L-arginine is a chemical building block called "an essential amino acid”. Essential amino acids are those that body cannot manufacture it on its own and needs to be consumed through one’s diet. It’s found in red meat, poultry, fish, and dairy products. It can also be made in a laboratory and used as medicine. 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 and stimulates the release of growth hormone, insulin, and other substances in the body. As the aging process occurs, the body’s ability to absorb and convert L-arginine into nitric oxide decreases over time. Therefore, supplementation may be necessary.
L-arginine is primarily used for sustaining a healthy heart, blood vessel, and mental capacity. Some common symptoms associated with decreased L-arginine levels include: erectile dysfunction, male infertility, decreased mental capacity (i.e. brain fog), leg pain due to poor circulation, and early onset dementia.
Some people use L-arginine to improve exercise performance, boost the immune system, and prevent inflammation.
L-arginine is also commonly used with a number of over-the-counter and prescription medications like ibuprofen to help treat migraine headaches.
Regardless if you are young or old L-Arginine can be consumed safely in capsule form. If you are just looking for improved workouts or you suffer from various conditions listed above, L-Arginine supplementation maybe the for you.
