How it works
PHGG acts as a substrate for beneficial gut bacteria, promoting their growth. This fermentation process produces short-chain fatty acids (SCFAs) which nourish colonocytes and help maintain gut barrier function. It also helps regulate bowel consistency.
Who should take it
Adults looking to address bloating, indigestion, irregular bowel movements. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
