HelloPharmacist Scorecard of Apple Cider Vinegar by Sundown Naturals

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. The tablet also includes inactive ingredients — dicalcium phosphate and vegetable cellulose — which are fillers and binders that help hold the tablet together.

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 Apple Cider Vinegar product and its label doesn't state a use — see Apple Cider Vinegar'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 on apple cider vinegar doesn't establish that it works for the claims often made about it. For acne, athletic performance, cognitive function, dental plaque, depression, and atopic dermatitis (eczema), the data available shows insufficient reliable evidence to rate whether it's effective.

If you're considering this product for a specific health goal, talk it over with your doctor or pharmacist about what the current evidence actually supports.

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 eat apple cider vinegar in food, it's well tolerated. When taken by mouth short-term for medicinal purposes, it also seems well tolerated.

However, there's a catch: long-term use in larger doses may not be safe. The main concern is low potassium (hypokalemia), which has been reported with chronic high-dose use — one documented case involved someone drinking 250 milliliters daily for six years, which also led to bone loss (osteoporosis) and elevated renin levels.

There is little safety data on supplement-dose amounts, so if you're considering regular use beyond food amounts, check with your doctor or pharmacist first. If you apply it to your skin, there's a risk of chemical burns and irritation.

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.

Before taking Sundown Naturals Apple Cider Vinegar, double-check if you take digoxin (Lanoxin) — a heart rhythm medication — since low potassium from the vinegar could increase the risk of toxicity. Also discuss it with your doctor or pharmacist if you're on diuretics (water pills), insulin, or other antidiabetes drugs, as the vinegar may lower potassium or blood sugar levels.

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.

This supplement is one to clear with your doctor or pharmacist before you start, especially if you take a heart medication like digoxin, a water pill (diuretic), insulin, or a diabetes drug. Food amounts are generally well tolerated, but the medicinal supplement form carries risks with long-term use — mainly low potassium and bone loss.

The evidence doesn't yet establish that it works for the common health claims made about it.

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 by Sundown Naturals: Common Questions

Does Apple Cider Vinegar by Sundown Naturals 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 this actually help with acne or other skin problems?
The evidence we have on apple cider vinegar for acne and other skin conditions like eczema is insufficient to say whether it works. If you're thinking about using it for these purposes, talk with your doctor or dermatologist about what's actually proven to help.
Is it safe to take long-term?
In food amounts, yes — it's well tolerated. But long-term use of supplement doses in larger amounts carries risks, mainly low potassium and bone loss, especially with daily high-dose use over years. There's also little safety data on regular supplement-dose use, so talk with your doctor or pharmacist if you're thinking about taking it regularly.
Can I use it topically on my skin?
Apple cider vinegar applied to skin may cause chemical burns and irritation, especially with repeated applications or on sensitive skin. There are documented cases of burns from topical use, so it's not recommended — check with your doctor or pharmacist for safer options.
Is it safe during pregnancy or while breastfeeding?
We don't hold safety data for apple cider vinegar in pregnancy or lactation. If you're pregnant or breastfeeding and want to use this supplement, talk with your doctor or pharmacist for personalized advice.
What's the difference between using apple cider vinegar in food and taking this supplement?
Food amounts are generally well tolerated. The supplement form means you're taking larger, more concentrated doses, and that's where the safety concerns — low potassium, bone loss — show up, especially with long-term daily use. Food amounts are likely fine, but large supplement doses need caution.
