HelloPharmacist Scorecard of Juniper Berries 520 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: juniper berry, at 520 mg per capsule. The capsule itself is filled with inactive ingredients — gelatin, calcium palmitate, rice flour, and silica — which help hold the supplement together and have no therapeutic role.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Juniper product and its label doesn't state a use — see Juniper's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for juniper berry's effectiveness isn't established in our data. The product facts we hold show insufficient reliable evidence to rate it for GERD, rheumatoid arthritis, urinary tract infections, wound healing, kidney stones, and bronchitis — the conditions most commonly tied to it.

That doesn't mean it doesn't work; it means solid clinical trial data on those uses isn't available for us to review.

The evidence, ingredient by ingredient Juniper

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.

Short-term use of juniper at low doses is generally well tolerated, though a complete safety review hasn't been done. The main concern is kidney irritation with long-term use, so this shouldn't be taken continuously.

Topically, juniper can cause skin irritation, allergies, and (with sun exposure) burn-like blistering. Inhaled juniper pollen may cause respiratory allergies with repeated exposure.

Juniper is traditionally avoided in pregnancy because it may affect the uterus, so don't use it if you're pregnant. There isn't enough safety data to recommend it while breastfeeding either.

Side effects, ingredient by ingredient Juniper

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 — Juniper.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 162 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 take this product, double-check any diabetes medications you're on (risk of low blood sugar), diuretics (water pills), and lithium. No interactions are documented for other major medication types.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take diabetes medication, a diuretic, or lithium, check with us before starting juniper. Pregnant and breastfeeding people should skip it.

For anyone else, short-term use at normal doses is generally okay — just don't take it long-term, since it may irritate your kidneys.

Juniper Berries 520 mg by Swanson Premium Brand: Common Questions

Does Juniper Berries 520 mg by Swanson Premium Brand interact with any medications?
Yes. Based on its ingredients, Juniper Berries 520 mg has a known interaction with 162 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Juniper Berries 520 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.
Can I take this if I'm pregnant or breastfeeding?
No. Juniper is traditionally avoided during pregnancy because it may affect the uterus, so don't use it if you're pregnant. There also isn't enough safety information to recommend it while breastfeeding — talk with your pharmacist or doctor about what's right for you.
How long can I safely take juniper berries?
Short-term use is fine, but don't take it long-term. Medicinal doses can irritate your kidneys, so this supplement is meant for occasional use, not ongoing.
Will this actually work for my UTI or GERD or other condition?
We don't have reliable evidence that juniper works for those uses. The studies just aren't solid enough to say either way. Your doctor or pharmacist can help you figure out what might be more proven for your situation.
What's in this besides the juniper?
The capsule is made of gelatin and contains fillers like rice flour, silica, and calcium palmitate — all inactive ingredients that just hold the supplement together.
Can juniper cause side effects?
When you take it by mouth in low doses for short periods, it's generally well tolerated. If you apply it to your skin, though, it can cause irritation, allergies, and even burn-like blistering — especially if you're in the sun.
