What is L-Arginine?
L-arginine is an amino acid that helps the body build protein. Your body usually makes all the L-arginine it needs.
L-arginine is also found in most protein-rich foods, including fish, red meat, poultry, soy, whole grains, beans and dairy products.
As a supplement, L-arginine can be used orally and topically.
L-Arginine Dosage:
3-6 grams L-arginine is considered a safe dose. Majority of side effects from L-arginine have been reported at doses exceeding 9 grams - when taken as part of daily dose regime of >30d per day L-arginine. Highest L-arginine dose recorded was 42g/day for 6 weeks in patients suffering from cystic fibrosis, with no adverse effects reported. Table 2 describes some L-arginine doses relative to individual studies.
L-Arginine Benefits:
L-ARGININE AND WEIGHT LOSS
Supplementing animals with L-arginine over a 60-day period showed a decrease in in body fat growth in growing pigs. Authors of these results reported the novelty in using L-arginine in treating obesity in humans. Another study documented L-arginine's effect on a diet-induced obesity rat model.
L-ARGININE AND BLOOD PRESSURE
An L-arginine enriched diet, using both natural foods or pharmacologic preparation, was administered to six healthy individuals, and results showed that L-arginine was able to decrease blood pressure in the subjects.
L-arginine in its effect on insulin sensitivity in obese individuals showed a lowering of systolic and diastolic blood pressure after administration of 8.3g/day of L-arginine over 21 days.
ERECTILE DYSFUNCTION
A double-blind placebo-controlled study assessing a high-dose (5g/day) L-arginine on men with erectile dysfunction showed significant subjective improvements in sexual function. Another similar study, using a randomised clinical trial setting, was conducted evaluating efficacy and safety of 6g L-arginine glutamate for treatment of erectile dysfunction (ED).
L-ARGININE AND PREGNANCY
In a study seeking to determine the effects of an L-arginine supplementation, 228 women were administered L-arginine and results were positive in showing that L-arginine reduced incidences of pre-eclampsia in a high-risk population.
L-ARGININE BODY BUILDING AND EXERCISE
In one study, L-arginine along with creatine improved the number of repetitions performed on a bench press exercise. In 8 healthy patients, L-arginine significantly decreased exercise-induced peak plasma ammonia and lactate.
L-ARGININE AND SLEEP
One interesting study looked at overnight plasma NO levels in sleep apnoea patients and how treatment with nasal continuous positive airway pressure (nCPAP) affected the day after L-arginine levels. After treatment, all patients were recorded as having significant increases of L-arginine. Remarkably, results suggested the importance of Nitric oxide (NO) in sleep apnoea.
