Low FODMAP FIBRE Supplements

Updated: Jun 26, 2019

Have you been told to get more fibre in your diet? Are you following the low FOPMAP diet? While it is important to choose foods that naturally contain fibre, the Low FODMAP diet can reduce your natural fibre intake.

High FODMAP foods attract water into the gut so by removing these foods, there is less water being moved into the gut, effectively drying out the gut. It is not uncommon to get constipation after starting on the low FODMAP diet even if you were suffering from diarrhoea previously!

Fibre is the indigestible part of plant-based carbohydrates, which aids in the health of our digestive system.

You may have come across the terms, soluble and insoluble fibre or resistant starch. Not only does fibre regulate bowel habits and improve constipation, it is also been shown to act as prebiotic, in term of resistant starch, and feed the guts ‘good’ bacteria, aid in satiety (meaning you will stay fuller for longer) and weight management but also aid in maintain healthy cholesterol and blood sugar levels.

Firstly make sure you are getting enough Low FODMAP fibre through food.

Great choices include oats, chia, grainy gluten-free bread, choosing 2-3 low FODMAP fruits spread out over the day such as just ripe banana, pineapple, mandarin (kiwifruit is particularly good and gets the guts moving), keeping up 5 serves a low FODMAP veggies such as carrot, spinach, eggplant, potato, kale and broccoli, choosing lofo nuts such as peanuts, walnuts and macadamia and seeds, and choosing a high fibre low FODMAP brekkie option such as oats or a chia pudding or gluten free Weetbix.

According to the Nutrient Reference Values, males and females over the age of 18, require 30g and 25g respectively of fibre per day. This is easily achieved when eating a variety of plant-based foods each day.

If you have increased your low FODMAP fibre sources, increased your fluids and included exercise but still finding you need a boost to get things moving, then fibre supplements are worth considering. Or even when you have ongoing loose stools then fibre supplements may be worth thinking about.

If you still can't get things moving then consider a fibre supplement. Not all fibre supplements are suitable for the low FODMAP diet, although there are quite a few currently coming on to the market that have great potential- lets explore what is out there..


Psyllium (ispaghula) is a useful supplement, as long as you are drinking enough fluids. Psyllium is a soluble fibre (Metamucil is the same but added flavour and colours).

Start with a small amount, say a teaspoon in a cup of water and build up slowly to 1-2 dessertspoons in 2 cups of water. Thickens on standing so drink straight away. Do not use if you have a swallowing issue or a blockage in the gut..


Monash University low FODMAP certified, and provides 3.4g of fibre per serve, provides relief from both diarrhoea and constipation as well as associated symptoms.

ProNourish natural balance Fibre is unflavoured and easily dissolves into food and beverages. Easy to take as does not thicken on standing.
