Psyllium husk side effects & safety

Low concern
  • Very safe; start low to avoid gas and bloating.
  • Take with plenty of water - too little fluid can cause choking or blockage.
  • Separate it from medications by a couple of hours, since fiber can slow their absorption.

Is Psyllium husk worth it?

The anti-hype supplement: low marketing, high evidence. A few grams before meals with lots of water is one of the best-value things in the cabinet.
