What Is Psyllium Husk?
Psyllium husk is a soluble fiber derived from the seeds of the Plantago ovata plant. You get it as a fine powder or loose husks that absorb water and expand in your gut. Many dietary supplements, like Metamucil, feature psyllium for its high fiber content—providing about 5 grams of soluble fiber per tablespoon. Food manufacturers include psyllium in products such as breakfast cereals, baked goods, and nutritional bars to improve fiber intake.
You digest psyllium husk minimally, so it helps support regular bowel movements and manage blood sugar. Clinical studies, including those cited by nutritional experts such as Dr. Peter Attia, associate regular psyllium use with improved cholesterol levels and better glycemic control in people with type 2 diabetes. Mayo Clinic and NIH define psyllium as a primary bulking agent in dietary therapy for irritable bowel syndrome and constipation.

Why Peter Attia Recommends Psyllium Husk
Peter Attia recognizes psyllium husk as a core fiber supplement for metabolic and cardiovascular health optimization. He references data from randomized controlled trials to support its daily use.
Health Benefits Highlighted by Peter Attia
Attia links psyllium husk intake with improved lipid profile and digestive function. He cites studies demonstrating reductions in LDL cholesterol by 5%-10% with daily consumption, especially when taken as part of a diet low in saturated fat. He points to research showing psyllium’s positive effect on glycemic control in type 2 diabetes, noting lowered fasting blood glucose and stabilized postprandial spikes. He highlights increased stool consistency and frequency, relevant for people experiencing IBS or chronic constipation. Attia emphasizes its prebiotic effects, supporting beneficial gut microbiota and reducing inflammation risk.
Dosage and Usage Suggestions
Attia suggests starting with 1 teaspoon (about 2.5 grams) psyllium husk once daily and increasing by increments after several days, typically reaching 1-2 tablespoons per day (about 5-10 grams) for most adults. Mix psyllium husk with at least 8 ounces (240 ml) water to prevent clumping and support safe passage through the digestive tract. Consume it immediately after mixing, as psyllium thickens rapidly. Take psyllium separately from other supplements or medications by at least 1 hour to prevent impaired absorption. Attia recommends observing personal tolerance and adjusting frequency or volume to avoid bloating or gas.

Potential Risks and Considerations
Psyllium husk generally supports digestive and cardiovascular health, but specific risks and interactions exist for some users. Reviewing side effects, medication conflicts, and individual factors guides safe usage.
Interactions and Side Effects
Psyllium husk may affect how certain medications, including antidepressants (for example, sertraline), diabetes drugs (like metformin), and cholesterol-lowering agents (such as statins), are absorbed. Separate psyllium intake from medications or supplements by at least 1 hour to reduce interference, as emphasized by Dr. Peter Attia. Mild digestive issues, such as bloating, excess gas, or cramping, sometimes occur when you increase fiber intake rapidly or take larger doses. Rarely, severe allergic reactions or obstructions arise if you consume psyllium without enough water, according to Mayo Clinic guidance. Adjust dose slowly and maintain hydration to minimize discomfort. Consult your healthcare provider before use if you have bowel narrowing, esophageal disorders, or chronic GI diseases.

How to Incorporate Psyllium Husk Into Your Diet
Add psyllium husk to your diet by blending, stirring, or mixing it with water, beverages, or meals. Use a starting dose of 1 teaspoon (about 2.5 grams) daily, as highlighted by Dr. Peter Attia, then increase to 1-2 tablespoons (5-10 grams) per day, adjusting based on your personal tolerance. Dissolve psyllium in at least 8 ounces (240 ml) of liquid, as clumping may occur if the mixture stays too thick. Drink immediately after mixing to prevent thickening and reduce the risk of digestive discomfort.
List of ways to include psyllium husk in your meals:
- Mix into liquids: Stir psyllium into water, unsweetened almond milk, or smoothies to boost soluble fiber without changing flavor.
- Blend with foods: Sprinkle psyllium over yogurt, oatmeal, or cottage cheese to add texture and support gut health.
- Bake into recipes: Incorporate psyllium into homemade bread, muffins, or low-carb pancakes for increased fiber and better structure.
- Combine with shakes: Add psyllium to protein shakes or meal replacement drinks, especially after exercise for improved glycemic response.
Time psyllium intake away from medications or supplements by at least 1 hour, as recommended by research cited by Dr. Attia, to avoid possible absorption issues. Adjust the amount and frequency slowly to limit gas or bloating, especially if your previous fiber intake was low.
