An investigator initiated pilot study: two arm, double blind, placebo controlled, randomized, group of approximately 60 patients undergoing a kidney transplant. Participants will be treated with human milk oligosaccharide (HMO) prebiotic versus placebo over 12 weeks from start of the investigational medication date (approximately 3 months) to test whether HMO can improve renal transplant outcomes. Participants will be followed up for 3 months after after they complete the treatment portion of the study. HMO sachets will be administered to determine the safety and efficacy of HMO relative to placebo in improving renal transplant outcomes in patients by reducing delayed graft function and side effects from post transplant therapy.
