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 powder contains 2 active ingredients: stevia leaf concentrate (the sweetener) and FOS, a type of soluble fiber that may support digestive health. There are no other inactive fillers or binders 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 data we hold doesn't establish reliable evidence that stevia works for diabetes, high blood pressure, or weight loss — the research is mixed or incomplete. If you're considering it for one of those reasons, that's something to talk through with your doctor or pharmacist, since the evidence isn't there yet to say whether it'll help.

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 well tolerated and recognized as safe. However, supplement doses (like in this powder) haven't been studied as thoroughly, so we'd advise caution with higher amounts.

When people do report side effects — usually mild ones like bloating, dizziness, headache, muscle aches, nausea, or numbness — they tend to go away after the first week. Allergic reactions are rare but possible.

The facts we have don't include pregnancy or breastfeeding safety data for this specific product, so talk with your doctor or pharmacist if you're pregnant or nursing.

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 you start, double-check this product with your doctor or pharmacist if you take lithium (a moderate interaction risk), or any blood pressure or diabetes medications (minor interaction risk). No interactions are documented for FOS, the second active ingredient, but we hold no data on it.

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.

This stevia sweetener is generally well tolerated at typical food doses, but supplement amounts aren't as well studied, so use it cautiously. If you take lithium, blood pressure medications, or diabetes drugs, you'll need to check with your doctor or pharmacist before using it — the stevia could affect how those work.

Otherwise, it's worth a trial if you're looking for a plant-based sweetener.

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.
