HelloPharmacist Scorecard of Apple Pectin 300 mg by Swanson Premium Brand

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: apple pectin at 300 mg per capsule. Pectin is a type of soluble fiber found naturally in apples and other fruits that your digestive system uses to help lower cholesterol and may help manage blood sugar.

The capsule also contains inactive ingredients: rice flour, dextrose, gelatin, sodium citrate, and calcium laurate — these are fillers and binders that hold the supplement together.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Pectin's overall clinical evidence instead.

Moderate

Some clinical evidence supports Pectin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Natural Medicines).

Apple pectin is possibly effective for high cholesterol (hypercholesterolemia). The evidence isn't established for managing blood sugar problems (impaired glucose tolerance or prediabetes) or for reducing harm from radiation exposure — we simply don't have enough reliable data on those uses.

The evidence, ingredient by ingredient Pectin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pectin from food and typical supplement doses is generally well tolerated for most people. The most common side effects are mild — gas, loose stools, diarrhea, and mild cramping.

Allergic reactions are rare but possible, including in one reported case anaphylaxis in a child with oral allergy syndrome. There isn't enough data on concentrated pectin supplements in pregnancy or breastfeeding, so talk with your doctor or pharmacist before using this product if you're pregnant or nursing.

Dietary amounts of pectin are fine, but supplement safety hasn't been well studied in these situations.

Side effects, ingredient by ingredient Pectin

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Pectin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 23 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start, double-check this product against any digoxin (heart medications), lovastatin or other cholesterol drugs, and tetracycline or other antibiotics — pectin may reduce how well they work. Use the medication checker on this page with your exact medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Apple pectin may help with cholesterol if that's your goal, but it's most important to check it against any heart, cholesterol, or antibiotic medications you take — pectin can reduce how well some of these work. If you're pregnant, nursing, or have a history of food allergies, talk with your pharmacist first.

Apple Pectin3 drug types · 23 drugs

Digoxin (Lanoxin)

Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.
A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62%. It is unclear if these effects are due to pectin, kaolin, or the combination.

Likelihood Possible Evidence B
Lovastatin (Mevacor)

Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.
Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.
A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34%. It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.

Apple Pectin 300 mg by Swanson Premium Brand: Common Questions

Does Apple Pectin 300 mg by Swanson Premium Brand interact with any medications?
Yes. Based on its ingredients, Apple Pectin 300 mg has a known interaction with 23 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Apple Pectin 300 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will apple pectin help my cholesterol?
Apple pectin is possibly effective for high cholesterol based on the data we have. It's not a substitute for prescription medications, but it may help as part of your overall approach — talk with your doctor about whether it makes sense for you.
What side effects might I notice?
Most people tolerate pectin well. You might notice gas, loose stools, mild diarrhea, or mild cramping — these are the most common effects. Allergic reactions are rare but can happen in sensitive individuals.
Is it safe to take while I'm pregnant or breastfeeding?
Pectin from food is fine, but concentrated supplement amounts haven't been well studied in pregnancy or breastfeeding. There isn't enough data to know either way, so talk with your doctor or pharmacist for personalized advice.
What is apple pectin, and why is it in supplements?
Pectin is a natural soluble fiber from apples and other fruits. Your body uses it to help manage cholesterol and may help with blood sugar control. Supplement makers extract and concentrate it because you'd need to eat a lot of apples to get the same amount.
Can I take this if I'm allergic to apples?
If you have an oral allergy syndrome with apples or citrus, be cautious — one case report described anaphylaxis in a child with this history after taking a pectin supplement. Talk with your pharmacist or doctor before using this product.
