Nitric Oxide is necessary for healthy circulation of blood. It helps in dilating blood vessels, preventing blood clots and regulating blood pressure. It also provides help in inhibition of the gathering of hazardous arterial plaque.

The production of NO (nitric oxide) from L-arginine totally depends on the family of enzymes, known as NOS (nitric oxide synthesis). There are basically three types of nitric oxide synthesis enzymes have been found. Those are:

• One is present in the immune system.
• One is present in endothelial cells of veins and arteries.
• One is present in the brain.

The NOS enzymes that are present in the immune system produce NO to help in destroying cancer and bacteria cells.
The NOS enzymes present in the endothelial cells generate NO. And nitric oxide then helps in maintaining different functions of the body.
The NOS enzymes those are present in the central nervous system and brain, helps in maintaining almost every functioning of the brain. It shows that these enzymes are concerned with almost every function of brain. But if they will be improperly regulated then they may have some important health issues. Too much creation of Nitric oxide can also destroy brain cells because it is a hazardous free gas. And too little creation of Nitric oxide may also affect memory.

Nitric Oxide can help in preventing strokes and heart diseases in the given ways:

• By controlling platelet function: Nitric oxide enhances a well-organized vascular network, which sheds platelets and thus inhibits dangerous clots. That’s how, the threat of heart diseases decreased at the greater extent.

• By expanding blood vessels: NO (Nitric oxide) protects human blood vessels by smoothing muscle tissues from harmful conditions. It provides the flexibility that is necessary in blood circulation with very less pressure. And hence reduces the rate of occurrence of heart diseases.

• By lowering total cholesterol level by ten to twenty percent: Nitric oxide helps in lowering cholesterol level through its protective antioxidant activity. Many researches suggest that the consumption of nitric oxide by your body reduces the level of cholesterol by 10% to 20%.

• By reducing dangerous arterial plaque by fifty percent: Nitric oxide acts as a very effective antioxidant, which inhibits the way of monocytes (it is a type of immune system cell) into an artery wall. It reduces inflammation, which promotes arterial plaque. And thus the risk of heart diseases decreases.

It is recommended by many studies that daily intake of various nutritional supplements which increase the production of NO in your blood vessels is really helpful and beneficial.
