What is PHGG (Sunfiber®) and how does it support gut health?

PHGG stands for Partially Hydrolysed Guar Gum. Sunfiber® is a certified FODMAP Friendly, clinically studied form of PHGG that acts as a prebiotic fibre. It dissolves completely in liquid without changing taste or texture, feeds beneficial gut bacteria, supports digestive regularity, and is gentle enough for sensitive digestion including IBS.

What is the difference between a prebiotic and a probiotic?

Probiotics are beneficial live bacteria added to the gut. Prebiotics are fibres that feed and nourish those bacteria. Gentle Fibre is a prebiotic — it does not contain live bacteria itself, but instead creates the right environment for beneficial bacteria to flourish. For a combined prebiotic and probiotic product, see Niche Biotics Gut Balance+.

Is Gentle Fibre suitable for IBS and FODMAP diets?

Yes. Gentle Fibre is certified FODMAP Friendly, making it suitable for people following a low-FODMAP diet for IBS management. Unlike many other fibre supplements, Sunfiber® PHGG does not cause gas or bloating in most people and is specifically designed for sensitive digestive systems.

Does Gentle Fibre change the taste of my drink?

No. Gentle Fibre is completely taste-free and dissolves easily into water, juice, smoothies, yoghurt or meals without altering flavour, texture or appearance. This makes it easy to include in your daily routine without any noticeable difference to your food or drinks.

Is Gentle Fibre vegan and gluten-free?

Yes. Gentle Fibre is vegan friendly, gluten-free and non-GMO. It contains no fillers, flavours, preservatives or artificial additives. Packed in Australia.
