Can you take apple cider vinegar with coffee?
No trial has tested apple cider vinegar and coffee taken together. The two share one practical overlap worth knowing: both are acidic, and vinegar's acid content is the reason capsule labels direct a full glass of water, whatever else is in the cup.
There's no published study testing apple cider vinegar and coffee taken together. The two share one practical overlap: both are acidic, and vinegar's acid content has been linked to tooth enamel wear and, in tablet form, esophageal irritation — reasons a vinegar capsule's label directs a full glass of water, coffee or not.
What hasn't been tested
No trial has measured whether coffee changes how apple cider vinegar behaves once swallowed, or whether vinegar changes how coffee is tolerated. The research on each exists separately — vinegar's acidity has been studied on its own, and caffeine's effects on the digestive tract have been studied on their own — but nobody has combined the two in a controlled study. Anything said about "stacking" apple cider vinegar and coffee is a guess dressed up as advice, not a documented interaction.
What's documented about vinegar's acidity
A lab study that exposed human tooth enamel directly to several vinegar varieties for up to eight hours found mineral loss that grew with contact time and varied by which vinegar was used. Separately, a case report of esophageal injury from a vinegar tablet prompted lab testing of eight commercial vinegar-tablet products, which found wide, inconsistent variation in pH, acid content and labeling. Neither study involved coffee — both are about what concentrated vinegar acid can do to tissue on direct or prolonged contact, in liquid or tablet form.
A capsule swallowed with water doesn't sit against tooth enamel the way sipping liquid vinegar does, which is a meaningful difference in exposure. It's still why the water instruction matters: a systematic review of apple vinegar's human and animal safety data rated the risk of side effects at typical recommended intakes as low, but flagged that most of what's documented comes from short, small studies.
Taking it alongside your morning coffee
Electric Tiger Apple Cider Vinegar Capsules provide 1,000 mg of organic apple cider vinegar powder per two-capsule serving, alongside inulin, DigeZyme and Lactobacillus acidophilus LA85 — as low as $12.95 a bottle on subscription. The label directs two capsules daily with 6–8 oz of water; it doesn't specify a time relative to coffee or any other beverage, and no research gives a reason to add one.
Questions people ask
Can you take apple cider vinegar with coffee?
There's no research against it and no research testing it — no study has looked at the two together. The practical guidance that exists is about vinegar's acidity generally: take a capsule with a full glass of water, as directed.
Does coffee cancel out apple cider vinegar?
No study supports that idea. There's no documented mechanism by which coffee would block or "cancel" anything about a vinegar capsule, and nothing has been tested to show otherwise.
Should you take apple cider vinegar before or after coffee?
No study has tested timing apple cider vinegar around coffee specifically, so there's no evidence-based recommendation to give. Follow the label's serving directions rather than a timing rule that hasn't been studied.
Can I put apple cider vinegar in my coffee?
Electric Tiger's product is a capsule, meant to be swallowed with water, not stirred into a drink. Mixing liquid vinegar into coffee is a different product and method than what's covered here, and it isn't something the research above speaks to.
