Nutrition Supplement for Cystic Fibrosis

The goal of this study is to learn if one nutrition supplement formula works better than a different formula in adults with cystic fibrosis. The main question being addressed is: Will certain atypical versions of certain nutrients outperform typical versions of these nutrients? This will be determined by examining blood measures of nutrient levels and/or indications of nutrient function indicators pre- and post-intervention. Participants will take the supplements for 6 weeks with a blood draw before and after that time.
