I started taking Longvida Optimised Curcumin 500mg once a day. It says on the bottle that it is "high absorbtion, free form." This was just a couple of weeks ago. I started with 1 capsule a day to see if my stomach can tolerate it and so far I am ok with that. I will increase it to 2 pills a day. I don't see how it could hurt. Put another way, I am willing to risk it. Thanks for the post.
