The aim of this study is to assess the feasibility of β-hydroxybutyrate (BHB) supplementation in individuals who are undergoing a standard-of-care colonoscopy or flexible sigmoidoscopy in order to determine whether BHB supplementation is safe and tolerable. Additionally, this study will determine whether BHB supplementations increases serum BHB levels, and leads to transcription and protein expression changes in the colonic mucosa. BHB supplementation will be performed through oral administration of HVMN Ketone-IQ, a commercially available BHB supplement, with an active ingredient of R-1,3-Butanediol, which gets converted to BHB.
