How to read this entry

We classify this term as named ingredient in the vegetables and fibre category. The linked products supply the observation; they do not by themselves establish the ingredient’s nutritional effect.

Check the preparation and amount in the finished food. A botanical name on a label does not itself establish a clinical effect.

Evidence status

This is an ingredient index entry linked to product information. We have not completed an ingredient-specific research appraisal for this entry. A term’s presence in a product does not demonstrate a health outcome, nutritional adequacy or the effect of that product.

Arm psyllium-husk-food

Psyllium versus cellulose in healthy cats

Direct · cat. Nine healthy neutered adult cats.

Tested form: Food containing approximately 6% psyllium husk powder. Dose: Approximately 6% (Percentage of food). Duration: 10 days. Comparator: Approximately 6% cellulose food, always fed second after a four-day washout.

Measured finding: Mean daily bowel movements were 1.6 versus 1.1; mean stool scores were 3.2 versus 2.6. Median moisture was 72.9% versus 66.5%.

Limitations: Small sample, fixed treatment order, and short collection periods. Psyllium stools were softer than the study’s optimal score; constipation relief was not measured.

Arm gi_diet_psyllium_0_5_percent

Psyllium-containing diets for chronic constipation in cats

Multi ingredient · cat. Cats with chronic constipation; 49 enrolled and two excluded. Diet-switch analyses included 26 test and 30 control diet observations, not 56 independent cats.

Tested form: Psyllium husk incorporated into a complete gastrointestinal diet. Dose: 0.5% psyllium as fed (Percentage of the complete diet as fed; oral feeding). Duration: 6 months. Comparator: Complete gastrointestinal test diet containing 6% psyllium as fed.
