Summary
Brief summary
Probiotics are defined as live microorganisms which when administered in adequate amount confer a health benefit on the host. The probiotic efficacy relies on their ability to survive in the digestive system and proliferate in the gut. The aim of this study is to investigate the survival of LcS in the intestine of healthy Australian adults after intake of fermented milk (Yakult). A single-arm, open-label study involving 25 otherwise healthy adults will examine the recovery of live culturable bacteria from faecal samples following 7 and 14 days of Yakult ingestion.
