HelloPharmacist Scorecard of Apple Cider Vinegar by Windmill Natural Vitamins

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 16, 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: apple cider vinegar in powder form, which delivers the same acetic acid and compounds found in liquid apple cider vinegar but in a capsule. The inactive ingredients are maltodextrin, gelatin, sorbitol, silica, and magnesium stearate — these are fillers and binders that make the capsule.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Apple Cider Vinegar's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Digestive health and weight management.
  • We looked for evidence on: Dyspepsia, Obesity, Appetite suppression, Postprandial glucose control.
  • The closest evidence on file: Apple Cider Vinegar is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).
  • Also on file: Apple Cider Vinegar is rated "Insufficient Reliable Evidence To Rate" for Obesity.

The evidence for apple cider vinegar is insufficient to rate its effectiveness for the uses on file: acne, athletic performance, cognitive function, dental plaque, depression, and atopic dermatitis (eczema). That means we don't have solid research showing it works for these purposes — not that it doesn't work, just that the data we hold doesn't establish it.

The evidence, ingredient by ingredient Apple Cider Vinegar

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.

In the amounts you'd get from food, apple cider vinegar is generally well tolerated. For short-term medicinal use in normal doses, it also seems well tolerated orally.

However, larger doses or long-term use raise concerns. One documented case involved someone taking 250 mL of liquid apple cider vinegar daily for 6 years and developed low potassium, high renin levels (a kidney-related marker), and osteoporosis (weak bones).

The safety data we have is limited for supplement-sized doses taken long-term, so large or unpasteurized amounts shouldn't be used without your doctor's approval. If you apply it to skin, there's a risk of chemical burns and irritation — even a single application has caused burns in reported cases.

Side effects, ingredient by ingredient Apple Cider Vinegar

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 — Apple Cider Vinegar.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; heart-rhythm medications.
  • For scale: 162 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 combining this with diuretic drugs (water pills), digoxin (Lanoxin), insulin, or oral diabetes medications. The most serious concerns are Moderate — low potassium risk with diuretics and digoxin, and possible blood sugar effects with insulin and diabetes drugs.

Even if your doses are small, these combinations need review beforehand.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Apple cider vinegar capsules may appeal to people curious about traditional uses, but the evidence for treating acne, brain function, or skin conditions isn't established yet. If you take water pills, heart medications like digoxin, or insulin, you'll need to talk with your doctor or pharmacist before starting this — the interaction risks are real.

Long-term use in larger doses carries safety concerns too. This is one to run by your own healthcare provider before you take it.

Apple Cider Vinegar, Powder4 drug types · 162 drugs

Digoxin (Lanoxin)

Theoretically, concomitant use of apple cider vinegar with digoxin might increase the risk of cardiac toxicity.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar could decrease potassium levels, increasing the risk of toxicity with digoxin.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of apple cider vinegar with diuretic drugs might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. There is some concern that people taking apple cider vinegar along with potassium depleting diuretics might have an increased risk for hypokalemia.

Likelihood Possible Evidence D
Insulin

Theoretically, concomitant use of apple cider vinegar with insulin might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar concomitantly with insulin might increase the risk of hypokalemia.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking apple cider vinegar with antidiabetes drugs might increase the risk of hypoglycemia.
Apple cider vinegar might reduce fasting and postprandial blood glucose levels and decrease gastric emptying in people with diabetes. However, not all research agrees. Theoretically, it might have additive effects on glucose levels when used with antidiabetes drugs.

Apple Cider Vinegar by Windmill Natural Vitamins: Common Questions

Does Apple Cider Vinegar by Windmill Natural Vitamins interact with any medications?
Yes. Based on its ingredients, Apple Cider Vinegar has a known interaction with 162 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Apple Cider Vinegar 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 apple cider vinegar help with acne or eczema?
The evidence we have isn't strong enough to say whether it works for acne, eczema, or the other uses listed. You'd want to talk with your doctor or dermatologist about proven options instead.
Is it safe to use apple cider vinegar long-term?
In food amounts, it's fine. But large doses or long-term supplement use haven't been well studied. One case reported serious problems — low potassium, weak bones, and kidney changes — after 6 years of daily use. If you're thinking of taking it regularly and in larger amounts, check with your doctor first.
What's in this product besides the apple cider vinegar powder?
The capsule contains inactive ingredients: maltodextrin, gelatin, sorbitol, silica, and magnesium stearate. These are fillers and binders to hold the capsule together.
Can I take this if I'm on a water pill?
Not without checking first. Apple cider vinegar may lower potassium levels, and diuretics do the same thing — together the risk is higher. Talk to your doctor or pharmacist before adding this to your regimen.
What about using it on my skin?
Topical use — applying it directly to skin — carries a risk of chemical burns and irritation, even from a single application. If you're thinking of putting it on your skin, talk to your doctor or dermatologist about safer options.
What happens if I take this with diabetes medication or insulin?
Apple cider vinegar might lower blood sugar on its own, so combined with insulin or oral diabetes drugs, you could have too-low blood sugar (hypoglycemia). Your doctor or pharmacist needs to review this combination and possibly adjust your doses before you start.
