The Claim
Many people believe that taking psyllium husk will provide immediate relief from constipation, assuming it works like a laxative.
Origin
This misconception may arise from psyllium's high fiber content and its frequent recommendation for digestive health, leading to an overestimation of its speed of action.
What Science Says
Psyllium husk is effective in improving bowel regularity, but its effects are not immediate. Studies show that psyllium works by absorbing water and adding bulk to stool, which may take 1-3 days to have a noticeable effect on constipation relief. It is not a fast-acting solution like stimulant laxatives.
Verdict
Mostly False
