In addition to NO synthesis, l-Arg can also be catalyzed by arginine decarboxylase to produce agmatine [117], which improves EC function by enhancing eNOS activity, reducing mitochondrial ROS levels, and alleviating lipid accumulation through the AMPK/phosphatidylinositol 3-kinase (PI3K)/Akt/eNOS signaling pathway [125, 126]
Clinical trials have shown small reductions in systolic blood pressure rather than increases, and hypertension is not listed as a common adverse effect in the MHRA-approved product information
