Arginine: Heart Benefits and Side Effects
There are plenty of powerful new drugs to help prevent and treat chronic health problems. But we also know that certain nutrients may help, as well. Take arginine, for example. Arginine has gotten lots of attention lately for its potential heart benefits. That's important because, today, about 85.6 million Americans have some form of cardiovascular disease.
Deficiencies of arginine are rare. It's abundant in many different types of foods, and your body can also make it. Arginine-rich foods include red meat, fish, poultry, wheat germ, grains, nuts and seeds, and dairy products. But what does arginine do for the heart, and are there potential side effects?
Why Do We Need Arginine?
Arginine, also known as L-arginine, is involved in a number of different functions in the body. They include:
Helping the kidneys remove waste products from the body
Maintaining immune and hormone function
Dilates and relaxes the arteries
As a natural dietary supplement, arginine has garnered particular attention for its possible heart benefits.
What Are Arginine's Heart Benefits?
In the body, the amino acid arginine changes into nitric oxide (NO). Nitric oxide is a powerful neurotransmitter that helps blood vessels relax and also improves circulation.
Some evidence shows that arginine may help improve blood flow in the arteries of the heart. That may improve symptoms of clogged arteries, chest pain or angina, and coronary artery disease. However, there currently is no data on how the long-term use of arginine affects cholesterol or heart health.
Since arginine may help arteries relax and improve blood flow, it may also help with erectile dysfunction.
There are other potential health benefits with arginine, such as possible reduction of blood pressure in some people and improved walking distance in patients with intermittent leg cramping and weakness known as intermittent claudication. However, the scientific studies are not conclusive enough for experts to make any firm recommendations.
Not all studies on arginine have been positive. A 2006 study showed that arginine was not helpful -- and may have been harmful -- for treating heart attacks in combination with standard treatment.
L-arginine is a chemical building block called "an amino acid." It is obtained from the diet and is necessary for the body to make proteins. L-arginine is found in red meat, poultry, fish, and dairy products. It can also be made in a laboratory and used as medicine.
L-arginine is used for heart and blood vessel conditions including congestive heart failure (CHF), chest pain, high blood pressure, and coronary artery disease. L-arginine is also used for recurrent pain in the legs due to blocked arteries (intermittent claudication), decreased mental capacity in the elderly (senile dementia), erectile dysfunction (ED), and male infertility.
Some people use L-arginine for preventing the common cold, improving kidney function after a kidney transplant, high blood pressure during pregnancy (pre-eclampsia), improving athletic performance, boosting the immune system, and preventing inflammation of the digestive tract in premature infants.
L-arginine is used in combination with a number of over-the-counter and prescription medications for various conditions. For example, L-arginine is used along with ibuprofen for migraine headaches; with conventional chemotherapy drugs for treating breast cancer; with other amino acids for treating weight loss in people with AIDS; and with fish oil and other supplements for reducing infections, improving wound healing, and shortening recovery time after surgery.
Some people apply L-arginine to the skin to speed wound healing and for increasing blood flow to cold hands and feet, especially in people with diabetes. It is also used as a cream for sexual problems in both men and women.
How does it work?
L-arginine is converted in the body into a chemical called nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body.
L-arginine is POSSIBLY SAFE for most people when taken appropriately by mouth, administered as a shot, or applied to the skin, short-term. It can cause some side effects such as abdominal pain, bloating, diarrhea, gout, blood abnormalities, allergies, airway inflammation, worsening of asthma, and low blood pressure.
