This is what I take. It is made by Life Extension. Have any of you read any info on Bioperine? I actually found some really interesting and encouraging info about it's additive benefits.Here is a link to read about it: http://www.bioperine.com/usage_advantage.htmThere are several sub-links as well on the site with alot of info about it. I know with CF'ers our big problem is with the ADEK's and Bioperine helps ais in the absorption of these, as well as other vitamins and minerals (and Curcumin!) Just wanted to share!Jen 34 w/cf
