Nitrates are a compound found in vegetables such as dark green leafy veggies like beet greens, kale, spinach, and parsley. It is known as “endothelium-derived relaxing factor” (EDRF) and is made in the body by the amino acid L-arginine, oxygen and NADPH (a type of helper molecule called a co-enzyme). Nitrates are converted into nitrites in the body and then into Nitric Oxide (NO) and provide many health benefits, let's explore.
Top Health Benefits of Nitric Oxide
Nitric Oxide provides quite a few benefits for men and women, including its ability to act as a natural vasodilator whichcan help with cardiovascular health for men and women and sexual health in men.
Nitric Oxide is used to help dilate blood vessels and is mainly used to balance high blood pressure and erectile dysfunction from poor blood supply. It may also have positive effects on people suffering from angina (poor blood supply to the heart), poor circulation, age-related dementia, and Raynaud’s syndrome.
For decades the drugs Nitroglycerine and Amyl Nitrite were used in medicine to help dilate heart blood vessels. Later itwas discovered these drugs were both precursors to Nitric Oxide which is made in your body. It is believed that this is the mechanism of action which allows these drugs to be potent vasodilators.
Humans with atherosclerosis, diabetes, and hypertension often show impaired NO pathways and are depleted in NO.
Understanding How NO Works
All arteries are made up of a kind of muscle tissue called smooth muscle. This allows the arteries to constrict and dilate depending on your body’s needs for more or less blood flow. There are numerous types of high blood pressure but the main type is due to arteries that are too constricted. One way to address certain kinds of high blood pressure is to relax the blood vessels. NO achieves this when it is released by the endothelial layer (inner lining) of our blood vessels. It acts to signal to the surrounding smooth muscle layer of the blood vessel to relax. This, in turn, dilates or widens the blood vessels.
Magnesium is another way this can be achieved. Magnesium and Nitric Oxide work as a great combined therapy for high blood pressure.
Further, Nitric Oxide reduces platelet aggregation into the endothelium (stroke, heart attacks), reduces blood vessel inflammation, supports endothelial tissue inside blood vessels, and increases blood vessel elasticity which is important to support varying degrees of blood volume and blood pressure.
NO also reduces LDL oxidation (the oxidation of the negative type of cholesterol in our body). NO inhibits smooth muscle proliferation. NO prevents white blood cell adhesion and infiltration into the lining of the blood vessels. All of these actions protect your blood vessels and heart.
Tips For Selecting Quality NO Supplements
You can not buy nitric oxide as a supplement but you can buy it in precursor forms. Potassium Nitrate is converted into Nitric oxide in your body. A standard dose is 250 mg daily and is found in cardiovascular formulations with herbs and antioxidants.
Another way your body can make Nitric Oxide is from two amino acids called Citrulline and L Arginine. These amino acids are generally found in powdered forms alone or combination with other amino acids for heart and muscle function.




The layout of this article is simple and easy to digest; I really like it!! Specifically, the headers (eg What is it? What is it used for? Ho does it work? and How to use it?) are both intuitive and pratical. Also, in addition to great layout and clear communication of the information, I would like to add that the content as geat too. And, I didn't know that magnesium could also dilate blood vessels so I will definitely be mentioning this to my father and Uncle, who were both aware of nitric oxide for high blood pressure (but who I don't think know about magenium)-thank you!
Hello Rachel,
Thank you for your comment. We are glad you not only enjoyed the information in our Nitric Oxide article, but the layout and flow. You can also further your knowledge on magnesium with our other articles: https://www.nationalnutrition.ca/articles/supplements/magnesium/
Stay healthy & well
