Core Tip	This letter critiques Mansouri et al's study on L-arginine (L-Arg) in diabetic cardiomyopathy, revealing dose-dependent cardiotoxicity: While low doses (0.5 g/kg) may modestly improve lipid profiles, higher doses (≥ 1 g/kg) exacerbate myocardial injury via prooxidant [nuclear factor E2-related factor (Nrf-2) depletion] and proinflammatory (inducible nitric oxide synthase-driven peroxynitrite) mechanisms. The findings challenge the perception of L-Arg as universally safe, especially in diabetics with endothelial dysfunction. Urgent clinical translation is needed to validate safe thresholds in humans, alongside tailored guidelines for vulnerable populations. Future research should prioritize human trials, combination therapies (e.g., Nrf-2 activators), and regulatory frameworks for supplement standardization.
