L-arginine is a conditionally essential amino acid, meaning it only has to be consumed in the diet under certain conditions, while healthy adults can make all they need Several studies support the use of L-arginine for increasing blood flow, but only in certain populations.
In those with high blood pressure, including pregnant women, L-arginine is effective at lowering blood pressure 25 , 26 , 27 , However, evidence on the ability of L-arginine to improve blood flow or exercise performance in healthy individuals remains mixed 29 , 30 , 31 , L-arginine is generally recognized as safe when taking 20 grams per day, but it may cause digestive symptoms at dosages as low as 10 grams 33 , L-citrulline is a dispensable amino acid, meaning your body can make all it needs.
In fact, L-citrulline increases levels of L-arginine in your body more than supplementing with L-arginine itself does. This is because a large percentage of L-arginine is broken down before reaching your bloodstream Studies have found L-citrulline to increase blood flow, improve exercise performance and lower blood pressure 36 , 37 , 38 , L-citrulline is considered relatively safe, and there is a low risk of side effects, even with high doses The amino acids L-arginine and L-citrulline are used to produce nitric oxide in your body.
They are available as supplements and have beneficial effects on vascular health and blood flow. Mouthwash destroys bacteria in your mouth that can contribute to the growth of cavities and other dental diseases.
Unfortunately, mouthwash kills all types of bacteria, including the beneficial ones that help produce nitric oxide. Special bacteria in the mouth convert nitrate to nitric oxide. In fact, humans cannot produce nitric oxide from nitrate without these bacteria Research has shown that mouthwash kills the oral bacteria needed to produce nitric oxide for up to 12 hours 42 , This leads to a decrease in nitric oxide production and, in some instances, an increase in blood pressure 44 , The detrimental effects of mouthwash on nitric oxide production may even contribute to the development of diabetes, which is characterized by malfunctions in insulin production or action.
Without nitric oxide, insulin cannot work properly. Mouthwash kills many types of bacteria in the mouth, including the ones that help produce nitric oxide. Endothelium refers to the thin layer of cells that line the blood vessels. These cells produce nitric oxide, which keeps blood vessels healthy. Insufficient nitric oxide production results in endothelium dysfunction, which can contribute to atherosclerosis, high blood pressure and other risk factors for heart disease Several studies have shown that regular physical activity increases endothelial vasodilation in people who have high blood pressure and heart disease, as well as in healthy individuals 48 , 49 , Studies have also shown that exercise increases antioxidant activity, which helps inhibit the breakdown of nitric oxide caused by free radicals 51 , As all 3 isoforms of NOS are present either in the epidermal cells, dermal cells or both, skin can produce nitric oxide by an enzyme dependent mechanism.
Human skin can release nitric oxide in an enzyme independent manner by UVA photolysis of nitric oxide stores. Nitric oxide is also produced by reduction of sweat nitrate by skin commensal bacteria, in particular Staphylococci. Nitric oxide does not usually exist in its free form in the body due to its unstable nature but reacts with other molecules to form more stable products.
Nitrate is the main storage form of nitric oxide. It is very stable when compared with other storage forms such as nitrites and RSNOs, which are important carriers and donor molecules of nitric oxide. There are no tests for nitric oxide itself, as it is too unstable. Instead, nitrates, nitrites and nitrosylated compounds may be measured using the following tests. In the skin, insufficient nitric oxide may result in psoriasis by promoting cell proliferation and reducing differentiation of skin cells.
Consuming food rich in nitrates and nitrites increases the level of nitric oxide and its storage form. Just as deficiency of nitric oxide can lead to disease, too much can also cause disease. Nitric oxide is released from the cerebral vasculature, brain tissue and nerve endings. In the skin, ultraviolet irradiation may lead to excessive nitric oxide production by enzyme-dependent and independent mechanisms.
Nitric oxide has a role in the promotion and growth of melanoma via multiple mechanisms. Due to its antimicrobial properties, a nitric oxide-releasing gel formulation , berdazimer sodium SB, SB, Novan , is under evaluation to treat dermatophyte fungal infections such as tinea pedis and viral skin infections including genital warts and molluscum contagiosum.
