HelloPharmacist Scorecard of Sure Stevia Extract by KAL

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 17, 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.

KAL Sure Stevia Extract is a single-ingredient product: stevia leaf extract, a natural sweetener derived from the stevia plant. This ingredient has a long history as a food sweetener.

The product contains no inactive fillers or binders — it's pure stevia extract powder.

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's effectiveness in managing diabetes, high blood pressure, or weight is insufficient. While some preliminary research suggests stevia extract might lower blood sugar after meals and affect blood pressure, other clinical studies show no significant effect.

We don't hold enough reliable data to rate whether it actually works for these purposes.

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 food amounts is generally well tolerated and recognized as safe. However, this is a supplement-dose powder, not a food amount, and high-dose supplements haven't been well studied — so use caution.

The most common minor side effects are abdominal bloating, dizziness, headache, muscle pain, nausea, and numbness; most resolve within the first week. Serious allergic reactions are rare.

There is a caution with whole-leaf stevia and high-dose supplements due to limited safety data. Pregnancy and lactation safety information is not on file for this ingredient.

Side effects, ingredient by ingredient Stevia

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.

If you take lithium, any blood pressure medication, or any diabetes drug, double-check with your doctor or pharmacist before using this product. Stevia may raise lithium levels and could lower blood pressure or blood sugar further.

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.

KAL Sure Stevia Extract is a natural sweetener, but it's not proven to lower blood sugar, blood pressure, or weight. If you take lithium, blood pressure medication, or diabetes drugs, talk with your doctor or pharmacist before starting — the product may affect how these work.

For healthy people with no medications, it's generally well tolerated, though long-term high-dose safety isn't established.

Stevia Leaf 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.

Sure Stevia Extract by KAL: Common Questions

Does Sure Stevia Extract by KAL interact with any medications?
Yes. Based on its ingredients, Sure Stevia Extract 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?
Sure Stevia Extract 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.
What are the side effects?
Most common are bloating, dizziness, headache, muscle pain, nausea, and numbness. These usually go away within a week. Allergic reactions are rare. The supplement is well tolerated overall, but high-dose safety data is limited.
Is stevia safe for blood pressure or diabetes?
The evidence isn't strong enough to say stevia actually works for either. Some research suggests it might affect blood sugar or blood pressure, but other studies show no real effect — so we can't reliably rate it for these uses.
Is this safe in pregnancy or while breastfeeding?
We don't have safety data for stevia supplement at this dose during pregnancy or lactation. Talk with your doctor or pharmacist about whether it's right for you.
Why is there a caution about whole-leaf stevia?
Purified stevia in food amounts is recognized as safe. But whole-leaf stevia and supplement doses haven't been studied enough to confirm long-term safety, so the caution is there out of an abundance of care.
Does this product contain any fillers?
No — it's stevia leaf extract powder with no inactive ingredients added.
