PHGG is our popular prebiotic fibre supplement, derived from the seeds of the guar plant which have undergone an enzymatic process to make them highly accessible as a fuel for the microbiota.
It is a flavourless, colourless and heat-stable powder so it can be used in a variety of situations such as in hot drinks, smoothies, breakfasts and baking.
As a prebiotic fibre, it does not contain any FODMAPs or excipients, so it is well tolerated in individuals with small intestinal bacterial overgrowth (SIBO), irritable bowel syndrome, constipation and other bowel symptoms.
PHGG is a favourite with clinicians, due to its long chains of galacotomannans, which is a favoured fuel source for key short-chain fatty acid producing bacteria such as Ruminococcus, Faecalibacterium, Bacteroides, and Bifidobacterium.
PHGG is high in fibre, which is often lacking in modern western diets. Fibre can be used to bulk faecal movements, both in cases of constipation and diarrhoea. Dietary fibre can be helpful to increase satiety.

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.
