GLP-1 Fibre Supplement
A GLP-1 fibre supplement has one extra test to pass: it has to fit into a day of smaller meals and smaller drinks.

The test most fibre comparisons skip: the glass
People on GLP-1 medicines usually eat less and often drink less. Fibre comes with food, so it drops too. The Australian adequate intake is 25 g of fibre a day for women and 30 g for men (NHMRC), and a 2025 joint nutrition advisory for people on these medicines suggests adding fibre gradually, with plenty of fluid.
Most fibre comparisons look at grams and price. For a GLP-1 user, the first question is simpler: how much do I have to drink to get it down?
GLP-1 fibre supplement: how much liquid each one needs
| Product | Mixes into | Texture | Taste |
|---|---|---|---|
| PHGG | Any drink, including a coffee | Stays thin | None |
| Gut Health Plus | Any drink | Stays thin | None |
| Organic inulin | Any drink | Thin | Lightly sweet |
| Gut Health Powder | A full glass | Thickens | Flavoured |
| Psyllium husk | A full glass, drunk straight away | Swells into a gel | Mild, grainy |
Fibre supplements for GLP-1 users: grams and cost
Every comparison on this site uses the same numbers: grams of fibre (or protein) in a serve, what that serve costs, and what 10 g of fibre costs. A bigger number is not automatically a better product. The point is to see the numbers and know what you are paying for.
| Product | Serve | Fibre per serve | Cost per serve | Cost per 10 g fibre |
|---|---|---|---|---|
| PHGG | 6 g | about 5 g | $0.93 to $0.99 | $1.86 to $1.98 |
| Gut Health Plus | 6 g | about 5 g | $1.26 to $1.57 | $2.52 to $3.15 |
| Organic Inulin | 5 g | 4.5 g | $0.40 to $0.50 | $0.89 to $1.12 |
| Gut Health Powder | 8 g | 4.1 g | $1.46 to $1.83 | $3.56 to $4.47 |
| Psyllium Husk | 4 g | 3.5 g | $0.19 to $0.24 | $0.54 to $0.68 |
Fibre from our 2025 labels. Cost per serve runs from the best value pack to the single jar. Cost per 10 g of fibre is the cost per serve divided by the fibre in it, times ten.

Which to choose on a smaller day
- Least to drink, no taste: PHGG.
- PHGG with 1 billion CFU of Bacillus coagulans per 6 g serve: Gut Health Plus.
- Lowest cost per 10 g of fibre, if a full glass is easy: psyllium husk.
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.
Start with a teaspoon
Whichever you choose, start with about a teaspoon a day and add a teaspoon every 2 to 3 days up to the full serve on the label. Drink an extra glass of water each time, spread through the day if needed. Building up slowly is the reason for the small first step.
| Pack | Price | Serves | Per serve |
|---|---|---|---|
| 300 g jar | $49.55 | 50 | $0.99 |
| 300 g, 2 pack | $96.00 | 100 | $0.96 |
| 300 g, 3 pack | $141.00 | 150 | $0.94 |
| 300 g, 4 pack | $186.00 | 200 | $0.93 |
GLP-1 fibre questions
Which fibre supplement suits a GLP-1 user?
The one you will actually take on a small day. For most people that is PHGG, because it dissolves into any drink with no taste. If a full glass of water is easy, psyllium husk costs the least.
How much should I start with?
About a teaspoon a day, then a teaspoon more every 2 to 3 days up to the full serve on the label, with an extra glass of water each time.
Can I take fibre with a GLP-1 medicine?
Fibre supplements are foods. Ask your doctor or pharmacist about anything to do with your medicine before adding something new.
These products are foods, not medicines. Keep every decision about your medicine with your doctor.
