HelloPharmacist Scorecard of Stevia Extract (90 % Steviosides) 250 mg by TerraVita Premium Collection

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 product contains one active ingredient: stevia extract standardized to 90% steviosides, a compound that comes from the stevia plant and is used as a sweetener. The capsule also contains gelatin and water as inactive ingredients to hold and deliver the extract.

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.

We don't have reliable evidence that stevia extract works for diabetes control, blood pressure, or weight loss. The research so far is preliminary and inconclusive — some studies suggest a benefit, others don't find one.

If you're considering it for any of these reasons, the data isn't established enough to say whether it'll help 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 food amounts is generally recognized as safe, but stevia supplements at higher doses aren't well studied, so caution is warranted. Most people tolerate it well — common minor side effects like bloating, dizziness, headache, muscle aches, nausea, and numbness usually go away after the first week.

Allergic reactions are rare but possible. There isn't enough safety data on file to say whether stevia supplement doses are safe during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice.

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, check with your pharmacist before starting — stevia may raise lithium levels. You should also confirm it's okay if you're on blood pressure or diabetes medications, since stevia might intensify their effects.

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.

Stevia extract is generally well tolerated in supplement form, but the evidence that it actually works for diabetes, blood pressure, or weight loss isn't there yet. The main reason to be cautious is if you take lithium or medications for blood pressure or diabetes — those need a closer look with your own doctor or pharmacist before you add this.

Stevia 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.

There isn't enough data on file to say either way for supplement doses. Talk with your doctor or pharmacist about whether it's right for you in those situations.
Is there anything other than stevia in the capsule?
Just gelatin and water as inactive ingredients to make the capsule. The active ingredient is the stevia extract itself.
