Turmeric is not the same as curcumin which I relaized until I called these folks to place an order. I had been using a major store brand without knowing that the label says 400 mg turmeric roor and 100mg curcumin and the product is called turmeric-curcumin 500.very deceptive advertising. Turmeric is almost 25 times diluted and curcumin is extracted from it. Great customer service, they took time to explain in detail especially my wife has been taking for a few years to prevent recurrence of breast cancer. Check the label before you buy at other places. I strongly recommend physician naturals as they have so many curcumin supplements and their service is excellent.
