HelloPharmacist Scorecard of Standardized Goji Berry by Nature's Way

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: Lycium (goji) berry extract and lycium berry fruit juice powder. Both forms come from the same plant and appear in clinical research on goji's effects.

The capsules also contain inactive ingredients—a plant-based capsule shell, silica, cellulose, and magnesium stearate—that help hold and deliver the active compounds.

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: antioxidant and immune support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Cardiovascular disease (CVD), Diabetes, Dry eye, Eye health, Anti-aging — and 1 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), Diabetes, Dry eye.

The evidence for goji isn't established in our data. The product facts list several uses—sunburn protection, heart health, blood pressure, weight, and quality of life—but every one is rated as having insufficient reliable evidence to draw firm conclusions.

If you're considering goji for one of these reasons, talk with your pharmacist or doctor about what the current research actually supports.

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 berries are generally well tolerated as a food, but concentrated supplement forms have less safety data behind them. Rare cases of liver inflammation (hepatitis and autoimmune hepatitis) and allergic reactions—ranging from itching and swelling of the mouth and throat to anaphylaxis—have been reported with goji.

During pregnancy, avoid medicinal amounts because safety data is limited and traditional reports suggest uterine effects. While breastfeeding, there isn't enough reliable data on supplement use, so caution is advised—talk with your doctor or pharmacist about whether it's right for you.

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.

Check with your pharmacist before taking this if you're on warfarin or another blood thinner (Major risk). Also double-check if you take drugs for heart rhythm (like flecainide), diabetes, or blood pressure control, or any medication metabolized by your liver's CYP2D6, CYP2C19, CYP2C9, or CYP3A4 enzymes (Moderate risks).

No interactions are documented for the ingredients we could check beyond those listed here, but absence of documented interactions is not proof that none exist.

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 warfarin or other blood thinners, don't start this without checking with your pharmacist first. Anyone on medications that your liver processes should double-check before adding goji.

If you have a history of allergic reactions to goji or related plants, steer clear. Otherwise, talk through any concerns with your pharmacist—they can help you weigh the unknowns.

Lycium (Goji) Berry extract8 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.

Standardized Goji Berry by Nature's Way: Common Questions

Does Standardized Goji Berry by Nature's Way interact with any medications?
Yes. Based on its ingredients, Standardized Goji Berry 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?
Standardized Goji Berry contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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?
The safety data advises against medicinal amounts during pregnancy due to limited data and traditional reports of uterine effects. Talk with your doctor or pharmacist about your specific situation before taking this product.
What is goji berry supposed to do?
The product facts list several potential uses—protecting against sunburn, supporting heart health, managing blood pressure and weight, and improving quality of life. However, the evidence for any of these isn't established in our data, so we can't say goji reliably does any of them.
Has anyone had side effects from goji?
Rare cases of liver inflammation and allergic reactions have been reported, including facial swelling, throat itching, and in severe cases, anaphylaxis. Most people tolerate goji well as a food, but concentrated supplements have less safety data.
Is there enough data on this while breastfeeding?
No—there isn't enough reliable data on supplement use while breastfeeding. Caution is advised, so talk with your doctor or pharmacist to decide whether it's safe for you and your baby.
Does goji affect how my liver processes drugs?
Yes. Lab studies show goji can slow down several liver enzymes that break down medications. This is one reason you need to check your exact drugs with a pharmacist before starting, especially if you take warfarin, diabetes drugs, or heart medications.
