PHGG vs Inulin: Which Fibre Causes Less Gas?
PHGG and inulin are soluble, fermentable fibres, but many people find PHGG gentler when first increasing fibre. Inulin often ferments faster and can produce more gas at larger doses. Compare grams per serving, introduce one change at a time, drink enough water and judge the fibre by your own tolerance.

If a greens powder contains fibre, it is usually one of two: partially hydrolysed guar gum, written PHGG, or chicory root inulin. Both are soluble. Both are fermented by gut bacteria. They are not the same to live with, and the difference shows up fastest in the first week.
| Practical comparison | PHGG | Inulin |
|---|---|---|
| Fermentation pattern | Often described as more gradual | Often ferments faster |
| Starting example | Introduce a smaller amount, then assess tolerance | Introduce a smaller amount, especially if gas is a concern |
| What to compare on labels | Actual fibre grams, not just ingredient order | Actual fibre grams, not just ingredient order |
What PHGG is
Guar gum comes from the guar bean, grown widely in Rajasthan and Gujarat. Raw guar gum is highly viscous, which is why it is used as a thickener in food. Partial hydrolysis breaks the chains down so the viscosity largely goes, leaving a soluble fibre that dissolves without turning a drink into gel.
The result is close to tasteless, mixes clear, and ferments slowly along the length of the colon rather than rapidly at the start of it.
What inulin is
Inulin is a fructan, most often extracted from chicory root. It is also soluble, faintly sweet, and cheap relative to most functional ingredients, which is part of why it appears so widely.
It ferments faster than PHGG. Fermentation produces gas. In a person not used to the load, or at a large dose introduced suddenly, that is felt as bloating.
PHGG vs inulin compared
| PHGG | Inulin | |
|---|---|---|
| Source | Guar bean | Chicory root |
| Taste | Neutral | Slightly sweet |
| Viscosity in water | Low | Low |
| Fermentation speed | Slower, more gradual | Faster |
| Gas at introduction | Generally less | More commonly reported |
| Relative cost | Higher | Lower |
Why blends often use both
Different bacteria ferment different substrates, and fermentation happening across more of the colon rather than all at the front is generally the goal in formulation. Using two fibres with different fermentation profiles covers more ground than doubling one.
The catch is the same one as everywhere else on a label. If both are inside a proprietary blend, you cannot tell whether it is mostly the cheaper one with a token amount of the other. Inulin is cheaper than PHGG, so the incentive runs one way.
Fibre in the first week
Most complaints about greens powders in the first few days are fibre complaints, and they are largely a dose problem rather than a product problem.
Going from very little added fibre to a full scoop overnight gives gut bacteria a sudden new supply. Gas follows. Starting at half a scoop for three or four days and drinking enough water alongside it usually settles things, because the population adjusts.
If symptoms are severe or persist, that is worth raising with a doctor rather than pushing through, and people with diagnosed gut conditions should ask before starting any fermentable fibre.
What to check on a fibre label
- Is the fibre named, or is it just listed as dietary fibre?
- Is the amount given per serving, or hidden in a blend total?
- If two fibres are listed, can you tell the split?
- Does the brand tell you to start at a lower dose, or leave you to find out?
The fibres in SWATVA Daily Greens
Daily Greens uses PHGG alongside chicory inulin, and both are named on the label rather than folded into a blend. The guides say plainly to start at half a scoop for the first few days, because the alternative is people quitting in week one over something avoidable. The full ingredient list is public.
The first batch is 55 pouches. Pre-ordering takes four minutes and nothing is charged.
PHGG and inulin: what people search, answered
PHGG benefits for constipation, IBS and bloating
Partially hydrolysed guar gum (PHGG) is a soluble fibre that dissolves clear and tasteless. Trials found it improved stool regularity in constipation and eased some symptoms in people with IBS, usually at 5 to 6 g a day. It ferments slowly, so it tends to cause less gas than other fibres. IBS needs a doctor's diagnosis; PHGG is a dietary fibre, not a treatment.
Inulin benefits and side effects
Inulin, mostly from chicory root, feeds bifidobacteria in the gut and adds to daily fibre. It ferments fast, so larger amounts introduced quickly cause gas and bloating. Start at 2 to 3 g a day and build up.
How much PHGG or inulin per day, and when?
PHGG: studies commonly used 5 to 6 g a day. Inulin: 5 to 10 g a day once tolerated. Any time of day works; morning keeps the habit easy. Drink extra water as you add fibre.
PHGG vs psyllium husk (isabgol)
Psyllium has the most research for stool softness and cholesterol but forms a thick gel and can cause gas. PHGG dissolves clear, is tasteless and tends to be gentler. Many people tolerate PHGG better day to day; psyllium is cheaper.
Inulin vs psyllium husk
Inulin is a prebiotic that feeds gut bacteria; psyllium mainly adds bulk and water to stool. They do different jobs and can be used together.
Prebiotic fibre in Indian food
Onions, garlic, bananas (slightly green), whole dals, oats, barley and cooled rice all carry prebiotic fibre. Most Indian adults still fall short of 25 to 40 g of fibre a day.
Get both fibres, plus a probiotic, in one glass
Daily Greens includes PHGG and chicory inulin, two prebiotic fibres that feed different gut bacteria, together with the spore probiotic Bacillus coagulans MTCC 5856, digestive enzymes, grass juice powders and a B12 and D premix. Start with half a scoop for the first week.

Common questions
Which is gentler, PHGG or inulin?
PHGG usually is. It ferments more slowly, so it tends to cause less gas when you start.
Does inulin cause gas?
It can, especially at larger amounts introduced quickly, because gut bacteria ferment it fast. Starting low helps.
Can you take PHGG every day?
Yes, it is used daily in studies; a 12-week trial used 6 g a day. Start at a lower amount if fibre is new to you.
Is PHGG good for IBS?
Trials found PHGG eased some IBS symptoms and improved regularity at about 5 to 6 g a day. IBS should be diagnosed and managed with a doctor.
Which fibre causes the least gas?
PHGG usually causes less gas than inulin or psyllium because it ferments slowly.
Can I take PHGG every day?
Yes, studies used it daily. Start with a smaller amount if fibre is new to you.
Is inulin good for constipation?
Inulin adds fibre and feeds gut bacteria; some studies found improved stool frequency. Build up slowly to avoid gas.
