Spermidine and resveratrol both promote autophagy but reach it through different upstream routes: spermidine inhibits acetyltransferases while resveratrol activates the deacetylase SIRT1, converging on the cell's acetylproteome. In human cells, yeast, and nematodes, low concentrations that did nothing alone induced autophagy when combined, so the two are biologically plausible partners. Human clinical evidence for the combination is lacking, so any longevity stack should be treated as a low-stakes complement to diet, sleep, and exercise rather than a proven intervention.
