Intake of MPRO3 over 4 Weeks Reduces Glucose Levels and Improves Gastrointestinal Health and Metabolism.
Ontology highlight
ABSTRACT: Human gut microbiota are involved in different metabolic processes, such as digestion and nutrient synthesis, among others. For the elderly, supplements are a major means of maintaining health and improving intestinal homeostasis. In this study, 51 elderly women were administered MPRO3 (n = 17), a placebo (n = 16), or both (MPRO3: 1 week, placebo: 3 weeks; n = 18) for 4 weeks. The fecal microbiota were analyzed by sequencing the 16S rRNA gene V3-V4 super-variable region. The dietary fiber intake increased, and glucose levels decreased with 4-week MPRO3 intake. Reflux, indigestion, and diarrhea syndromes gradually improved with MPRO3 intake, whereas constipation was maintained. The stool shape also improved. Bifidobacterium animalis, B. pseudolongum, Lactobacillus plantarum, and L. paracasei were relatively more abundant after 4 weeks of MPRO3 intake than in those subjects after a 1-week intake. Bifidobacterium and B. longum abundances increased after 1 week of MPRO3 intake but decreased when the intake was discontinued. Among different modules and pathways, all 10 modules analyzed showed a relatively high association with 4-week MPRO3 intake. The mineral absorption pathway and cortisol biosynthesis and secretion pathways correlated with the B. animalis and B. pseudolongum abundances at 4 weeks. Therefore, 4-week MPRO3 intake decreased the fasting blood glucose level and improved intestinal health and metabolism.
