HelloPharmacist Scorecard of Sweet 'n Natural Stevia Leaf Extract 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 is a single-ingredient product: stevia leaf extract, a natural sweetener derived from the stevia plant. The powder form contains lactose as an inactive ingredient.

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: natural sweetener for low-sugar dietary needs.
  • We looked for evidence on: Diabetes, Hypertension, Obesity, Glucose tolerance, 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 Hypertension, Obesity.

The product facts don't establish reliable evidence that stevia works for diabetes, high blood pressure, or weight loss. Early research hints that stevia may affect blood sugar and blood pressure, but the data isn't strong or consistent enough to confirm it.

If you're considering this for any health purpose, the science just isn't there yet.

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 well tolerated and recognized as safe. However, this is a supplement-dose product, and high-dose supplements haven't been well studied — so caution is warranted.

The most common side effects are mild: bloating, dizziness, headache, muscle pain, nausea, and numbness; these tend to resolve after the first week. Rare allergic reactions have been reported.

Because safety data on whole-leaf and supplement doses is limited, talk with your doctor or pharmacist before starting if you have concerns.

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 using if you take lithium — stevia may raise lithium levels (Moderate severity). Also flag any blood pressure medications or diabetes drugs you're on; stevia may intensify their effects (Minor severity for both).

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.

This stevia extract is generally well tolerated in short-term use, but it does carry risks with lithium and minor interactions with blood pressure and diabetes medications. If you take any prescription drugs — especially lithium — check them against the tool on this page before you buy.

A conversation with your own pharmacist or doctor is the best way to know whether it's right for you.

Formulation

Zero calorie powder

More recent medical research has shown promise in treating obesity and hypertension. Stevia has a negligible effect on blood glucose, even enhancing glucose tolerance; therefore, it is attractive as a natural sweetener to diabetics and others on carbohydrate-controlled diets.

Sweet ‘n Natural is Calorie free, Saccharin free, Aspartame free, and Sucralose free.

FDA Statement of Identity

Dietary Supplement

Formula

Stevia is a genus of about 240 species of herbs and shrubs in the sunflower family (Asteraceae), native to subtropical and tropical regions from western North America to South America. The species Stevia rebaudiana, commonly known as sweetleaf or Sugarleaf, or simply stevia, is widely grown for its sweet leaves. As a sweetener and sugar substitute, stevia’s taste has a slower onset and longer duration than that of sugar.

With its extracts having up to 300 times the sweetness of sugar, stevia has garnered attention with the rise in demand for low-carbohydrate, low sugar food alternatives. In a few countries, it has been available as a sweetener for decades or centuries; for example; stevia is widely used as a sweetener in Japan where it has been available for decades.

Suggested/Recommended/Usage/Directions

Directions: As an herbal dietary supplement, take 1/3 teaspoon into food or stir into beverages.

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.
