Natural Factors Natural Factors - Organic Reliefibre - Tropical 5 g, 268 grams
Natural Factors Organic Reliefibre - Tropical Flavour - Low FODMAP fibre sourced from guar gum provides relief for IBS and intestinal discomfort such as diarrhea, constipation, gas and bloating. Fibres such as psyllium, inulin, bran and wheat are high FODMAP short-chained fermentable carbohydrates which are troublesome for IBS and the digestive system. Natural Factors Reliefibre dissolves completely, without grit.

Why people keep reordering it
- Researched strains
- Specific, studied strains at counts high enough to reach your gut.
- Guaranteed live cultures
- Potency held through the end of shelf life, not just at manufacture.
- Digestive balance
- Supports regularity, bloating and a healthy gut barrier.
Best suited to: will not drink an unflavoured fibre daily, reacts to inulin, psyllium or wheat bran, wants a sweetened fibre with no sugar, giving fibre to a child over 8.
What the research supports
Each scoop is 6.7 g, but the fibre is still 5 g: the rest is tropical flavour, citric acid and stevia. The 268 g tub holds 40 scoops.
Trials use 5 to 10 g of guar gum fibre daily.
- Stool regularity (evidence: moderate, from randomized controlled trial)
- This fibre absorbs water and adds bulk to stool, and trials at 5 to 10 g daily have firmed up loose stools and softened hard ones.
- Gas and bloating (evidence: moderate, from randomized controlled trial)
- Guar fibre ferments slowly, producing less gas at the same amount than faster-fermenting fibres like inulin, which matters for a reactive gut.
- Gut bacteria (evidence: moderate, from randomized controlled trial)
- Colonic bacteria ferment this fibre into short chain fatty acids, and human studies near 5 g daily have raised counts of beneficial strains such as Bifidobacterium.

Is it right for you
Worth it if
- Will not drink an unflavoured fibre daily
- Fibre only works if you take it, and the stevia and tropical flavour turn a glass of water into the delivery vehicle rather than a chore.
- Reacts to inulin, psyllium or wheat bran
- Guar gum ferments slowly and tests low in FODMAPs, which the wheat and chicory fibres do not.
- Wants a sweetened fibre with no sugar
- Sweetness comes from stevia leaf extract only, with no sugar and no sugar alcohols anywhere in the tub.
- Giving fibre to a child over 8
- One 6.7 g serving daily is the labelled children's amount, and flavour matters more at that age than at any other.
Look elsewhere if
- Adding fibre to coffee, soup or oatmeal
- The unflavoured version of this same guar fibre has no flavour, acid or stevia in it and disappears into anything, hot or cold.
- Avoiding stevia or added acids
- Take the unflavoured tub, which is guar gum on its own with nothing else added.
- Needing stool bulk more than tolerability
- Psyllium husk bulks far more per gram at a much lower price, if your gut handles it.
What to expect
Changes in stool form and regularity usually appear within 3 to 7 days of daily use. It barely thickens, but the citric and malic acid give it a tart edge, so mix it into a full 250 mL rather than a small glass.
How it compares
- Compared with the unflavoured Reliefibre tub
- It tastes like a light tropical drink instead of nothing, which for a lot of people is the difference between a fibre taken daily and one that stalls in the cupboard. The tradeoff: You are locked into one flavour, you cannot stir it into coffee or savoury food, and 1.7 g of every scoop is flavouring you did not come for.
- Compared with psyllium husk
- It dissolves clear with no grit and no gel, so it goes down like a drink rather than something you have to chase with more water. The tradeoff: Psyllium costs far less per serving and adds considerably more stool bulk per gram.
