Last month, I stopped taking it and most of the other supplements that I have been on for the last 3.5 years. I took 1800 mgs a day with pepperdine. Have no idea if it did anything and I have been better since I stopped not that that means a thing.
Tumeric/curcumin is hot as far as articles and sales. The "proof" is pretty thin that it will do something. Some test tube research, small trials and lots of speculation. I am kind of down on most supplements at the moment. Lack of clinical trials and testing. Lack of quality control and safety testing. I stopped at first to give my body a rest in case one of them was causing cancer or something but might not start them again. UC is such a crazy disease and the rx drugs not the most effective that self experimentation with supplements and asking other sufferers is probably going to get limited information of value. Effects are going to be subtle, you could just happen to spit blood or get a stomach ache the next day...
I think it might be a good idea to limit ingestion of supplements and vitamins to what you could possibly ingest as food.No way are you going to eat that much tumeric. I take fish oil which has lots of evidence for cardiac and is an amount you could get eating fish, gluclosimine sulfate which I have brainwashed myself into believing got rid of knee pain, a multivitamin, daily homemade VSL#3 yogurt, psllium husk and slippery elm bark for symptoms, and try to eat a varied healthy diet.
I know psllium husk works, lopermide works, pretty positive 5asa works and I really think yogurt, home pickled vegatables etc will help with symptoms and colon health.
The pocket book is definitely an issue too. I use one of the cheaper curcumins(Vitacost) and my dosage runs $240 and rising per year. 3 grams would be almost $500. I was spending $900 a year total for my fist full of pills.
There is some evidence that some antiinflamitories and antioxidants are a double edged sword causing pro-oxidant and inflammation elsewhere in the body which is sort of scary.
I wish some way to fund studies would be thought up.
