Luteolin, a naturally occurring flavonoid, has a robust amount of experimental data both in vitro and in vivo revealing a variety of anti-cancer mechanisms. 1,2,3,4 Rutin, also a naturally occurring flavonoid, has strong evidence demonstrating its ability to enhance cancer cell death by upregulating the genes involved in apoptosis and those involved in arresting cell-cycle progression.5,6,7 Epigallocatechin-3-gallate (EGCG), a polyphenol naturally occurring in green tea, has been extensively studied for decades for its anti-cancer properties.8,9 Proprietary internal data obtained from in vitro experiments by Young Ko, Ph.D., and colleagues, at her KoDiscovery lab, have demonstrated a synergy in killing cancer cells when Luteolin, Rutin and EGCG are combined in a specific ratio. KoFactor1 contains this proprietary ratio of luteolin, Rutin and ECGC aimed to maximize benefit.
