Effects of an Encapsulated Calcium Butyrate Dietary Supplement on Gut Health

Completed · Not applicable

Conditions studied: Healthy, Gastrointestinal Discomfort

In brief

The primary objective of this single-arm pilot study is to investigate the effects of an encapsulated calcium butyrate dietary supplement on gastrointestinal (GI) health outcomes in healthy adults, including GI symptom severity (e.g., gas/flatulence and abdominal bloating), bowel habits (frequency and consistency), digestion-associated quality of life, and measures of GI permeability.
