PHGG vs resistant dextrin: both are soluble prebiotic fibres that dissolve without turning into a gel. Resistant dextrin is the easier one to live with. It disappears into food or drink, and in side-by-side lab tests a wheat-based resistant dextrin made less gas than PHGG. That’s why we pick it for an everyday fibre top-up.<\/strong><\/p>\n

You want a daily prebiotic you’ll actually stick with. One box says PHGG, another says resistant dextrin. Both promise to be gentle, and you’ve already had a fibre powder that left you gassy by mid-afternoon.<\/p>\n

Pick the wrong one and you know how it goes: a few days of bloating, the box goes to the back of the cupboard, and the fibre gap stays where it was. SingHealth<\/a> puts the average Singaporean at 13 grams of fibre a day, while HealthHub<\/a> sets the target at 20 g for women and 26 g for men.<\/p>\n

So here’s how the two differ, which one we’d choose for every day, and the few cases where PHGG makes more sense.<\/p>\n\n

What is PHGG (partially hydrolysed guar gum)?<\/h2>\n

PHGG starts life as guar gum, the thickener made from guar beans, which on its own turns water thick and gummy. To make PHGG, an enzyme cuts the gum into much shorter pieces, less than one-tenth of the original length<\/a>. The building blocks stay the same, but the result stays runny in water.<\/p>\n

That’s why PHGG can go into drinks and foods without changing their taste, texture or colour, according to that same review. One thing to know: the review comes from the research lab of a company that makes PHGG.<\/p>\n

A review of its clinical nutrition uses<\/a> describes PHGG as a water-soluble fibre with many uses in clinical nutrition, thin enough to go into tube-feeding formulas and drinks.<\/p>\n

What is resistant dextrin?<\/h2>\n

Resistant dextrin, also sold as resistant maltodextrin, is a soluble fibre made from starch. It’s called “resistant” because your small intestine can’t fully digest it, so most of it travels on to your large intestine, where gut bacteria ferment it.<\/p>\n

It counts as real fibre. The US Food and Drug Administration lists “Resistant maltodextrin\/dextrin”<\/a> among the fibres it intends to add to its dietary fibre definition.<\/p>\n

In daily life, resistant dextrin is the fibre you don’t notice: it dissolves, doesn’t gel, and your drink still tastes like your drink. For amounts, read what resistant dextrin is and how much is too much<\/a>.<\/p>\n

Which one makes more gas?<\/h2>\n

This is the question that decides whether you stick with a fibre or give up.<\/p>\n

Any fibre your gut bacteria ferment makes some gas. What matters is how much, and how fast. When researchers fermented the two fibres side by side in the lab, a wheat-based resistant dextrin made significantly less gas than PHGG<\/a> at 12 and 24 hours. PHGG fermented faster. A second lab test<\/a> found the same wheat-based dextrin made the least gas of three fibres, and noted that the rate of gas production may affect how well people tolerate a fibre.<\/p>\n

Two caveats. These were lab tests, not people. And resistant dextrin made from wheat isn’t the same product as one made from corn. Both tests also share a co-author from a consumer-health company, so weigh them the way you’d weigh the PHGG review above. Treat them as a strong clue, not a promise. In the first test, though, both fibres showed prebiotic effects, so choosing the gentler one doesn’t mean giving that up.<\/p>\n

Whatever you take, pace matters as much as the fibre. HealthHub<\/a> warns that too much fibre too quickly can bring gas and bloating, and advises bringing it in gradually.<\/p>\n

Our verdict: resistant dextrin for daily use<\/h2>\n

If you want a prebiotic fibre you’ll still be taking next month, choose resistant dextrin.<\/p>\n

It doesn’t gel or change the taste of your drink, and in side-by-side lab tests a wheat-based resistant dextrin fermented more slowly and made less gas than PHGG. Those tests used a wheat dextrin, not Prebio’s corn dextrin, so the part we can promise you is the easy part: tear a sachet, stir, and get on with your day.<\/p>\n

In Singapore, the resistant dextrin we’d point you to is our own: ADVAGEN Prebio<\/a>.<\/p>\n
