What is L-arginine?
L- Arginine is an amino acid found in many foods such as meat, fish, nuts, seeds, legumes and dairy products. It is an essential amino acid, which means that the body cannot produce it itself and must therefore obtain it from food.
L-arginine is an important part of the immune system and is also required for the production of nitric oxide (NO), a molecule involved in regulating blood pressure.
Can L-Arginine Lower Blood Pressure?
Some studies suggest that L- arginine may lower blood pressure. A 2017 study looked at the effect of L-arginine on blood pressure in people with arterial hypertension (high blood pressure). Results showed that people taking L-arginine experienced significant reductions in systolic (upper) and diastolic (lower) blood pressure.
Another 2018 study looked at the effect of L-arginine on blood pressure in people with hypertension. The results showed that people taking L- arginine had a significant reduction in systolic blood pressure but no significant reduction in diastolic blood pressure.
There are some studies that suggest L- arginine may lower blood pressure. However, the results are inconclusive and there is not enough scientific evidence to confirm that L-arginine lowers blood pressure. Therefore, it is important that more studies are conducted to better understand the effects of L-arginine on blood pressure.
