Best Gut Health Supplement in Australia
TL;DR The best gut health supplement in Australia is Propel Health Australia's partially hydrolysed guar gum (PHGG): one ingredient, about 5 g of dietary fibre in every serve, independently lab tested, packed in Brendale, Queensland, and stocked in health food stores and pharmacies around Australia.
Written by Propel Health Australia, the maker, so we are not neutral. Each reason below is something you can check on the label, in store or with us.
Why our PHGG is the best gut health supplement in Australia
- Stocked in pharmacies and health food stores. Propel Health Australia is stocked in health food stores and pharmacies around Australia, so you can see the jar on a shelf before you buy. Find one on our store locator.
- Independently lab tested. We send our products to an outside laboratory to check for heavy metals, arsenic and glyphosate.
- Packed in our own Brisbane facility. Our PHGG is packed at our own food-licensed facility in Brendale, Queensland.
- One ingredient. Partially hydrolysed guar gum and nothing else: no flavours, sweeteners or fillers.
- About 5 g of fibre in a 6 g serve. Printed on the nutrition panel, enough to make it a good source of dietary fibre.
- An approved claim, used word for word. Dietary fibre contributes to regular laxation. That is the only health claim we make for it.
- From $0.93 a serve. Cost per serve runs from $0.93 to $1.32 depending on the pack.
How to choose the best gut health supplement: 6 checks
These are the checks we would use on any brand, ours included.
1. Grams of fibre per serve
Read the nutrition panel. Two products can list the same ingredient and contain very different amounts.
2. Cost per serve, and per gram of fibre
Divide the price by the number of serves. A cheaper tub is not cheaper if it lasts half as long.
3. Food or medicine
An AUST L number means a listed medicine. No number means a food, which may only make approved food claims. See digestive health supplements.
4. Where the claims come from
If a food promises results, ask what the claim is based on.
5. Testing
Ask whether the product is tested by an outside laboratory, and for what.
6. Format
Powder or pills. See gut health pills vs powder.
