Partially Hydrolyzed Guar Gum (Phgg) for Constipation Relief

Research suggests that partially hydrolyzed guar gum (PHGG) may help relieve constipation by improving stool moisture, intestinal transit, and short-chain fatty acid production, while also favorably shifting gut bacterial populations. The available evidence comes from a single preclinical animal study conducted in mice, which found that PHGG performed comparably to established prebiotic fibers in constipation models, with certain molecular weight fractions showing stronger effects than others. Studies indicate a generally supportive direction for PHGG's role in gut health, but the reliance on animal data rather than human clinical trials is a meaningful limitation, and it remains unclear whether these findings would translate directly to human physiology or real-world constipation conditions.
