HelloPharmacist Scorecard of Stevia by Bronson Laboratories

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

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 leaf extract, a sweetener derived from the stevia plant. The extract is delivered in a liquid form using deionized water and vegetable glycerin as inactive ingredients.

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 Stevia's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: sweetening agent without calories or blood sugar effect.
  • We looked for evidence on: Diabetes, Obesity, Glycemic control, Weight management.
  • The closest evidence on file: Stevia is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Stevia is rated "Insufficient Reliable Evidence To Rate" for Obesity.

The evidence for stevia's effectiveness is not established in the data we hold. It's been studied for blood sugar control in type 2 diabetes, blood pressure, and weight management, but the available research is too limited or conflicting to rate how well it actually works for any of these uses.

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 — like you'd find in sweetened beverages — is generally recognized as safe. However, this product is a supplement at higher doses than food use, and high-dose supplement safety data is limited, so use caution.

Stevia and its active compounds are generally well tolerated when taken by mouth. Most people experience no side effects, but some report minor ones like headache, dizziness, numbness, muscle aches, nausea, or bloating — these usually resolve within the first week.

Allergic reactions are rare but possible. Pregnancy and lactation safety data for this ingredient isn't on file, so talk with your doctor or pharmacist before using it if you're pregnant or nursing.

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.

Check your exact medications before starting, especially if you take lithium — stevia may raise its levels. Also double-check any blood pressure medications or diabetes drugs you're on.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Stevia liquid is a plant-based sweetener supplement, though its effectiveness for any health condition isn't well established. If you take lithium for mood disorders, blood pressure medication, or diabetes medication, you should check with your pharmacist before starting — the interaction with lithium is the main concern.

Otherwise, side effects are generally mild and short-lived.

General Statements

Stevia is used where a sweetening agent is desired without the calories or blood sugar effect. Stevia is 100 times sweeter than sucrose at 10% sucrose concentration. Stevia has no calories. Stevia does not affect blood sugar (no glycemic index) and is safe for those with blood sugar swings, hypoglycemia, hyperglycemia and diabetes. It is added to beverages and other foods to taste. It is an extremely sweet herb, so it should be added slowly until the desired amount of sweetness is achieved. Stevia is safe for children.

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.

Stevia by Bronson Laboratories: Common Questions

Does Stevia by Bronson Laboratories interact with any medications?
Yes. Based on its ingredients, Stevia 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?
Stevia 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 to use while pregnant or breastfeeding?
We don't have safety data for stevia supplement use in pregnancy or breastfeeding. Talk with your doctor or pharmacist about whether it's okay for you — they can weigh your individual situation.
What side effects might I experience?
Most people tolerate stevia well. If side effects do happen — like headache, dizziness, muscle aches, nausea, or bloating — they typically fade after the first week. Allergic reactions are rare but possible.
Does stevia actually help with blood sugar or weight loss?
The research on stevia for diabetes, blood pressure, and weight management is too limited or mixed to say whether it actually works. It's studied for these uses, but we can't reliably rate its effectiveness.
Is this the same as stevia in food and drinks?
Not quite. Food-grade purified stevia sweeteners in typical amounts are recognized as safe. This supplement uses whole-leaf stevia extract at higher doses, and those doses aren't as well studied — that's why we recommend caution with supplement-level use.
Can I use this if I take blood pressure or diabetes medication?
Check with your pharmacist first. Stevia might add to the blood-pressure-lowering effect of antihypertensives or increase low blood sugar risk with diabetes drugs. Your pharmacist can review your exact prescriptions.
