Arginine aids in the creation of nitric oxide which helps to regulate your body’s blood pressure. Nitric oxide does this by relaxing your blood vessels to relax, causing them to widen and allow more blood flow.
Researchers found that two grams a day of L-arginine ingested by mouth for one week caused close to a 20 point drop in systolic blood pressure, which they attributed to l-arginine.
Another study showed Compared with a placebo, L-arginine intervention significantly lowered systolic BP by 5.39 mm Hg and diastolic BP by 2.66 mm Hg with a duration starting at 4 weeks
Conclusions: This meta-analysis provides further evidence that oral L-arginine supplementation significantly lowers both systolic and diastolic BP. 
First found in watermelon, Citrulline is an amino acid that when consumed is partially converted to a separate amino acid named arginine. Arginine then turns into nitric oxide, which causes the blood vessels to relax and lower your blood pressure and increase blood flow.
One study even found that consumption of citrulline may potentially increase arginine levels more than taking actual arginine.
