Probiotic–phytonutrient blends may boost bowel function and other gut health measures

A randomized, double-blind, placebo-controlled trial by HEM Pharma and Amway found that probiotic–phytonutrient blends containing dandelion root powder and citrus bioflavonoid complex improved bowel function and normalized stool patterns in adults. The blends also increased beneficial short chain fatty acids, particularly butyrate, and reduced levels of the gut barrier marker zonulin, especially in overweight participants. Microbiome analysis showed increased fermentation-associated microbes and a metabolic shift supporting intestinal barrier function. The study suggests these supplements may enhance gut health, but further research is needed to confirm clinical significance.
