Why GLP-1 users look at fibre
GLP-1 medicines usually mean smaller meals. Fibre comes with food, so when meals shrink, fibre shrinks too. The Australian adequate intake is 25 g of fibre a day for women and 30 g for men (NHMRC). A day of small plates can fall well short of that.
Dietary studies of people on GLP-1 medicines have found fibre intakes below recommended levels, and a 2025 joint nutrition advisory for people on these medicines suggests adding fibre gradually, with plenty of fluid.
For a full day of small meals, see what to eat when you are not hungry on Propel Health Australia, and the whole fibre range on Supplements for GLP-1 Users.
PHGG for GLP-1 users: why it fits a smaller day
- No meal needed: it stirs into coffee, tea or water
- No taste and no smell
- Dissolves clear and stays thin, so there is nothing to drink in a hurry
- One ingredient, so a teaspoon is a simple, measurable start
Dietary fibre contributes to regular laxation.
Each 6 g serve of our PHGG provides about 5 g of dietary fibre, making it a good source of dietary fibre. Enjoy as part of a healthy diet that includes a variety of foods.
The teaspoon plan
| Days | How much | About |
|---|---|---|
| 1 to 3 | 1 teaspoon | 1.5 g |
| 4 to 6 | 2 teaspoons | 3 g |
| 7 to 9 | 3 teaspoons | 5 g |
| 10 onward | 4 rounded teaspoons | 6 g, the full serve |
Drink an extra glass of water after each serve. If your medicine dose has just gone up, stay on the same step for a few more days before moving on. As with any food that contains fibre, PHGG may cause abdominal discomfort in some people, which is the reason for the small first step.

Questions from GLP-1 users
Can I take PHGG on a GLP-1 medicine?
PHGG is a food: a single soluble fibre. If you have questions about your medicine, ask your doctor or pharmacist before adding anything new.
How much should I start with?
1 teaspoon a day. Add a teaspoon every 2 to 3 days until you reach 4 rounded teaspoons (6 g), the full serve on our label.
What do I mix it with?
Anything you are already drinking: coffee, tea, water, juice or a small smoothie. It dissolves clear with no taste or smell.
Do I still need the extra glass of water?
Yes. Our label advises an extra glass of water after each serve. If a full glass at once is a lot, sip it through the morning.
How long does a jar last?
A 300 g jar is 50 full serves. During the first fortnight of teaspoon steps it lasts longer.
PHGG is a food, not a medicine. Keep every decision about your medicine with your doctor.
