The hypothesis of an effect of testosterone rise in the l-ARG-mediated improvement of penile erectile function, at least in the mildmoderate vasculogenic ED patients enrolled within the current study, might be partially supported by the evidence of a trend towards increased testosterone levels upon l-ARG supplementation in the overall l-ARG cohort, although testosterone levels were not significantly improved and were already within the normal range at baseline, therefore partially smoothening this hypothesis

Supports metabolism and active lifestyle goals

Propionic acid directly impairs the metabolism of carnitine in the body, and also causes a reduction in omega-3-fatty acid levels (which leads to reduced antioxidant capacity and other negative impacts on carnitine reuptake)
