PHGG: Long-Term Gut Health Support for IBS and IBD

June 5, 2025

PHGG and Digestive Health

Digestive conditions such as Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD), including Crohn’s disease and ulcerative colitis, can significantly impact daily life. While medications are often essential, adding the right type of dietary fibre may provide extra relief and long-term support.

One of the most promising fibres is Partially Hydrolysed Guar Gum (PHGG), a gentle, prebiotic soluble fibre that supports both gut function and microbiome health.

What the Research Says

A 2024 clinical trial published in the Journal of Medical Investigation (Watanabe et al., 2024) studied the long-term use of PHGG in people with IBS, Crohn’s disease, and ulcerative colitis. Importantly, participants continued their regular medications while taking PHGG for six months.

The results were encouraging:

IBS patients experienced improved stool form (measured by the Bristol scale), higher levels of short-chain fatty acid–producing bacteria (beneficial for gut balance), and reduced levels of Bacteroides, a bacteria often linked to gut dysfunction.
Ulcerative colitis patients showed trends toward stool normalisation and lower calprotectin, an inflammatory marker.
Across all groups, no adverse effects were reported, confirming PHGG’s safety for long-term use.

Why PHGG Works

Unlike harsh fibres, PHGG is:

Gentle and well-tolerated – won’t trigger gas or bloating in most people.
Prebiotic - feeds beneficial bacteria that produce short-chain fatty acids for gut health.
Anti-inflammatory - linked to reduced gut inflammation in clinical trials.
Complementary - works alongside standard treatments for IBS and IBD.

Unlike other digestive supplements, PHGG does not form a thick gel.

This makes PHGG more than just a fibre for regularity, it actively supports the gut microbiome, calms inflammation, and improves overall digestive comfort.

How to Use PHGG Daily

Propel Health PHGG is a taste-free, soluble powder that dissolves easily into water, smoothies, or food. It’s simple to take every day as part of your routine.

Alongside PHGG, lifestyle factors like stress management, sleep, and physical activity all play a role in gut health. Pairing these with the right nutritional support can make a noticeable difference.

Choose Independently Tested Supplements

Plant-based supplements are only as good as the ingredients they contain.

Because glyphosate is widely used in modern agriculture, trace residues have been detected in a variety of crops and foods.

For many people, independent testing provides an extra level of confidence that a supplement is as clean as possible.

When choosing plant-based supplements, look for brands that are transparent about contaminant testing, not just active ingredients, so your supplement supports your health without unnecessary exposure to unwanted residues.

Key Takeaway

PHGG has strong clinical evidence as a safe, effective, and well-tolerated option for IBS and IBD support. By improving microbiome balance and reducing inflammation, it’s a practical long-term solution for gut health.
