From the Research
The recommended dose of Metamucil (psyllium husk) for adults is more than 10g per day, with a treatment duration of at least 4 weeks, as evidenced by the most recent and highest quality study 1. When taking Metamucil, it is essential to mix it with at least 8 ounces of water and drink an additional glass of water afterward to prevent the fiber from expanding in the throat or causing constipation.
- Start with a lower dose, such as 1 tablespoon or one packet mixed in 8 ounces of water, taken once daily, and gradually increase as needed to avoid gas and bloating.
- Take Metamucil 30 minutes before or 2 hours after other medications to prevent interference with absorption.
- For constipation, take it before bedtime; for diarrhea, take it with each meal; and for cholesterol management, take it before meals.
- Metamucil works by absorbing water in the intestines to form a gel-like mass that helps regulate bowel movements, adds bulk to stool, and can help lower cholesterol by binding to bile acids.
- Results typically appear within 12-72 hours of consistent use.
- If you have swallowing difficulties, intestinal blockages, or are pregnant, consult your doctor before using Metamucil, as advised by previous studies 2, 3, 4. The most recent study 1 provides the strongest evidence for the optimal dose and treatment duration of Metamucil, and its findings should be prioritized in clinical practice.
