Changes in many genes, each with a small effect, may underlie susceptibility to many common diseases, including cancer, obesity, diabetes, heart disease, and mental illness. In people with a genetic predisposition, the risk of disease can depend on multiple factors in addition to an identified genetic change.
Print. Arginine is an amino acid (a building block of protein), produced in the body and found in many foodsâespecially those rich in protein, such as dairy products, meats, fish, nuts and soybeans.Most of the time, we produce or consume all the arginine we need. Some preliminary studies have found that arginine supplements can improve the function of blood vessels, enhance coronary blood flow, lower blood pressure and even reduce angina and other symptoms in people with heart and/or vascular disease.
One of arginineâs key functions in the body is to convert into nitric oxide. Nitric oxide helps blood vessels relax and expand, which is important for regulating blood flow. Because of this function, doctors often recommend arginine supplements to help treat heart and blood vessel conditions.almon is an excellent source of arginine. Try it baked with asparagus and feta cheese, or cooked with spices and spinach. Pork is another great source; use a slow cooker to get your arginine fix with tender carnitas tostadas. Arginine supplements can come in the form of oral tablets or injections.
