Why thousands choose PHGG for IBS

Feeds Your Good Bacteria

PHGG is a true prebiotic — it selectively feeds beneficial strains like Bifidobacteria and Lactobacilli, increasing their abundance and helping to support a healthier gut microbiome.

IBS-Safe & Low FODMAP Certified

Unlike many prebiotics, PHGG is certified low FODMAP by FODMAP Friendly — which means it's specifically safe for people with IBS or sensitive digestion.

No Dramas.

PHGG ferments slowly and gently, which is why it is much less likely to cause the gas and bloating that other fibres are notorious for. Your gut adjusts easily.
As Easy as It Gets

One scoop. Any drink.
Feel the difference.

1

Scoop

Add 1 level scoop (6g) into water, coffee, juice, yoghurt — anything you're already having.

2

Dissolve

Stir for a few seconds — it's completely tasteless, colourless, and won't change the texture of your drink.

3

Feel the Difference

Most customers notice real improvement within 14–28 days. Less bloating, better regularity, happier gut.

Full benefits

Most fibre supplements can make things worse.

You've tried pills, potions, and endless 'gut health' products. You ended up bloated, gassy, and uncomfortable. That's because most fibres ferment too fast — overwhelming your gut and triggering the exact symptoms you were trying to fix.

PHGG is different. It ferments slowly and gently, working with your gut microbiome — not against it. Tasteless, odourless, and kind enough for even the most sensitive tummies.

No More Bloating

Slow fermentation means dramatically less gas and bloating compared to other fibres like inulin or oligofructose.

Feed Your Good Bacteria

Acts as a prebiotic, growing beneficial strains like Bifidobacteria and Lactobacilli.

Works Both Ways

Whether you're constipated or loose — PHGG helps regulate and normalise bowel movements.

IBS-Safe & Certified

One of the only prebiotic fibres certified low FODMAP — safe even on a strict low FODMAP diet.
The Formula

One ingredient.

Perfectly chosen.

No fillers, no blends, no mystery ingredients. Just 100% Sunfiber® PHGG — one of the world's most studied soluble prebiotic fibres.
