Taking psyllium husk every day is harmful to the health of healthy adults.

Is it true that taking psyllium husk every day is harmful to the health of healthy adults?

Partly. Evidence on whether daily psyllium harms healthy adults is mixed and partial: meta-analyses report metabolic benefits and weight gain rather than harm, while a single case report describes intestinal obstruction in a young man and a clinic page lists mostly minor side effects. No source directly assesses overall health harm in healthy adults.
