I've taken Curcumin for more than two years now, and I have no doubt at all that I can thank it - and Ron - for feeling better now than I did two years ago.
The dosage is 1500 mg per day of Curcumin with Peperine, from IHerb, a web store with the best selection.
I had to start Curcumin slowly, 500 mg per day to begin with, as it cleaned out my system quite thoroughly. It took me several weeks to reach 1500 mg per day without stomach rebellions.
I can recommend it highly.
