HelloPharmacist Scorecard of Stinging Nettle Extract Powder 1000 mg by BulkSupplements.com

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 powder contains one active ingredient: Stinging Nettle Root Extract at 1,000 mg per serving. The only other ingredient is dextrin, an inactive filler.

Stinging nettle has been used traditionally for joint and urinary health, and some clinical research suggests it may help lower blood sugar in people with diabetes. The extract concentrates the root, which animal studies suggest has mild diuretic (water-removing) properties.

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 Stinging Nettle's overall clinical evidence instead.

Moderate

Some clinical evidence supports Stinging Nettle 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: Diabetes — rated "Possibly Effective" (Natural Medicines).

The evidence is strongest for diabetes: stinging nettle is rated Possibly Effective for lowering blood glucose levels. For everything else on the label — hay fever, anemia, asthma, benign prostatic hyperplasia (enlarged prostate), and gingivitis — we don't have enough reliable evidence to rate how well it works.

That doesn't mean it doesn't work; it means more research is needed.

The evidence, ingredient by ingredient Stinging Nettle

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.

Stinging nettle is generally well tolerated when taken by mouth as directed, though constipation or diarrhea can occur in some people. There is one case report of liver injury in someone taking a multi-ingredient herbal tea that included stinging nettle, though it's unclear whether the nettle alone was responsible.

Stinging nettle is best avoided during pregnancy due to traditional concerns about effects on the uterus and lack of safety data. Safety during breastfeeding hasn't been established either, so talk with your doctor before using it if you're nursing.

If you touch fresh stinging nettle plant material directly, expect itching, rash, and stinging — these symptoms are usually temporary but can last hours.

Side effects, ingredient by ingredient Stinging Nettle

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 — Stinging Nettle.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 164 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, check with your pharmacist if you take warfarin or other blood thinners — stinging nettle's vitamin K content can reduce their effectiveness. Also double-check if you're on diabetes medications, diuretics (water pills), or lithium, as stinging nettle may add to their effects in ways that need monitoring or dose adjustment.

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.

Stinging nettle extract may be worth considering if you have diabetes and want to explore complementary approaches to blood sugar management — but check with your pharmacist first, especially if you take warfarin, diabetes meds, water pills, or lithium. It's not appropriate during pregnancy or breastfeeding.

Your doctor or pharmacist can tell you whether it's right for your situation.

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Stinging Nettle Extract Powder 1000 mg by BulkSupplements.com: Common Questions

Does Stinging Nettle Extract Powder 1000 mg by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Stinging Nettle Extract Powder 1000 mg has a known interaction with 164 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Stinging Nettle Extract Powder 1000 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 stinging nettle lower my blood sugar if I'm not diabetic?
Clinical research shows stinging nettle can decrease blood glucose levels in people with diabetes. We don't have data on whether it affects blood sugar in people without diabetes, so if you're not diabetic and you're curious, ask your doctor or pharmacist.
What are the most common side effects I might notice?
When taken by mouth, constipation and diarrhea are the most commonly reported side effects. Most people tolerate it well, though individual responses vary.
Is stinging nettle safe to take while I'm pregnant?
No — there isn't enough safety data, and traditional concerns about effects on the uterus mean it's best avoided during pregnancy. Talk with your doctor before using it if you're expecting or planning to become pregnant.
Can I breastfeed while taking this?
Safety during breastfeeding hasn't been established, so it's best to avoid it until you talk with your doctor. They can weigh the benefits and risks for your situation.
What is stinging nettle actually used for?
The evidence is strongest for diabetes — it's rated Possibly Effective for lowering blood sugar. For other conditions like hay fever, anemia, asthma, and enlarged prostate, there isn't enough reliable research yet to know how well it works.
Why is there a diuretic interaction with water pills?
Stinging nettle has its own mild diuretic properties — meaning it encourages your body to remove water. If you also take a diuretic medication, the two effects could add up and cause too much fluid loss. Your doctor may need to monitor or adjust your dose.
