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
Yes – in a compost environment the pouch will break down in 26 weeks into water, co2 and biomass, just like other organic materials such as paper. This pouch has been independently tested and accredited for eco-toxicity, disintegration, and biodegradation to known standards such as OK Compost Home, Seedling, ABA and Cré. Because the zipper is ‘Industrial’ compost certified only, this means the process may take longer than 26 weeks for this part of the pouch.
The pouch is designed to compost completely under normal home conditions in 26 weeks. This may vary according to conditions in your compost heap, and the zip-lock may take a little longer. Alternatively, the zipper can be cut off and composted in council-collected food waste.
You can, but bear in mind that the pouch is designed to degrade once it comes into contact with moisture and oxygen. PHGG in an open pouch will start to absorb moisture and may clump, so we recommend decanting this into an airtight container as soon as possible after opening. Please ensure your container is completely dry before refilling and ensure that it is labelled correctly.
I love this product so much. Its so soluble and flavourless so it mixes brilliantly into any food or drink. Pre.Bio PHGG has become an easy part of my daily routine
If I was stranded on a desert island and I was only allowed to take one supplement with me, PHGG would be the one. My family and I take PHGG every day in our cup of tea first thing. When we take it, we have far better resilience to coughs and colds that are going round, our digestion feels good and things don’t go wrong. Its great for stabilising and maintaining consistently healthy bowel movements and of course feeding our microbiome gardens! As a Health Practitioner, this is my go to foundational product for most of my clients too.
As a Registered Nutritional Therapy practitioner, I have used this product for myself, my family, and clients for a long while. It has broad clinical application for gut as well as whole body health, and incredible practicality being a flavourless powder which mixes well into any food or drink, which altogether makes it an invaluable tool for both clinical practice and daily life. As with any prebiotic, just be sure to introduce it low and slow. Highly recommend!
PHGG is a staple in my house. I use it daily myself in my evening cuppa, and I add it to my children’s smoothies, pancake batter and baking. It’s so versatile, is tasteless and mixes well for the fussiest of eaters. I use it in my clinic as well for conditions such as SIBO, constipation and loose bowels. It’s great if you’re wanting to increase your gut microbiome diversity in a gentle, fuss free way. I always suggest starting low and slow, and building up to the 3 tsp recommendation to ease your gut into it.
PHGG is my number one go-to for clients and my own gut health. It is well tolerated and easy to integrate into your daily routine, I can’t recommend it more!
Unlike the previous fibre powders I used, this one actually does what it says – it dissolves perfectly into my morning cup of tea and genuinely does not change the taste or consistency!
As a health practitioner who specialises in gut health, this is my number one supplement that I tend to use in clinic to improve gut health and microbial diversity. It is well tolerated even by those sensitive to high FODMAP foods. I have been using the new formula for a while and love how it mixes into hot drinks – it’s a keeper for me as part of my daily gut health routine.
I have been using PHGG for a couple of months now and I am definitely beginning to see the benefits.
So glad to see it now comes in the tin and pouch refills to keep consistent! Thanks team.
