Evidence labels

  • EmergingMostly preclinical or early signals; human athletic data is thin.
  • Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
  • Stronger clinical signalSupported by larger clinical trials in defined medical populations.

Same color code everywhere on STACKD: green = stronger clinical/human data, amber = limited human data or mechanism, slate = emerging/anecdotal, and oxblood = an in-house STACKD summary.
