Natural vasodilators: How to dilate blood vessels naturally and increase blood flow

natural vasodilatorsVasodilators are medications used to open up blood vessels and prevent heart-related health conditions, but there are also natural vasodilators that can dilate vessels and increase blood flow.

Vasodilators impact the muscle walls of the arteries and veins. They prevent the muscles from tightening and the wall from narrowing, which then allow blood to flow more freely through vessels. When blood is flowing easily, the heart doesn’t have to work as hard and blood pressure is reduced.


The production of NO—nitric oxide—is important for the regulation of blood flow. Abnormal NO production occurs in different disease situations. It can have a negative impact on blood flow and vascular functions. Nitric oxide is produced from the amino acid L-arginine by action from nitric oxide synthase (NOS). Vascular actions of NO can include preventing sympathetic vasoconstriction, acting as an anti-inflammatory, having an anti-thrombotic effect, and preventing muscle hyperplasia. On the other hand, when NO production is hampered, it can lead to hypertension, thrombosis, vascular hypertrophy and stenosis, or excess inflammation.

Nitric oxide is a strong vasodilator; something you can get from flavonoid and L-arginine rich foods. There are many natural vasodilator foods to choose from. Read on for a comprehensive list of some of the best natural vasodilator food options.

Research suggests that vitamin C protects nitric oxide molecules from free radical damage, making it a good natural vasodilator.

This vitamin is known to raise levels of nitric oxide synthase, which again is the enzyme that converts L-arginine into nitric oxide.


This fruit is capable of boosting nitric oxide, reducing inflammation, and reducing oxidative stress, which are all factors related to coronary artery disease. Polyphenols in pomegranate help convert nitrite into nitric oxide, making it a viable natural vasodilator.


This nut is high in L-arginine, so it can keep blood vessels open. Many other nuts are also good sources of L-arginine. Nutritionists suggest soaking nuts for five to six hours before consuming them.

When it comes to the best natural vasodilator options, it is nice to see that there are a wide variety of foods to choose from. While this should bring some reassurance, especially to those who are not keen on vasodilator medications, any use of foods to control vascular health should be discussed with a doctor. Taking treatment into your own hands can be dangerous. When planned in consultation with a healthcare professional though, foods can make a big difference when it comes to vasodilation.
