HelloPharmacist Scorecard of EarthSweet Stevia With FOS 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 Jul 23, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (325 mg) without saying how much of each component you get.

This product has 2 active ingredients: stevia leaf concentrate (the sweetener) and FOS (fructooligosaccharides, a prebiotic fiber). There are no inactive ingredients listed for this powder.

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 we hold doesn't establish how well stevia works for blood sugar control, blood pressure, or weight. We've rated the data as insufficient for all three — meaning the studies available don't give us a clear answer yet.

If you're looking for stevia to help with any of these, that's something to discuss with your doctor or pharmacist.

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 and its purified forms are generally well tolerated. The most common side effects are mild — abdominal bloating, dizziness, headache, muscle pain, nausea, and numbness — and most tend to fade after the first week.

Serious allergic reactions are rare. One important note: purified stevia used as a food sweetener has a longer track record of safety, but stevia supplements (especially whole-leaf or high-dose versions like this powder) haven't been as thoroughly studied.

Use caution and don't exceed recommended amounts.

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.

Before taking this product, double-check with your doctor or pharmacist if you take lithium, blood pressure medications, or diabetes medications. Stevia's effect on these drugs is mostly theoretical but real enough to confirm your situation is okay.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're looking for a stevia-based sweetener without interactions, this could work. But if you take lithium, blood pressure medicine, or diabetes medication, you need to check with your doctor or pharmacist first — stevia may affect how these drugs work.

Any new supplement deserves a quick conversation with your healthcare provider, especially if you're on prescription meds.

Stevia leaf 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.

EarthSweet Stevia With FOS by Planetary Herbals: Common Questions

Does EarthSweet Stevia With FOS by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, EarthSweet Stevia With FOS 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?
EarthSweet Stevia With FOS 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.
Can I take this if I'm pregnant or breastfeeding?
We don't have safety data on file for stevia in pregnancy or lactation. Talk to your doctor or pharmacist — they can weigh the limited data with your personal health and give you guidance tailored to your situation.
What are the side effects?
Most common side effects are mild: bloating, dizziness, headache, muscle pain, nausea, and numbness. These usually go away after the first week. Serious allergic reactions are very rare.
Is this sweetener safe?
Purified stevia used as a food sweetener is generally recognized as safe. But this is a supplement powder at higher doses than typical sweetener amounts, so the safety data isn't as robust — use caution and stick to the recommended dose.
Does stevia actually help with blood sugar or weight loss?
The evidence we hold doesn't establish whether it works for blood sugar control, high blood pressure, or weight loss. We've rated all three as insufficient evidence to say.
What is FOS?
FOS (fructooligosaccharides) is a prebiotic fiber — a type of carbohydrate that feeds the good bacteria in your gut. We don't have interaction data on file for it.
