How do nitric oxide supplements work?
Nitric oxide is a molecule used to deliver messages between cells in the body.
It performs different functions in the body like regulating blood circulation, and helping with regular activities in the vital organs like your stomach, kidneys, liver, brains and lungs (7).
They help in transmitting information in between brain cells, they help the immune system fight off bacteria and defend against tumors and infections, reduce inflammation, improve sleeping patterns, regulate blood pressure, assist in gastric motility, increase sense recognition like sense of smell, and even elevate your levels of endurance and strength (8).
One of its oxides is nitrogen. It is a free radical and physiologically works by relaxing the vascular smooth muscles and binds to the heme moiety of the cytosolic guanylate cyclase where it eventually leads to vasodilation. It can be used as a supplement or a simple inhaling gas, depending on the structure of the compound (9).
Many NO supplements contain the amino acid arginine, or the arginine alpha-ketoglutarate. It boosts the nitric oxide levels and in turn helps increase muscle growth, improving strength and muscle performance.
Research indicates that increasing levels of nitric oxide in the body along with of the arginine supplements increases blood vessels and improves blood flow, and even improves the endothelial lining of blood vessels. This mechanism has also shown to improve exercise performance in many patients with cardiovascular problems.
The list of nitric oxide benefits goes on and on, from increasing muscle nutrient delivery to increasing the rate of protein synthesis (10). This is why many supplement stores have a hard time keeping the best brands of nitric oxide supplements in-stock.
Athletes and bodybuilders like taking NO supplements with L-arginine and L-citrulline to help facilitate the blood and oxygen flow into the skeletal muscles.
The combination of these also helps in the removal of exercise-induced lactic acid, which is a major factor in fatigue and recovery time. Nitric oxide supplements reduce this buildup and dramatically decrease recovery times after your workout (11).
What are the side effects of nitric oxide?
Nitric oxide supplements rarely have side effects in the body, although they rarely can affect the heart, cause erectile dysfunction and even tamper with muscle building.
For heart disease, NO actually offers a lot of benefits. The interior surface or the endothelium of the arteries produce nitric oxide. Over time, plaque can buildup in the arteries.
When this occurs it reduces the body’s capability to produce nitric oxide. NO supplements can help increase this production, so there’s no real surprise they are becoming more popular than ever.
For men with erectile dysfunction, most NO supplements boost the nitric oxide pathway in the body to cascade the enzyme reactions to help produce more blood flow into the male genital organ causing better erections (12). No one likes to talk about it, but if you’re experiencing ED, you might want to give a NO supplement a try (or try a natural test booster).
When it comes to Nitric Oxide supplements for body builders, many use it to help intensify their workout routines.
It wont pump up the muscles, meaning it does not add or produce nitric oxide which is a gas, but most supplements have L-arginine and can increase the nitric oxide levels in the body. This will then increase the blood flow to the muscles and other organs.
Clinical studies have been conducted and have showed that with these supplements over time, there is no real significant increase in muscle size and fullness, however they have increased the intensity of exercise and endurance among elderly people and athletes.
NO supplements have also been found to be helpful to people with cardiovascular problems like atherosclerosis and angina pectoris (13).
