Wonder Foods Guar Gum — also known as Partially Hydrolysed Guar Gum (PHGG) Sunfiber® — is a premium, low-FODMAP soluble fibre made from the guar bean (Cyamopsis tetragonoloba). Available in both a 150 g starter size and a 300 g daily-use tub, this gentle, slow-fermenting prebiotic fibre is ideal for IBS-friendly gut routines, low-FODMAP plans and everyday digestive support.
Unlike gritty psyllium or fast-fermenting inulin, Wonder Foods Guar Gum PHGG dissolves completely clear, is taste-free and non-thickening. It blends effortlessly into water, smoothies, yoghurt or cooking without altering flavour or texture — making it one of the easiest daily fibres to build into a gut-support routine.
As a Sunfiber®-certified PHGG, Wonder Foods uses a globally recognised raw material known for its purity, consistency and excellent digestive tolerance. Slow fermentation means PHGG produces gas gradually rather than in sharp spikes, helping support comfortable digestion and a more resilient microbiome without triggering the bloating often caused by high-FODMAP or rapidly fermenting fibres. For a deeper dive into how PHGG works, see PHGG Benefits: What the Research Shows.
Wonder Foods is an Australian natural health brand with over 35 years of experience sourcing minimally processed, nutrient-focused ingredients. Their Guar Gum PHGG range is trusted by practitioners for its gentleness, versatility and compatibility with sensitive digestion, including IBS-C, IBS-D and mixed patterns.
