What the evidence says

Around 10g/day psyllium modestly lowers LDL in mild-to-moderate hypercholesterolemia (Anderson 2000).

A 2023 dose-response meta-analysis confirmed soluble fiber supplements reduce LDL and total cholesterol.

Cochrane review found pooled reductions in LDL when fiber intake increases, though trials are often short-term.

⚠ Safety & contraindications

— GI effects: Start slowly, increase gradually. Drink plenty of water.

Frequently asked questions

How much psyllium should I take?

Studies typically use 5-10g per day, split into 2-3 doses with meals and water.

How long until I see results?

Most studies show LDL changes within 6-8 weeks of consistent daily use.

Can I get enough fiber from food alone?

Potentially, but most people fall short. Supplementation is a practical way to close the gap.
