HelloPharmacist Scorecard of Stevia Powder 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 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, a natural sweetener extracted from the stevia plant. Stevia Powder has no inactive filler 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 isn't established yet. Our data shows insufficient reliable evidence to rate it for blood sugar control in diabetes, blood pressure reduction in hypertension, or weight management.

While some preliminary research suggests stevia extract might lower blood glucose after meals in people with type 2 diabetes, other studies haven't confirmed a clear effect — so we can't yet say whether it works for these 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 in typical food amounts is generally well tolerated and recognized as safe. However, this product is a supplement-dose powder, not a food sweetener, and high-dose supplements lack solid safety data — so use caution.

Most minor side effects (bloating, dizziness, headache, muscle aches, nausea, numbness) tend to resolve after the first week. Allergic reactions are rare but possible.

Pregnancy and lactation safety data for stevia supplements isn't on file, so talk with your doctor or pharmacist about whether it's right for you during these times.

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 with your doctor or pharmacist before taking this product if you're on lithium — stevia may raise your blood levels to unsafe ranges. Also confirm it with blood pressure medications (risk of pressure dropping too low) and diabetes medications (theoretical risk of low blood sugar).

No other medication interactions are documented for the ingredient we reviewed.

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 Powder is generally well tolerated at supplement doses, but it's not a good fit if you take lithium, blood pressure medications, or diabetes drugs without checking first. If you're looking for a sweetener and don't take those medications, it's likely safe — but the evidence for blood sugar or blood pressure benefits is thin.

Have a conversation with your own doctor or pharmacist about whether it makes sense for your situation.

Stevia3 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 Powder by Planetary Herbals: Common Questions

Does Stevia Powder by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, Stevia Powder 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 Powder 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.
What exactly is stevia?
Stevia is a natural sweetener derived from the stevia plant. Purified stevia products are generally recognized as safe in typical food amounts, but high-dose supplements like this powder are less well studied.
Does stevia actually lower blood sugar or blood pressure?
The evidence isn't clear yet. Some preliminary research suggests stevia might lower blood glucose after meals in people with type 2 diabetes, and some studies show it may lower blood pressure — but other research found little effect. We don't have enough reliable evidence to say it works for either purpose.
What side effects might I notice?
Most common are bloating, dizziness, headache, muscle aches, nausea, and numbness. These are usually minor and tend to go away after the first week. Allergic reactions are rare.
Is this safe if I'm pregnant or nursing?
We don't have pregnancy or lactation safety data on file for stevia supplements. Talk with your doctor or pharmacist to decide what's right for you during pregnancy or while breastfeeding.
Can I use this if I'm on diabetes medication?
You should check with your own pharmacist or doctor first. Stevia might theoretically increase the risk of low blood sugar when combined with diabetes drugs — and while that risk is theoretical, it's worth confirming your specific medications won't interact.
