HelloPharmacist Scorecard of Stevia Liquid Concentrate by Planetary Herbals

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 liquid concentrate. Stevia is a plant-derived sweetener that's been used for centuries in South America.

The liquid form makes it easy to add to drinks or foods. The only other ingredient is purified water.

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 at treating diabetes, high blood pressure, or obesity is not yet established in the data we hold. Early research hints it might help with blood sugar and blood pressure, but the findings are mixed and not strong enough to draw firm conclusions.

Talk with your doctor if you're considering stevia to manage any health condition.

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.

Stevia is generally well tolerated when used in typical sweetener amounts. Most people who use it don't report side effects, and any minor effects — like headache, dizziness, muscle pain, nausea, bloating, or numbness — usually go away after the first week.

Rare allergic reactions are possible. One important caveat: purified stevia in food amounts looks safe, but whole-leaf stevia or high-dose supplements haven't been studied much, so use caution if you're considering larger amounts.

There isn't enough data on file to know whether stevia is safe during pregnancy or while breastfeeding — talk with your doctor or pharmacist for personalized advice.

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.

Before you start, double-check if you take lithium (Moderate risk of higher levels) or blood pressure medication (Minor risk of too-low pressure). Also mention any diabetes medication you use (Minor risk of low blood sugar).

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 is a plant sweetener that's generally well tolerated in typical amounts. If you take lithium, blood pressure medication, or diabetes medication, check with your pharmacist before adding it — the interactions are mostly theoretical but worth verifying with your exact drugs.

For other uses, the evidence just isn't strong yet.

Stevia leaf liquid concentrate3 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 Liquid Concentrate by Planetary Herbals: Common Questions

Does Stevia Liquid Concentrate by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, Stevia Liquid Concentrate 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 Liquid Concentrate 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.
Will stevia help me lose weight?
The evidence isn't established yet in our data. Some research explores stevia for weight management, but we don't have enough reliable evidence to say whether it works.
What side effects should I watch for?
Most common are headache, dizziness, muscle pain, nausea, bloating, and numbness — but these usually fade after the first week. Allergic reactions are rare. If side effects stick around, stop and talk to us or your doctor.
Is liquid stevia safer than powder or tablets?
Purified stevia in typical sweetener amounts is generally well tolerated in any form. High-dose supplements of whole-leaf stevia or concentrates haven't been well studied, so use caution with larger amounts regardless of the form.
Can I use stevia while pregnant or breastfeeding?
There isn't enough data on file to know either way. Talk with your doctor or pharmacist about whether stevia is right for you during pregnancy or breastfeeding — it's a personalized decision based on your situation.
Why do you mention 256 medications if this product only has one ingredient?
That number is the total of individual medications across all the interaction categories for stevia. The same drug can appear in multiple categories, so the real-world list of drugs that could interact is smaller — which is why checking your exact medications with our tool matters.
