissue function. Eating vitamin-C-rich fruits and vegetables is beneficial, but vitamin C supplements aren’t an established treatment for blocked arteries.
Vitamin E
Vitamin E has antioxidant properties, but large clinical studies haven’t shown vitamin-E supplements to be an effective way to prevent cardiovascular disease or remove plaque.
What actually helps prevent or slow artery blockage?
The strongest evidence supports controlling LDL cholesterol, blood pressure and diabetes; avoiding tobacco; exercising regularly; maintaining a healthy weight; and eating a heart-healthy diet. For people at sufficiently high cardiovascular risk, medications such as statins can substantially reduce the risk of heart attack and stroke.
If an artery is already significantly narrowed, treatment depends on the location and severity. In some cases, doctors use medications; in others, procedures such as angioplasty/stenting or bypass surgery may be appropriate.
Bottom line: Don’t treat a headline promising to “unclog arteries with six vitamins” as a substitute for cardiovascular treatment. Vitamins are useful when you have a deficiency or a specific medical indication, but they are not a proven plaque-removal treatment.
