HelloPharmacist Scorecard of Goji by Bronson Laboratories

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
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: goji powder, the fruit of the goji plant, used traditionally for overall wellness. The capsule also holds several inactive ingredients—cellulose, magnesium stearate, and silicon dioxide—which are common fillers and binders.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Goji's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: complete anti-aging and antioxidant coverage.
  • We looked for evidence on: Age-related macular degeneration (AMD), Cardiovascular disease (CVD), Cognitive function, Diabetes, Dry eye, Quality of life — and 3 related terms.
  • The closest evidence on file: Goji is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Goji is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Cognitive function, Diabetes, Dry eye, and more.

The evidence we hold doesn't establish that goji is effective for the conditions studied, including sunburn, heart disease, high blood pressure, weight loss, and quality of life. All of these are rated insufficient reliable evidence to rate, meaning the data simply isn't strong enough to say whether it works.

The evidence, ingredient by ingredient Goji

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.

Goji is generally well tolerated as a food, but concentrated supplements (like this one) have less safety data behind them, so a little caution makes sense. A small number of people have reported allergic reactions after eating goji berries—symptoms have ranged from itching in the mouth and throat swelling to severe reactions like anaphylaxis.

One case of autoimmune liver inflammation and another of acute hepatitis have been reported with goji use, though the second case involved a combination product, so it's unclear whether goji was solely responsible. During pregnancy, avoid medicinal amounts of goji because safety data is limited and traditional medicine reports suggest possible effects on the uterus.

While breastfeeding, there isn't enough reliable data on supplement use to know either way—talk with your pharmacist or doctor for personalized advice.

Side effects, ingredient by ingredient Goji

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Goji.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,001 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 taking this product, double-check warfarin (blood thinners) and flecainide (heart rhythm drugs)—Major interactions are documented. Also verify antihypertensive drugs (blood pressure meds), antidiabetes drugs (blood sugar meds), and any CYP2C9, CYP2D6, CYP2C19, or CYP3A4 substrates, where Moderate interactions are possible.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

If you take a blood thinner like warfarin, heart rhythm drugs, blood pressure medications, or diabetes drugs, you'll want to check with us before adding goji. Even if you're on other prescriptions, run them through our interaction checker because goji may slow how your liver processes many common medications.

It's generally well tolerated as food, but concentrated supplements are less studied.

Goji Powder8 drug types · 1,000 drugs

Warfarin (Coumadin)

Goji can increase the effects of warfarin and possibly increase the risk of bleeding.
There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine. Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9).

Likelihood Probable Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.
Animal and in vitro research suggest that goji root bark has hypotensive effects. However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes. Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate. Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.
In vitro research shows that goji berry juice inhibits CYP2D6 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.
In vitro research shows that goji berry juice inhibits CYP3A4 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Flecainide (Tambocor)

Theoretically, goji berry might increase the levels and clinical effects of flecainide.
In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.
Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects. However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia.

Goji by Bronson Laboratories: Common Questions

Does Goji by Bronson Laboratories interact with any medications?
Yes. Based on its ingredients, Goji has a known interaction with 1,000 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Goji 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.
Is goji safe during pregnancy?
No. The safety data is limited, and traditional medicine reports possible effects on the uterus, so medicinal amounts are best avoided during pregnancy. If you're pregnant or planning to be, talk with your pharmacist or doctor.
Can I take this while breastfeeding?
There isn't enough reliable data on goji supplements during breastfeeding to know either way. Talk with your pharmacist or doctor about whether it's right for you.
What are the side effects?
Most people tolerate goji well. A small number have reported allergic reactions—itching in the mouth, throat swelling, or in rare cases anaphylaxis. Very rarely, liver inflammation has been reported, though it's sometimes unclear if goji alone was responsible.
Does goji actually work for anything?
The evidence we have doesn't establish that goji is effective for the conditions studied—including heart disease, high blood pressure, weight loss, or sunburn. The data simply isn't strong enough to say it works for these.
Why does this one ingredient interact with so many drugs?
Goji appears to slow down how your liver breaks down many different medications through multiple enzyme pathways. That means it can theoretically pile up levels of a huge range of drugs—almost 1,000 individual ones—even though most of these effects have only been seen in test tubes, not in people yet.
