HelloPharmacist Scorecard of Psyllium Husks Powder Berry by The Vitamin Shoppe
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This powder contains 3 active ingredients: soluble fiber (the bulk-forming laxative), psyllium husks powder (the fiber source itself), and stevia extract (a non-calorie sweetener). The soluble fiber works by absorbing water in your digestive tract, which thickens the stool and helps move it along.
You'll also find rice flour, gelatin, and magnesium stearate as inactive ingredients — the binders, fillers, and capsule materials that hold the formula together.
Does it work?
Strong evidence
The effectiveness data we hold doesn't establish whether stevia extract alone works for diabetes, high blood pressure, or weight loss. Some small clinical trials hint that stevia might lower blood sugar or blood pressure, but other trials didn't find those effects, and the overall evidence is considered insufficient to rate it for these uses.
The soluble fiber and psyllium husks powder are well-established for digestive health, but that evidence isn't detailed in the facts on file for this specific product.
How safe is it?
Well-documented data
Purified stevia in the amounts found in foods is generally well tolerated and recognized as safe. At higher supplement doses — like those in this product — the safety data is sparse, so use caution.
The most common side effects in trials were abdominal bloating, dizziness, headache, muscle aches, nausea, and numbness; most of these minor effects cleared up after the first week. Rare allergic reactions have been reported.
We have no pregnancy or lactation data on file for any ingredient in this product. If you're pregnant or breastfeeding, talk with your doctor or pharmacist about whether this product is right for you.
Meds to double-check
Moderate interaction found
Before you take this product, double-check with your doctor or pharmacist if you're on lithium (a Moderate interaction risk), blood pressure medications, or diabetes drugs (both Minor interaction risks). We could not check soluble fiber or psyllium husks powder for interactions, so confirmation of your full medication list is important.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is a soluble fiber supplement sweetened with stevia. If you take lithium, blood pressure pills, or diabetes medications, you'll want to check with your own doctor or pharmacist before adding it — stevia may theoretically interact with all three.
Most people tolerate it well, though some experience minor bloating, dizziness, or headache early on. Your healthcare provider can help you weigh whether it's a fit for your situation.

Psyllium Husks Powder Berry by The Vitamin Shoppe Drug Interactions
HelloPharmacist Interaction Report
Psyllium Husks Powder Berry by The Vitamin Shoppe interacts with medications through its stevia extract content.
The most serious concern is with lithium (a mood stabilizer), where stevia may theoretically slow your body's clearance of the drug and raise its levels to unsafe ranges — a Moderate severity interaction. Stevia extract also carries Minor interactions with blood pressure medications and diabetes drugs, where it might theoretically increase the blood-pressure-lowering effect or raise the risk of low blood sugar (hypoglycemia).
Read the full breakdown — every affected drug type, severity by severity
Although the evidence from clinical trials is mixed — some studies suggest stevia lowers blood pressure or blood sugar, while others don't — the theoretical risk remains. Altogether, these interactions span 259 individual medications.
We could not check two of the three active ingredients — soluble fiber and psyllium husks powder — because we hold no interaction data for them. Before you start this product, use the medication checker below to confirm your exact prescriptions, especially if you take lithium, blood pressure medications, or diabetes drugs.

For each ingredient in Psyllium Husks Powder Berry with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Dietary Fiber
Carbamazepine (Tegretol)
Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.
Lithium
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.
Metformin (Glucophage)
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
Olanzapine (Zyprexa)
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.
Digoxin (Lanoxin)
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.
Ethinyl Estradiol
Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.
Oral Drugs
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.
Stevia extract
Lithium
Theoretically, stevia might decrease clearance and increase levels of lithium.
Animal research suggests that stevia extracts might have diuretic activity. Theoretically, increased reabsorption of lithium along with sodium might reduce excretion and increase levels of lithium.
Antidiabetes Drugs
Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal. However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment.
Antihypertensive Drugs
Theoretically, combining stevia or stevia constituents with antihypertensive agents might increase the risk of hypotension.
Stevia extract and stevioside might lower blood pressure in patients with hypertension. However, other clinical research suggests that stevioside does not significantly lower blood pressure in patients with hypertension.
