HelloPharmacist Scorecard of Clear 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.

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.

Clear Extract NuStevia is a single-ingredient liquid sweetener: NuStevia extract. The inactive ingredients are water, organic alcohol, vegetable glycerin, and natural flavors — these are the carriers and flavor additives that give the product its form and taste, not active components.

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 for stevia extract isn't established in our data. We hold ratings for diabetes, high blood pressure, and weight loss, but all three show insufficient reliable evidence to rate — meaning the science so far isn't solid enough to call it effective for those uses.

If you're thinking of this product to help manage a health condition, talk it over with your doctor about whether the current research supports it for you.

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 typical food amounts is generally recognized as safe. However, this is a supplement dose in liquid form, and high-dose supplements lack solid safety data, so use caution.

The most common side effects are mild — abdominal bloating, dizziness, headache, muscle aches, nausea, and numbness — and most seem to fade after the first week. Allergic reactions are rare but possible.

The safety profile in pregnancy and lactation isn't on file for stevia, so if you're pregnant or breastfeeding, talk with your doctor or pharmacist about whether this product is right for you.

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 — 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 start this product, double-check with your doctor or pharmacist if you take lithium — stevia might raise its levels in your body. You should also confirm it's okay if you're on blood pressure medications or diabetes drugs, since stevia could theoretically increase the effect of both.

No interactions are documented for the inactive ingredients we hold data on.

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 liquid stevia sweetener that's generally well tolerated in typical amounts, though high-dose supplement safety data is thin. It does interact with lithium (Moderate risk), blood pressure medications, and diabetes drugs (both Minor), so check your exact medications with your doctor or pharmacist before starting it.

If you take none of those drug types and want a stevia sweetener, it's worth a conversation with your healthcare provider about your individual needs.

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.

Clear Extract NuStevia by NuNaturals: Common Questions

Does Clear Extract NuStevia by NuNaturals interact with any medications?
Yes. Based on its ingredients, Clear 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?
Clear 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.
Is stevia safe for people with diabetes?
The evidence isn't clear enough yet to say stevia helps manage diabetes. One small study showed a single dose reduced blood sugar spikes after a meal, but other research doesn't support that effect. More importantly, if you take diabetes medication, stevia might increase your risk of low blood sugar — so you'd want to talk with your doctor before using it.
What side effects might I notice?
The most common ones are mild: bloating, dizziness, headache, muscle aches, nausea, and numbness. Most of these fade after the first week. Allergic reactions are rare but possible. If side effects don't settle down or get worse, stop and check with your pharmacist.
Is this product safe during pregnancy?
We don't have safety data on file for stevia in pregnancy, so there isn't enough information to know either way. Talk with your doctor or pharmacist about whether it's right for you while you're pregnant or breastfeeding — they can weigh your individual situation.
Can I use this if I take blood pressure medication?
Theoretically, stevia might lower your blood pressure further, but clinical evidence is mixed on whether it actually does. Either way, you should check with your doctor or pharmacist before starting it, especially if your blood pressure is already well controlled.
What's the difference between this and regular stevia sweeteners?
This is a purified stevia extract in liquid form, which is generally recognized as safe in typical food amounts. The caution here is that supplement doses in general lack as much long-term safety data as food-use amounts, so use it as directed and talk with your pharmacist if you have concerns.
