L-arginine is an amino acid, a chemical building block necessary for the body to make proteins. These proteins help your body repair new cells, damaged tissues, and digest food.
Research has confirmed arginine supplements may prove beneficial for certain age groups and health conditions. A meta-analysis found arginine to have significant positive benefits for reducing systolic and diastolic blood pressure in hypertensive adults.
Another study found that L-arginine in watermelon extract helped improve aortic blood pressure. However, more research is needed in the area to understand if these outcomes are the same for all age groups.
Sources of L-Arginine: It is found in red meat, nuts, poultry, fish, and dairy products. Legumes, whole grains, dairy products and fish are other great sources of the compound. However, these are not the only sources of quercetin.
Why Must You Include L-Arginine Supplements In Your Diet?
Our body needs L-arginine to produce nitric oxide (NO) essential for regulating blood pressure. It can also help reduce infection rates in people with compromised immune function.
Erectile Dysfunction (ED): A 1999 study, observed the effects of six weeks of high-dose (5 grams/day) orally administered nitric oxide (NO) donor L-arginine on men with organic ED. It found that men who took 5 grams of L-arginine per day experienced significant improvements in sexual function.
Enhances Athletic Performance: In 2021, a meta-analysis of several studies found that L-arginine may also increase maximal oxygen consumption during exercise and work as an exercise performance enhancer.
Beneficial in pregnancy: According to some studies, L-arginine may be effective in treating preeclampsia, a condition that can cause high blood pressure and protein in the urine.
"Parental oral l-arginine in these women may be at least moderately recommended to improve birth outcomes, resulting in reduced rates of mortality and morbidity between neonatal and adult periods," reads an excerpt from a study published in Nature journal.
Prevents infection: It reduces the relative rate of acquiring a hospital-based infection by 40 percent in hospital patients.
Anti-diabetic: Another study conducted on middle-aged individuals found that taking L-arginine supplements for 18 months reduced the risk of diabetes. While another study claimed that higher intakes of L-arginine may in fact increase the risk. Therefore, it is essential that the supplement be taken in an appropriate dosage.
Side effects: It is usually considered safe to use; however, like all supplements, it may have some side effects such as nausea, vomiting, bloating, diarrhea, and dizziness.
In addition to the aforementioned side effects, L-arginine may interact with diabetes, blood pressure medication, and anticoagulant or antiplatelet medications. Some people may be allergic to such supplements. Therefore, it is extremely important to consult a healthcare provider before including arginine in your diet.
L-Arginine Dosage: The dosage depends on your age, health status and weight. Some studies do claim that doses of up to 30 grams daily can be included in the diet.
