Psyllium Husk (fiber)
A soluble, gel-forming fiber. One of the best-proven supplements: lowers LDL cholesterol and improves constipation, with decades of consistent trials.
What the science says
- Lowering LDL cholesterol Strong evidence
Meta-analyses of randomized trials show that ~10 g/day of psyllium lowers LDL cholesterol by roughly 5–10%, an effect recognized by regulators in approved heart-health claims.
- Relieving constipation Strong evidence
As a gel-forming bulk laxative, psyllium consistently improves stool frequency and consistency in chronic constipation, and is a first-line recommendation in clinical guidelines.
- Blood sugar and satiety Moderate evidence
Taken before meals, psyllium modestly improves post-meal glucose in people with type 2 diabetes and can increase satiety.
