HelloPharmacist Scorecard of Slendesta Potato Protein Extract 15 mg by Swanson Best Weight-Control Formulas

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: potato protein extract at 15 mg per capsule. Potato protein is derived from potato tubers and is marketed as a weight-control agent.

The capsule also contains gelatin, microcrystalline cellulose, magnesium stearate, purified water, and titanium dioxide as inactive ingredients.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Long-lasting appetite control.
  • We looked for evidence on: Appetite suppression, Weight management, Satiety, Food cravings.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The data we hold shows potato protein extract is rated possibly ineffective for colorectal cancer prevention, heart attack prevention, stroke prevention, and reducing overall mortality. These are the key health claims studied so far, and the evidence hasn't supported them.

If you're considering this product for weight control, we don't have effectiveness ratings on file for that specific use.

The evidence, ingredient by ingredient Potato

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.

Cooked whole potatoes are safe as food, and this extract is generally well tolerated when taken as directed. However, the safety data raises concerns about green, sprouted, or raw potatoes—they contain natural toxins called glycoalkaloids that can cause sweating, headache, flushing, nausea, vomiting, and diarrhea.

In severe cases, these toxins can cause paralysis and respiratory problems; importantly, cooking does not destroy them. For pregnancy and breastfeeding, cooked potato as food is fine, but medicinal use of potato juice or extracts isn't well studied in either situation.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or breastfeeding.

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 — Potato.
  • The most serious interaction on file is rated Moderate.
  • For scale: 7 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, check whether you take any thrombolytic drugs (clot-busting medications) or succinylcholine (a muscle relaxant used during anesthesia). Both have documented moderate interactions with potato extract.

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.

Slendesta Potato Protein Extract is one to flag with your doctor or pharmacist before starting—especially if you take blood clot–busting medications or are scheduled for surgery. The evidence doesn't support its use for cancer, heart attack, or stroke prevention.

If you're taking any medications, check them against the interaction tool on this page first.

Potato Protein extract2 drug types · 7 drugs

Succinylcholine

In humans, consuming potatoes prior to preoperative fasting prolongs the duration of the succinylcholine-induced neuromuscular block and slows recovery from anesthesia. This interaction is possibly related to inhibition of the butyrylcholinesterase enzyme by potato glycoalkaloids.

Likelihood Probable Evidence B
Thrombolytic Drugs

Theoretically, concomitant use of potato may enhance the effects of thrombolytic drugs. A carboxypeptidase inhibitor isolated from potato tubers may have inhibitory effects on thrombin-activatable thrombolysis inhibitor, and thereby enhance the activity of thrombolytic agents.

Slendesta Potato Protein Extract 15 mg by Swanson Best Weight-Control Formulas: Common Questions

Does Slendesta Potato Protein Extract 15 mg by Swanson Best Weight-Control Formulas interact with any medications?
Yes. Based on its ingredients, Slendesta Potato Protein Extract 15 mg has a known interaction with 7 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Slendesta Potato Protein Extract 15 mg 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.
Can I take this if I'm having surgery?
Not without talking to your surgical team first. Potato extract can prolong the effects of succinylcholine, a common anesthesia medication, and slow your recovery. Let your doctor and anesthesiologist know you're taking it well before any procedure.
Is this safe to take while pregnant or breastfeeding?
Cooked potato as food is fine in both situations, but this concentrated extract hasn't been well studied. Talk with your doctor or pharmacist about the risks and benefits before using it while pregnant or nursing.
What are the side effects of potato extract?
Whole, unblemished, ripe potatoes haven't been linked to side effects. However, potato juice has caused heartburn, bloating, diarrhea, and increased mucus in some people. Green or sprouted potatoes contain toxins that can cause sweating, headache, flushing, nausea, vomiting, and diarrhea.
Does this actually help with weight control?
The data we hold doesn't include effectiveness ratings for weight control. The extract is rated possibly ineffective for heart attack, stroke, cancer, and overall mortality based on available evidence.
Why do I need to avoid green or sprouted potatoes?
They contain glycoalkaloid toxins that affect your nervous system and can cause serious symptoms like paralysis and breathing problems in severe cases. Cooking doesn't destroy these toxins, so damaged or green potatoes should be avoided entirely.
