HelloPharmacist Scorecard of Apple Cider Vinegar 450 mg by NOW

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 capsule contains one active ingredient: 450 mg of apple cider vinegar powder. The remaining ingredients—maltodextrin, hypromellose, stearic acid, and silicon dioxide—are inactive fillers and capsule materials used to form and preserve the supplement.

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 on apple cider vinegar for the purposes listed—acne, athletic performance, cognitive function, dental plaque, depression, and atopic dermatitis (eczema)—is insufficient to establish a reliable rating. That means we don't yet have solid data to say whether it works for these uses.

If you're considering this supplement for a specific condition, talk it over with your doctor or pharmacist to see what the best option is for you.

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 food amounts, apple cider vinegar is generally well tolerated. When used orally for short-term medicinal purposes, it also appears to be well tolerated.

However, the safety data for large supplement doses and long-term use is limited, and long-term use in larger amounts may be unsafe. Rare serious adverse effects from long-term oral use have been reported, including low potassium (hypokalemia), elevated kidney hormones, and bone loss (osteoporosis)—effects seen in one person who took 250 mL daily for 6 years.

Topical use (applying it to skin) carries a risk of chemical burns and skin irritation. There is no safety data on file for pregnancy and breastfeeding, so talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.

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 you take this supplement, double-check with your doctor or pharmacist if you're on digoxin (Lanoxin), any diuretic or water pill, insulin, or any antidiabetes medication. All of these carry a documented risk of interaction with apple cider vinegar.

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.

Apple cider vinegar in food amounts is well tolerated, but supplement doses come with limited long-term safety data and potentially serious interactions—especially with heart, blood pressure, and diabetes medications. If you take digoxin, diuretics, insulin, or other antidiabetes drugs, check with your doctor or pharmacist before starting this product.

For everyone else, discuss it with your healthcare provider to make sure it's right for you.

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 450 mg by NOW: Common Questions

Does Apple Cider Vinegar 450 mg by NOW interact with any medications?
Yes. Based on its ingredients, Apple Cider Vinegar 450 mg 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 450 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 on a water pill or diuretic?
Not without checking first. Apple cider vinegar may lower potassium levels, and diuretics already do that—using them together could lead to dangerously low potassium. Talk with your doctor or pharmacist before combining them.
Does apple cider vinegar really help with acne or skin?
The evidence we have isn't solid enough to say it works for acne or other skin conditions. If you're thinking about using it for your skin, talk with your doctor first—and avoid applying undiluted vinegar directly to skin, as it can cause chemical burns.
Is it safe to take this long-term?
We don't have enough safety data on long-term use of supplement doses. One serious case of low potassium, elevated kidney hormones, and bone loss was reported after 6 years of very high daily amounts. Stick with the dose recommended on the label, and discuss long-term use with your doctor or pharmacist.
Can I take this if I have diabetes?
Apple cider vinegar may lower blood sugar, so if you're on an antidiabetes medication, combining them could increase the risk of low blood sugar. Check with your doctor or pharmacist before starting this supplement.
What are the inactive ingredients?
The capsule contains maltodextrin, hypromellose, stearic acid, and silicon dioxide—fillers and capsule materials. If you have allergies to any of these, check the label or ask your pharmacist.
