The science
How it works
Psyllium is a soluble fiber that forms a gel in water. It slows gastric emptying, binds bile acids (forcing the liver to pull cholesterol from blood), and is fermented by colonic bacteria to produce butyrate.
Getting it right

Dose guidance
Start with 5 g/day and work up to 10–15 g split across meals. Drink plenty of water — essential to avoid obstruction.
Best time to take
Before meals lowers post-meal glucose most. Evening works for bowel regularity.

Common questions
FAQ
Psyllium vs other fibers?
Psyllium is the most-studied for cholesterol and stool normalization. Inulin is better for feeding gut bugs but causes more gas.
Will it affect my meds?
Can reduce absorption of meds taken at the same time. Separate by 2 hours.
Keto-friendly?
Yes — psyllium is almost entirely fiber, minimal digestible carbs, and very filling.
