Taking psyllium safely
- Mix powder and granules with at least 8 ounces of liquid right before you take them, and drink at least 8 ounces of liquid with each dose. Psyllium needs the liquid to work and to prevent side effects.[1]
- Do not take digoxin, aspirin or nitrofurantoin within 3 hours of taking psyllium.[1]
- Tell your doctor if you have diabetes, heart disease, high blood pressure, kidney disease, rectal bleeding, an intestinal blockage or difficulty swallowing.[1]
- Call your doctor right away if you have difficulty breathing, stomach pain, difficulty swallowing, a skin rash, itching, nausea or vomiting after taking it.[1]
- Be careful not to breathe in the powder when you mix a dose, since it can cause allergic reactions when inhaled.[1]
What Psyllium Does
- Bulk-Forming Laxative – Psyllium absorbs liquid in the intestines, swells and forms a bulky stool that is easy to pass. It is used to treat constipation.[1]
- Forms – Psyllium comes as a powder, granules, capsule, liquid and wafer, and it is usually taken one to three times a day.[1]
- How Long – MedlinePlus says not to take psyllium for longer than 1 week unless your doctor tells you to.[1]
- Other Uses – Doctors may also prescribe psyllium for diarrhea or high cholesterol, so ask about the risks for your condition.[1]
What the FDA Allows on a Psyllium Label
- Heart Disease Claim – The FDA allows a health claim that diets low in saturated fat and cholesterol that include soluble fiber from psyllium husk may or might reduce the risk of heart disease.[2]
- Purity – To qualify, the psyllium husk must be at least 95 percent pure.[2]
- Amount – A psyllium food must supply at least 1.7 g of soluble fiber per serving to carry the claim.[2]
What to Check on a Psyllium Label
- Organic Seal – Look for the USDA Organic seal if you want a certified organic product.[3]
- Form – Whole husk and finely ground powder mix differently. The Healthworks powder is measured by the rounded teaspoon, and the Organic India powder is a whole husk powder.
- Size and Price – Divide the price by the ounces to compare, and note that one pick is a 2-pack of 12 oz canisters.
- Ingredient List – A plain psyllium product should list one ingredient. Check for added sweeteners or flavors.
What the Research Says
MedlinePlus describes psyllium as a bulk-forming laxative used to treat constipation, and says it may also be prescribed for diarrhea or high cholesterol.[1] The FDA allows a heart disease health claim for psyllium husk only when the food meets set purity and soluble fiber amounts and the claim uses the words may or might.[2]How We Chose These Products
