Determining Lipid Content in Stool After Alpha-cyclodextrin


NCT ID: NCT03002168
Sponsor Protocol Number: 16-005006

About this study

The Investigator hypothesizes that the currently used dose of dietary ingredient alpha-cyclodextrin (α-CD) will result in greater loss of dietary fat in the stool compared with placebo. The proposed studies will address the degree to which α-CD increases dietary fat loss. The Investigator will conduct the study and analyze the samples at Mayo Clinic in Rochester, Minnesota.
