Arginine is an essential amino acid found in many different types of foods. First isolated in the latter part of the 19th century, the most common form of arginine in use today is l arginine, which is available in many health food stores as a dietary supplement. It is also possible to find amino acids of this type in a number of meats, seafood, and vegetables.

The human body is normally able to manufacture amounts of arginine that are sufficient to meet most of the body’s needs. The remainder is supplied through consumption of various meats and vegetables. However, there are a number of health issues that can impair this ability. When this happens, the individual can compensate by consuming foods that contain appreciable amounts of arginine. If necessary, taking a supplement can augment the arginine that is ingested from a balanced diet.

There are many sources of arginine that can be incorporated into just about any diet. Daily products contain appreciable amounts of this natural amino acid, making the use of cottage cheese and yogurt ideal sources for anyone who is counting calories. Chicken provides a decent source of arginine, as does beef and pork. Several different types of seafood are also excellent sources, including lobster, tuna and salmon.

Arginine is not limited to meats and seafood. There are a number of nuts and grains that can be used to increase arginine levels. Snacks such as peanuts, Brazil nuts, almonds and walnuts are excellent sources. Sunflower seeds, along with pumpkin seeds and sesame seeds are also nutritional snacks that contain arginine. Oatmeal is a great way to ingest arginine, making it an ideal source for people who are trying to limit carbohydrate consumption.

The health benefits of natural amino acids like arginine are varied. Maintenance of an equitable level of the amino acid can help to lower blood pressure and increase the body’s sensitivity to insulin. Arginine is also essential for a healthy immune system, and can aid in expediting the healing process. For men, arginine helps to maintain sperm motility and production and thus minimize the chances for infertility. For both men and women, arginine can help enhance circulation throughout the body, including maintaining a healthy blood flow to the reproductive organs.

Since the body can often produce a good share of arginine on its own, eating a balanced diet is usually all that is required to ingest enough additional arginine to maintain good health. However, additional arginine can aid in overcoming several health issues. Consult a health professional before taking massive amounts of arginine supplements, as there is some potential for interaction with prescription medication.
