PHGG (Partially Hydrolysed Guar Gum)
PHGG, short for Partially Hydrolysed Guar Gum, is a soluble dietary fibre derived from guar beans. It is produced by enzymatically breaking down guar gum into smaller, more easily tolerated fibre molecules.
Unlike many traditional fibres, PHGG is low in viscosity, meaning it dissolves easily in water and is generally well tolerated, even by people with sensitive digestion.
What is PHGG?
PHGG is a form of soluble fibre created by partially hydrolysing (simply, break down) guar gum, a natural fibre extracted from guar beans (Cyamopsis tetragonoloba).
The hydrolysis process reduces the thickness and fermentative intensity of guar gum, making PHGG:
- Easier to digest
- Less likely to cause bloating
- Suitable for daily use
PHGG is colourless, tasteless, and dissolves clearly in liquids, which makes it practical for long-term supplementation.
How PHGG works in the body
PHGG passes through the small intestine undigested and reaches the large intestine, where it is slowly fermented by gut bacteria.
This gradual fermentation:
- Supports the production of short-chain fatty acids (SCFAs)
- Encourages the growth of beneficial gut microbes
- Helps maintain regular bowel function
Because PHGG ferments slowly, it is generally better tolerated than rapidly fermenting fibres, which can cause gas or discomfort in some people.
Common uses of PHGG
PHGG is commonly used as a daily fibre supplement to support:
- Adequate dietary fibre intake
- Digestive comfort
- Gut microbiome balance
- Regular bowel habits
It is often chosen by individuals who do not tolerate more aggressive fibres well.
PHGG compared with other fibres
PHGG differs from other common fibres in several ways:
- Compared to psyllium: PHGG is lower in viscosity and less likely to cause bloating.
- Compared to inulin: PHGG ferments more slowly and is often better tolerated.
- Compared to wheat-based fibres: PHGG is gluten-free and suitable for a wider range of dietary preferences.
For a detailed comparison, see our article comparing PHGG with other fibre types.
Is PHGG safe?
PHGG is generally well tolerated when used as part of a balanced diet.
As with any fibre, introducing PHGG gradually and consuming adequate fluids is recommended.
A rule of thumb is:
"Start low. Build slow."
Individuals with existing gastrointestinal conditions or those taking medications should consult a qualified health practitioner before use.
Where to buy PHGG
PHGG is available as a standalone fibre supplement.
