GENERAL
DESCRIPTION & APPLICATIONS
|
|
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. http://www.nlm.nih.gov Wikipedia
