HelloPharmacist Scorecard of Pure Extract NuStevia by NuNaturals

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 Sep 3, 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: stevia extract (also called NuStevia extract), a zero-calorie sweetener derived from stevia plant leaves. It's sold as a liquid, with no inactive fillers or other ingredients listed.

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 Stevia product and its label doesn't state a use — see Stevia'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 we hold doesn't establish that stevia works reliably for blood sugar control, blood pressure, or weight loss. Studies are limited and results are mixed—some research suggests a single dose may lower blood glucose after a meal in people with type 2 diabetes, but other studies don't confirm a significant effect on blood pressure in people with high blood pressure.

For all three uses, the data is insufficient to rate it as effective.

The evidence, ingredient by ingredient Stevia

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.

Purified stevia in the amounts you'd use in food is generally well tolerated and recognized as safe. However, this product is a concentrated supplement extract, not a food amount, and high-dose supplements haven't been well studied—so use caution.

Side effects are usually mild and may include bloating, dizziness, headache, muscle pain, nausea, or numbness; most clear up after the first week. Allergic reactions are rare but possible.

Because safety data for supplement-level doses are limited, talk with your doctor or pharmacist before starting, especially if you're pregnant, nursing, or have kidney or heart concerns.

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 — Stevia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 259 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 with your doctor or pharmacist if you're on lithium (Moderate risk of raised levels), blood pressure medication, or diabetes medication (both Minor risk). No other drug interactions are documented for the ingredients we could check.

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.

NuStevia is a zero-calorie sweetener, but as a concentrated extract it hasn't been studied for long-term safety at supplement doses. If you take lithium, blood pressure medication, or diabetes medication, you'll need to check with your doctor or pharmacist before using this product—the interactions are documented and worth clarifying for your specific situation.

NuStevia extract3 drug types · 259 drugs

Lithium

Theoretically, stevia might decrease clearance and increase levels of lithium.
Animal research suggests that stevia extracts might have diuretic activity. Theoretically, increased reabsorption of lithium along with sodium might reduce excretion and increase levels of lithium.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal. However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining stevia or stevia constituents with antihypertensive agents might increase the risk of hypotension.
Stevia extract and stevioside might lower blood pressure in patients with hypertension. However, other clinical research suggests that stevioside does not significantly lower blood pressure in patients with hypertension.

Pure Extract NuStevia by NuNaturals: Common Questions

Does Pure Extract NuStevia by NuNaturals interact with any medications?
Yes. Based on its ingredients, Pure Extract NuStevia has a known interaction with 259 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pure Extract NuStevia 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 this stevia sweetener raise my blood sugar?
No—stevia itself has no calories and doesn't contain sugar. One study suggested a single dose might even lower blood glucose slightly in people with type 2 diabetes, but other research doesn't support a consistent effect. The evidence overall is too thin to say it reliably helps or hurts blood sugar control.
Is this safe to use every day?
Purified stevia in food amounts—the kind in diet sodas and sweetener packets—is recognized as safe for daily use. This product is a concentrated liquid extract, which hasn't been studied as thoroughly at high doses over time. Use caution with daily supplement doses and discuss your plan with your pharmacist or doctor.
Can I use this if I'm pregnant or breastfeeding?
The safety data on file for stevia supplement doses in pregnancy and lactation is incomplete—there isn't enough evidence to say whether it's safe or not. Talk with your doctor or pharmacist about whether it's right for you in these situations.
What side effects might I notice?
Most people tolerate it well. The most common mild side effects are bloating, dizziness, headache, muscle soreness, nausea, or numbness—and most of these tend to clear up after the first week. Allergic reactions are rare.
Why can't I just check my own medications online?
You absolutely can use the drug checker on this page—that's exactly what it's for. If you're on lithium especially, or on blood pressure or diabetes medication, run your specific drug names and doses through the tool, then talk with your pharmacist about the results.
