Psyllium Husk Dosage Chart
Psyllium husk is a soluble dietary fiber derived from the seeds of Plantago ovata. It absorbs water to form a gel, adding bulk to stool, lowering LDL cholesterol, and improving blood sugar control. It requires adequate water intake to work safely.

Safety Cautions
- ALWAYS take with at least 8 oz of water — psyllium without water can cause esophageal or intestinal obstruction.
- Start with 1/4 to 1/2 the target dose and increase gradually over 1–2 weeks to reduce gas and bloating.
- May reduce absorption of certain medications — take medications at least 2 hours before or after psyllium.
- Rare psyllium allergy (including anaphylaxis) has been reported — discontinue if you develop rash, difficulty breathing.
- People with strictures, bowel obstructions, or swallowing difficulties should avoid.
Frequently Asked Questions
How much psyllium husk should I take per day?
For constipation, take 5–10 g (1–2 teaspoons of powder) up to 3 times daily, always with at least 8 ounces of water. For cholesterol reduction, 7–10 g per day in divided doses with meals is the studied dose. Start low (2.5–5 g/day) and increase gradually over 1–2 weeks to minimize bloating.
How much psyllium husk is in a teaspoon?
One teaspoon of psyllium husk powder is approximately 5 grams. Metamucil and similar products use the same measurement. Whole psyllium husks are slightly bulkier — 1 teaspoon may be closer to 3–4 g.
Can dogs take psyllium husk?
Yes. Psyllium husk is commonly used for constipation and diarrhea in dogs. The typical dose is 1/4 teaspoon per 10 lbs of body weight, mixed into food with adequate water. Always consult a veterinarian before starting.
