The increasing interest in natural products for cancer prevention has led to a provocative exploration of Kratom (Mitragyna speciosa) as a potential chemopreventive functional food. This perspective synthesizes current knowledge on Kratom's rich phytochemical profile—dominated by alkaloids (mitragynine, 7-hydroxymitragynine) alongside flavonoids and phenolics—and examines their molecular actions in cancer-related pathways. In vitro evidence demonstrates that Kratom alkaloids induce selective apoptosis, arrest cell cycle progression, inhibit migration and clonogenicity, and synergize with chemotherapeutic agents. Non-alkaloidal constituents, such as rutin and procyanidin, exhibit antioxidant activity and topoisomerase IIα inhibition, further contributing to anticancer effects. The review critically assesses bioavailability challenges, metabolic transformations, and safety concerns, including psychoactive properties and drug–food interactions. Regulatory and standardization hurdles are discussed, highlighting the need for batch consistency, toxicity profiling, and harmonized legal frameworks for psychoactive botanicals. Finally, strategic recommendations for future research are proposed: controlled human trials, advanced formulation techniques to enhance bioavailability, fair-trade sourcing, and consumer education to overcome stigma. This work argues that, with rigorous standardization and safety validation, Kratom holds promise as a novel multi-target functional food for cancer chemoprevention. © 2025 The Authors.
