6 Vitamins to “Unclog” Your Arteries: What You Should Know
There is an important distinction between supporting artery health and actually removing plaque from blocked arteries. No vitamin has been proven to safely “unclog” atherosclerotic arteries once significant plaque has formed. Vitamins can correct deficiencies and support normal body functions, but they should not replace cholesterol-lowering treatment, blood-pressure control, exercise, or other medical care.
Here are six vitamins commonly discussed in relation to cardiovascular health:
1. Vitamin D
Vitamin D is important for bone health, muscles, and normal immune function. Low vitamin-D levels have been associated with cardiovascular risk in observational studies.
However, taking extra vitamin D has not been shown to remove arterial plaque or prevent heart attacks simply because the vitamin-D level is normal.
Avoid taking very large doses unless medically advised, because excessive vitamin D can raise blood calcium and cause kidney and other problems.
2. Vitamin B12
Vitamin B12 helps maintain healthy red blood cells and the nervous system.
A deficiency can increase homocysteine, an amino acid associated with cardiovascular risk. Treating a genuine B12 deficiency is important, but B12 supplements have not been shown to clear blocked arteries in people who aren’t deficient.
Good food sources include meat, fish, eggs, milk, and fortified foods.
3. Folate (Vitamin B9)
Folate also participates in homocysteine metabolism. Foods rich in folate include:
-
Leafy green vegetables
-
Beans and lentils
-
Asparagus
-
Avocado
-
Fortified grains
Folate supplementation can lower homocysteine, but lowering homocysteine with vitamins does not necessarily translate into fewer cardiovascular events.
4. Vitamin B6
Vitamin B6 works together with B12 and folate in several metabolic processes, including homocysteine metabolism.
A balanced diet usually provides enough B6. Taking high-dose B6 supplements for prolonged periods can actually cause nerve damage, so more is not better.
5. Vitamin C
Vitamin C is an antioxidant and is essential for collagen production and normal blood-vessel function.
Fruits and vegetables are excellent sources, including:
-
Oranges and other citrus fruits
-
Guava
-
Kiwi
-
Bell peppers
-
Tomatoes
-
Broccoli
Eating plenty of vitamin-C-rich produce is part of a heart-healthy diet, but vitamin C supplements cannot dissolve cholesterol plaque from arteries.
6. Vitamin E
Vitamin E has antioxidant properties and is found in foods such as nuts, seeds, vegetable oils, and spinach.
Despite its antioxidant effects, vitamin-E supplements have not been established as a treatment for atherosclerosis or a way to prevent cardiovascular disease. High-dose supplementation can also increase the risk of bleeding in some people.
What Actually Helps Reduce Artery Disease?
If arteries are narrowed because of atherosclerosis, the most important evidence-based measures are controlling the underlying risk factors:
-
Lower LDL cholesterol when appropriate
-
Control high blood pressure
-
Don’t smoke
-
Maintain a healthy weight
-
Exercise regularly
-
Eat plenty of vegetables, fruits, whole grains, legumes, nuts, and other minimally processed foods
-
Manage diabetes if present
-
Take prescribed medications consistently
For someone with established cardiovascular disease or significantly elevated LDL cholesterol, a doctor may recommend statins or other cholesterol-lowering medicines. These treatments have much stronger evidence for reducing cardiovascular events than vitamin supplements.
Bottom Line
The phrase “6 vitamins that unclog your arteries” is misleading. Vitamins can be essential for good health and correcting deficiencies is important, but there is no vitamin supplement that has been proven to physically dissolve established arterial plaque.
If you have a cholesterol or artery problem, the most useful next step is to know your LDL cholesterol, HDL cholesterol, triglycerides, blood pressure, and other cardiovascular risk factors and discuss them with a healthcare professional.
