After scouring the Web, I found the attached Theracurmin brand to be the best (90 mg curcumin/pill) and least expensive ($1.41/day) for a full dose of 90 mg twice a day as in the Study mentioned above. See attached screenshots.
1st Option $1.41/day for 180 mg in 2 pills
My Health Store
2nd option $1.50/day for 180 mg in 2 pills
Professional Supplement Center
Amazon has 60 tablets for $ 53, or $1.77 per day. I went ahead and ordered it myself based on the studies and comments. Since I still have a supply of Meriva, I will alternate doses with Theracumin until I have used up the Meriva.
