Microbial Enzyme Impact on Postprandial Nutrient Levels and Gastrointestinal Symptoms in Healthy Adults

Completed · Not applicable · Has a placebo group

Conditions studied: Digestive Health, Gastrointestinal Health

In brief

The primary objective of this study is to investigate the acute effects of a microbial multi-enzyme mixture ("BC-006") on postprandial nutrient levels in healthy, middle-aged to older adults during a mixed meal tolerance test. Additionally, the effects of twice daily consumption of BC-006 and placebo for 3 weeks on abdominal bloating, flatulence, bowel function, and sleep quality will be measured.
