were able to take 3.6 grams of curcumin without noting ill effects. At this high dose, some curcumin and its products were found in the blood. Lower doses may be enough to directly affect the stomach and intestine. Even though it does not absorb well into the bloodstream, curcumin absorbs into the colon lining and into cancerous tissues in the colon. Small studies have found most people in study groups were able to take up to 10 grams of curcumin per day for a period of a few weeks without noticing problems other than the large volume of pills. There are also studies going on now that try different ways to formulate curcumin so that it absorbs well enough to be tested in humans. A 2011 study took advantage of the fact that curcumin stays in the intestine rather than absorbing into the blood. Researchers tested it to find out if it could reduce the number of cancer precursors in the colon and rectum. They measured compounds that help promote cancer in rats, did colonoscopies to count abnormal crypt foci (a very early sign that colon cancer may be developing) in biopsy samples, then gave 2 to 4 grams of curcumin a day to 44 smokers. After a month on the curcumin, the researchers did second colonoscopies and biopsies to see if there was a lower concentration of procarcinogenic substances in the colon and rectum. The compounds were at the same level as they were before the study. But the smokers who took 4 grams of curcumin a day had fewer abnormal crypt foci after the study, while the smokers who took 2 grams a day had the same number as before. Researchers are still looking at whether curcumin might actually reduce the number of colon and rectum cancers. Further clinical trials are going on to find out what role, if any, turmeric and curcumin may play in the
