The research has not shown that nitric oxide supplements can help elite athletes. Researchers carried out these studies on young males, so they do not know how nitric oxide supplements may affect older people and females. Because nitric oxide supplements enhance blood flow, researchers have conducted studies to determine if it could enhance blood flow for people with erectile dysfunction ED. According to an article in the journal Future Science OA , some studies have shown taking nitric oxide may reduce ED in those with mild to moderate ED.
Preeclampsia , which is a form of high blood pressure that can occur in pregnancy, can be dangerous for both the woman and baby. A study in the European Journal of Clinical Investigation found that pregnant women who took L-arginine supplements for a prolonged period had lower blood pressure readings than pregnant women who did not take L-arginine.
Although researchers need to conduct more studies, the results are promising for women struggling with high blood pressure in pregnancy. These are just some examples of more extensive studies that examined the effectiveness of nitric oxide. However, there are no studies that establish how much nitric oxide supplements people should take to achieve the same results as the study participants did.
People take nitric oxide for a variety of reasons, many of which do not have any scientific research to support them. Most of these benefits are anecdotal, meaning that people may have reported a benefit, but there is no proof backed up by a scientific study.
For most people, taking nitric oxide supplements does not cause side effects. When side effects do occur, they are often mild and may include:. However, some people should not take the supplements because of the risk of potential side effects. These include people with:. Doctors also have some concerns that taking nitric oxide supplements could make some conditions worse. These include kidney disease, herpes , and after a person has had a heart attack.
A study published in in JAMA found that people taking L-arginine after a heart attack had a higher chance of death, experiencing a repeat heart attack, and being hospitalized than people who did not.
This article does not give a comprehensive list of potential conditions where a person should not take nitric oxide supplements.
The supplements may also interfere with medications, such as those for diabetes and high blood pressure. Anyone thinking about taking nitric oxide supplements should talk to their doctor first to ensure they will not interfere with existing conditions or any other medications they are taking.
Nitric oxide supplements have been available for decades, but as there is little scientific evidence to back up their use for specific health benefits, doctors do not routinely recommend them. Instead, doctors may prefer to recommend lifestyle modifications or medications that scientists have proven to treat medical conditions effectively. Nitric oxide supplements do not cause many side effects in most people, so some people might choose to try them.
However, individuals should make sure that they do not have specific medical conditions that nitric oxide could harm. Nitric oxide supplements don't actually contain nitric oxide. Instead, they contain ingredients or substrates that are thought to give your body a nudge to produce more nitric oxide, such as L-arginine and L-citrulline. While the L-arginine in your body is involved in nitric oxide production, research is mixed as to whether taking it in supplement form will increase nitric oxide production, and if it could, whether that would actually enhance exercise performance and improve health, Jones says.
Nitric oxide is a gas that's made by your body, and one of its primary purposes is to promote vasodilation, or increased blood flow. Because blood is responsible for carrying oxygen to working muscles, the reasoning is that the increased blood flow caused by taking nitric oxide supplements might help you work out for a longer period of time and speed up recovery time.
In the body, "nitric oxide is secreted by the endothelial cells, which line the inner walls of the blood vessels, and it communicates with the smooth muscle cells, triggering them to relax," explains Nathan Jenkins, Ph.
This blood flow regulation plays a role in multiple body functions, including maintaining erections and controlling blood pressure. It may increase blood flow to the penis, which can help a man maintain his erection, adds Rizzo, so for that reason, it could increase performance in bed and help you go longer. Honestly, we don't really know. There's simply not enough evidence to suggest that they do. In studies that have shown a link between improvements in performance and nitrate levels in the blood, such positive results could simply be a result of extensive training, as exercise itself enhances nitric oxide activity.
Plus, dietary nitrate comes from other sources, like vegetables, and most studies don't control for this. Even if there are benefits to nitric oxide supplementation, it's unclear whether they would apply to everyone. A review of 42 studies related to the effects of dietary ingredients linked with nitric oxide and exercise performance found mixed results: the review concluded that while nitric oxide supplements may "improve tolerance" to aerobic and anaerobic exercise in people who either aren't in shape or are moderately trained, there seems to be no benefit in highly trained people.
When taken in relatively low amounts, there aren't any side effects associated with NO supplements. Though the jury's out on whether nitric oxide supplements really do improve performance, Bloomer says if you want to try them at a low dosage, go ahead. That said, if you're prone to hypotension or low blood pressure , you might want to skip them, as they could leave you feeling lightheaded or dizzy. Nitric oxide is in almost all organisms, from bacteria, plant, and animal cells.
The lining of the blood vessels uses nitric oxide to relax smooth muscles, thus increasing blood flow. There are foods that contribute to the end production of nitric oxide. Leafy, green vegetables are number one on the list i. One of the most powerful foods is b eet juice which helps lower blood pressure, which in turn helps your body boost nitric oxide production. Also beneficial are nuts, beans, turkey, seafood, and dairy products as they produce Arginine.
Arginines are found in high protein foods like nuts, beans, turkey, seafoods, and dairy products. Two of the most common are L-arginine and L-citrulline.
They are both amino acids. If supplements say they contain nitric oxide, beware. M any of the problems associated with too many nitrates might be attributed to sodium nitrates commonly used as preservatives and color fixatives in processed foods.
Exercise helps the body produce this much-needed molecule. When you are exercising and run out of oxygen, your muscles hurt, even cramp. If you have a healthy nitric oxide level in your system, its release dilates blood vessels, which in turn allows more oxygen into your tissues.
There are bacteria in your mouth that aid in the major production of nitric oxide, and most mouthwashes destroy it. New results in the destruction of this bacteria are showing a possible contribution to the development of diabetes.
Nitric oxide regulates the production and action of insulin. If your nitric oxide levels are too low, insulin might be ineffective. If you use mouthwash twice or more a day, you could, perhaps, be in a higher percentage for developing diabetes.
