HelloPharmacist Scorecard of Sweet 'n Natural Pure Stevia by Superior Source

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.

This powder contains one active ingredient: stevia leaf extract, a sweetener derived from the stevia plant. Stevia is a zero-calorie alternative to sugar.

There are no other inactive 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 for stevia's effectiveness isn't established in the data we hold. It has been studied for blood sugar control, blood pressure, and weight management, but the research is too preliminary or inconsistent to make a reliable claim about whether it works for any of those 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 sweeteners at typical food amounts are generally well tolerated. The most common minor side effects — bloating, dizziness, headache, muscle pain, nausea, and numbness — tend to resolve within the first week.

Allergic reactions are rare. However, stevia in supplement doses hasn't been studied as thoroughly as food-grade amounts, so caution is warranted at higher intakes.

Pregnant or breastfeeding women should talk with their doctor or pharmacist before using this product, as safety data for those situations isn't on file.

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.

Check before taking this product if you use lithium (a moderate interaction concern), blood pressure medication, or diabetes medication. No interactions are documented for the inactive 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.

If you don't take lithium, blood pressure medication, or diabetes medication, this stevia powder is generally well tolerated as a sugar substitute. If you do take any of those medications — especially lithium — check with your doctor or pharmacist first.

Most people tolerate stevia without side effects, though some may experience temporary bloating or headache.

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.

Sweet 'n Natural Pure Stevia by Superior Source: Common Questions

Does Sweet 'n Natural Pure Stevia by Superior Source interact with any medications?
Yes. Based on its ingredients, Sweet 'n Natural Pure 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?
Sweet 'n Natural Pure Stevia contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Does stevia actually work for blood sugar or weight loss?
The evidence isn't solid enough yet for us to say it does. Studies have looked at stevia for blood sugar and weight, but the results are too early or mixed to claim it reliably works for either purpose.
What side effects might I notice?
Most common are bloating, dizziness, headache, muscle aches, nausea, and numbness. These tend to fade after about a week. Allergic reactions are rare. If side effects don't improve or worsen, stop and talk to your doctor.
Is stevia safe at normal sweetener amounts?
Purified stevia at typical food amounts is generally recognized as safe. Higher supplement doses haven't been studied as well, so the data recommends caution if you're using larger quantities.
Can I use this if I'm pregnant or breastfeeding?
Safety data for pregnancy and breastfeeding isn't on file. Talk with your doctor or pharmacist to weigh the risks and benefits for your situation.
Why does this interact with so many medications?
It doesn't — the 259-medication count reflects the total across all drugs in those three categories (lithium, blood pressure meds, and diabetes meds), not stevia interacting with each one individually. The actual concerns are with those three drug types.
