Natural Factors Natural Factors - Organic Reliefibre, 200 grams
Natural Factors Organic Reliefibre - Unflavoured - 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
Best suited to: reacts badly to inulin or chicory root, wants fibre in coffee or soup, finds psyllium too gritty to drink, giving fibre to a child over 8.
What the research supports
Each 5 g scoop is one ingredient: organic partially hydrolyzed guar gum. It dissolves clear instead of gelling, and the 200 g tub holds 40 scoops.
Trials use 5 to 10 g of guar gum fibre daily.
- Stool regularity (evidence: moderate, from randomized controlled trial)
- The fibre absorbs water and adds bulk to stool, which is why trials at 5 to 10 g daily firm up loose stools and soften hard ones.
- Gas and bloating (evidence: moderate, from randomized controlled trial)
- Guar fibre ferments slowly in the colon, producing less gas than faster fibres like inulin at the same amount, which matters for a sensitive gut.
- Gut bacteria (evidence: moderate, from randomized controlled trial)
- Colonic bacteria ferment this fibre into short chain fatty acids, and human feeding studies near 5 g daily have raised counts of beneficial strains like Bifidobacterium.

Is it right for you
Worth it if
- Reacts badly to inulin or chicory root
- Guar fibre ferments slowly and further down the colon than inulin, and it tests low in FODMAPs where inulin does not.
- Wants fibre in coffee or soup
- It is unflavoured and dissolves clear, and the tub holds nothing but the guar fibre itself.
- Finds psyllium too gritty to drink
- Hydrolyzed guar dissolves fully rather than swelling into suspended husk particles.
- Giving fibre to a child over 8
- The label sets a single 5 g serving daily for children over 8, the same one scoop an adult takes.
Look elsewhere if
- Needs a big bulking effect for hard stools
- Psyllium husk at 5 to 10 g adds far more stool bulk per gram and costs a fraction as much.
- Trying to hit 30 g of daily fibre from one product
- One scoop covers 5 g of a 25 to 38 g daily target, so build the rest from food or a bulk psyllium or wheat dextrin tub.
- Wants a fibre that fills the stomach before meals
- Glucomannan gels thickly in water and is the fibre used for that; this one is engineered specifically not to.
What to expect
Stool form and regularity usually shift within 3 to 7 days of daily use, and the label says to check with a practitioner if nothing has changed in seven days. Unlike inulin, most people do not get a gas spike in the first few days, though starting at one scoop rather than two is still the sensible way in.
How it compares
- Compared with psyllium husk powder
- It dissolves clear and never thickens, so it mixes into anything hot or cold without the slime psyllium develops within a minute of sitting. The tradeoff: Psyllium adds much more stool bulk per gram and is one of the cheapest fibres on the shelf, so you are paying a real premium here for texture and slow fermentation.
- Compared with an inulin or FOS prebiotic powder
- Guar gum ferments slowly and evenly rather than rapidly in the upper colon, which is where the gas from inulin comes from. The tradeoff: Inulin feeds Bifidobacteria harder and costs less per gram, so if you tolerate it there is not much reason to switch.
