Question: are turmeric capsules as effective as the spice?
Answer: In turmeric extracts, the concentration of these is often increased to as high as 95%. Therefore, it is not unusual for a capsule containing half of a gram of turmeric extract to provide 400 mg of curcuminoids, while the same amount of turmeric powder (ground herb -- just like the spice) might provide only about 15 mg.
