Is it safe to take apple cider vinegar every day?

A 2020 systematic review of the safety literature found the risk of side effects from apple cider vinegar at recommended amounts appears low. That's a reassuring finding at typical, label-directed use — but no trial has followed daily intake for a year or longer, so "safe daily" really means "safe at the amounts and durations actually studied," not an open-ended guarantee.

What the review actually found — and its limits

The review searched four databases and identified 13 human studies and 12 animal studies meeting its criteria. Its conclusion on side effects, at recommended amounts and ways of taking it, was reassuring. Its conclusion on the evidence overall was that research quality across this literature is inadequate for definitive conclusions, and it called for larger, longer, lower-bias trials. The longest controlled human trial we've found testing daily vinegar intake against a placebo ran 12 weeks. Nothing in the published research follows daily use for a year or more, so "everyday, indefinitely" is a claim the evidence doesn't cover either way.

What our label directs

Two capsules a day, with 6-8 oz of water, providing 1,000 mg of organic apple cider vinegar powder per serving. That's our product's specific instruction, not a number research has identified as an optimal or maximum safe daily amount — no such number is established for a capsule or powder form.

Diluting the liquid form

If you're asking because you're taking or considering liquid vinegar rather than a capsule: diluting it in water before drinking is standard, common-sense advice for reducing direct contact between concentrated acid and your mouth, throat and teeth, rather than a dose backed by a specific clinical trial. Our product sidesteps this question by design — it's a powder inside a capsule, so there's no acid taste or dilution step, though the "with 6-8 oz of water" instruction still matters (see when is the best time to take apple cider vinegar for why).

What about pets?

This is a human dietary supplement, and we haven't reviewed dosing research for dogs or cats. If you're asking on behalf of a pet, a veterinarian is who to ask — not a label written for a human serving.

Is it safe to drink apple cider vinegar every day?

At recommended amounts, a systematic review found the side-effect risk appears low — for however the studies in that review defined "recommended," which varied by form and study. See apple cider vinegar side effects for the fuller documented picture, including some rarer effects reported at high, long-term intakes.

How do you consume apple cider vinegar daily?
