Curcumin is a polyphenol, but it appears to be a particularly gifted one. There have been over 2,000 studies where it's proven to be a potent warrior against cancers of the prostate, breast, liver, colon, lung, and pancreas, to name a few. And unlike conventional chemotherapy agents, it doesn't harm healthy cells.
Curcumin has been shown to modulate tumor growth through regulation of multiple cell signaling pathways including cell proliferation pathway (cyclin D1, c-myc), cell survival pathway (Bcl-2, Bcl-xL, cFLIP, XIAP, c-IAP1), caspase activation pathway (caspase-8, 3, 9), tumor suppressor pathway (p53, p21) death receptor pathway (DR4, DR5), mitochondrial pathways, and protein kinase pathway (JNK, Akt, and AMPK).
Unfortunately, the body doesn't absorb curcumin very well. Simply ingesting it as a main constituent of curry powder, regardless of the amount eaten, isn't going to have much of an effect.
As such, you need to ingest curcumin as part of a formula that contains piperine, which enhances absorption by up to 2000 percent. Go with Biotest Curcumin.
