Hi Bryn or W.W,
We get our Curcumin from Good Health Naturally Telephone 08702414237.I think they have a website. Their Curcumin capsules contain 500mg of Curcumin and 5 mg of Piperine to help to make the active ingredients more available to the body.The price of Curcumin is certainly more reasonable than other supplements. John takes 6 capsules a day which is the maximum dose.He began taking it after I read about Ron taking it, which was soon after diagnoses.
