I Am Taking Tumeric And F______ As A Dietary Aid

I am taking tumeric and f______ as a dietary aid to lose weight (I forget the name of the second key ingredient) and I just read in the AARP newspaper that curcumin is good to take for a healty brain. I didn't realize tumeric & curcumin are the same thing, but your info on tumeric indicates that they are. Will the weight loss aid also ahelp my brain or should I look for curcumin for that? Also, I noticed a slight burn in my throat after I took the tumeric. Is that normal?
