Backed by research, trusted by professionals
PHGG is one of the most clinically studied natural fibres, with over 20 human trials showing benefits for digestion, stool regularity, and microbiome balance.
A highly soluble heat-stable prebiotic
PHGG is a heat-stable, highly soluble prebiotic that can be baked into foods, added into smoothies or dissolve into any drink hot or cold, without clumping.
- FODMAP-friendly and well-tolerated
- Supports both constipation and loose stools
- Encourages growth of beneficial bacteria like Bifidobacteria & short chain fatty acids.
Give your gut the support it deserves with science-backed PHGG fibre – gentle, effective, and designed for real life.
Mix 5g (3 tsp) daily into beverage of choice (hot or cold) or add to food.
Do not exceed the recommended dose, unless advised by your healthcare professional.
Suitable from 6 months
PHGG is normally well tolerated, but if you have a sensitive stomach, start with half a dose and build up gradually to the full dosage.
PHGG has been consumed by pregnant and lactating women for years, and it has been shown to be a safe way to improve regularity and reduce cramping and bloating. As with any supplement, however, please consult with your health care practitioner prior to use if you are pregnant or breastfeeding.
FAQs
We decided to switch the type of PHGG we use to an ‘agglomerated’ grade. This means that the fibre dissolves much more easily in colder temperature water and is easier to take.
The recommended serving size is still the same – 5g. Because the density of the agglomerated PHGG is lower, 5g is approximately 3 teaspoons.


PHGG is a valuable addition to my Paediatric Naturopathic tool kit.
A gentle, well-tolerated prebiotic fibre that supports stool regularity, gut microbiota diversity, and mucosal health, even for my most sensitive clients.
It dissolves easily into liquids or foods without taste or texture issues, which significantly improves compliance in my younger clients. The updated formulation is ideal for therapeutic use, dosing can be titrated to suit even the most sensitive tummies.
I appreciate Invivo’s continued commitment to clinical-grade, practitioner-trusted products. Another gem! Thanks team.
