The idea of using vitamins to “unclog” arteries sounds appealing. After all, vitamins are essential nutrients, and many are involved in protecting cells, maintaining blood vessels, and supporting normal metabolism.
But there is an important distinction between supporting cardiovascular health and removing established arterial plaque.
Atherosclerosis occurs when plaque builds up inside arteries. This plaque can contain cholesterol, fats, calcium, and other substances, gradually narrowing arteries and increasing the risk of heart attack, stroke, and peripheral artery disease.
No vitamin has been proven to act like a drain cleaner that simply dissolves artery plaque.
However, certain vitamins are important for normal cardiovascular function, and getting adequate amounts through a balanced diet can be part of an overall heart-healthy lifestyle.
Let’s look at six vitamins that are often discussed in connection with artery health—and what the evidence actually tells us.
1. Vitamin D
Vitamin D is best known for its role in calcium absorption and bone health, but it also participates in many other biological processes.
Low vitamin D levels have been associated in observational research with cardiovascular risk. However, an association does not necessarily mean that taking extra vitamin D will prevent or reverse atherosclerosis.
For people who are deficient, correcting the deficiency is important for overall health. But taking high-dose vitamin D should not be viewed as a treatment for blocked arteries.
Where can you get vitamin D?
Sources include:
- Fatty fish
- Egg yolks
- Fortified foods
- Some mushrooms
- Sunlight exposure, depending on skin type, location, season, and other factors
If you suspect that you are deficient, your healthcare professional can determine whether testing or supplementation is appropriate.
2. Vitamin C
Vitamin C is an antioxidant involved in collagen production, wound healing, immune function, and other biological processes.
Because oxidative stress is involved in cardiovascular disease, vitamin C has attracted considerable interest in heart-health research.
However, that does not mean vitamin C supplements can remove
