I take a turmeric/curcumin supplement made by a top, long-trusted vitamin and supplement company. I am meticulous in reading the label regarding sources, and what is and is NOT in the capsule. I take a medium dose, and it has shown to be very effective for me in my blood tests and in alleviating my symptoms when combined with other anti-inflammatory supplements, such as extra-virgin olive oil (EVOO), garlic, ginger, vitamin D3, and Omega-3 fish oil.
