PHGG fibre: benefits, tolerance and how it compares.

PHGG means partially hydrolysed guar gum. It is a soluble prebiotic fibre often used where a lighter, low-gel daily fibre is preferred.

PHGG means partially hydrolysed guar gum. It is a soluble prebiotic fibre often used where a lighter, low-gel daily fibre is preferred.

PHGG is not psyllium with a different name. It behaves differently in water, in texture, and in positioning.

Key takeaways

  • PHGG is soluble and prebiotic.
  • It is usually lighter in texture than psyllium.
  • It belongs in gentle prebiotic and tolerance-led conversations.

What PHGG is

Partially hydrolysed guar gum is made from guar gum that has been processed to reduce viscosity. The result is a soluble fibre that can be easier to use in light drink formats than strong gel-forming fibres.

PHGG compared with common fibres

Compared with Main difference
Psyllium PHGG is lighter and less gel forming
Acacia Both can sit in gentle prebiotic routines
Inulin PHGG is often chosen when slower tolerance build is desired
