Psyllium
Also known as: psyllium husk, ispaghula, blond plantain
Psyllium is the seed husk of Plantago ovata, rich in soluble gel-forming fibre. It swells in water, softens stools and slows the absorption of sugars and fats from a meal.
What it is used for
- Regular bowel movements in constipation – strong evidence
- Modest LDL cholesterol reduction – strong evidence from meta-analyses
- Lower post-meal blood glucose rise – moderate evidence
- Feeling of fullness – weak to moderate evidence
Forms and how they differ
whole husk
most common form, stir into water
powder (ground)
swells faster, easier to dose
capsules
convenient, but an effective dose needs several capsules and plenty of water
Pairs well with
Plenty of fluids, a varied diet with fruit and vegetables, probiotics.
Do not combine / separate
Take medicines and other supplements at least 2 hours apart, as fibre can reduce their absorption.
Watch out for
Take care with swallowing difficulties, narrowing of the oesophagus or bowel, and diabetes treated with medicines (it may lower blood glucose). In pregnancy, kidney or liver disease and when taking medicines, consult your doctor.
Safety
No EFSA tolerable upper level; do not exceed the label dose. Without enough water it can cause blockage; bloating is common at first.
Practical tip
Start with half a teaspoon a day and drink it immediately, before the mixture thickens.
