Does apple cider vinegar have potassium?

Apple cider vinegar does contain some potassium, but not much. By USDA FoodData Central figures, it runs about 73 mg per 100 g — roughly 11 mg in a typical tablespoon — a small fraction of the 2,600-3,400 mg most adults need in a day. It isn't a meaningful potassium source at any realistic serving.

What's actually in a serving

USDA figures put liquid apple cider vinegar's potassium content at about 73 mg per 100 g. Scaled down to a tablespoon (about 15 g), that works out to roughly 11 mg — for comparison, a medium banana provides around 400-450 mg. Our capsule form is 1,000 mg of dried apple cider vinegar powder per two-capsule serving; we don't have data converting that back to a liquid-equivalent potassium figure, so we're not going to state one, but there's no reason to expect it functions as a meaningful potassium source either.

How much potassium you actually need

The National Academies' 2019 revised dietary reference intakes set the adequate intake for potassium at 3,400 mg/day for men and 2,600 mg/day for women, mostly from food — fruits, vegetables, legumes and dairy are the larger contributors most people rely on. No tolerable upper intake level is set for potassium in healthy adults, because the kidneys clear the excess; people with reduced kidney function are the exception, and should get potassium guidance from a doctor rather than a general adult figure.

A documented case worth knowing about

A published case report described a patient who developed low blood potassium, elevated renin and osteoporosis after ingesting "large amounts" of cider vinegar over an extended period. That's the opposite of what a potassium source would cause, and it's a single case tied to sustained, heavy, long-term intake — not a typical-use finding, and not evidence that a normal serving lowers potassium. It's a reminder that vinegar's effects on the body aren't reducible to its printed nutrition-fact numbers, and that "more vinegar" isn't a potassium strategy in either direction.

What our label provides

Electric Tiger Apple Cider Vinegar Capsules provide 1,000 mg of organic apple cider vinegar powder per two-capsule serving, alongside inulin, a digestive enzyme blend and a probiotic strain — 30 servings a bottle, as low as $12.95 on subscription. We don't make a claim about this product's potassium content or its effect on blood potassium levels.

Questions people ask

Does apple cider vinegar have potassium?

Yes, a small amount — about 73 mg per 100 g by USDA figures, or roughly 11 mg per tablespoon. That's far short of a meaningful contribution to the 2,600-3,400 mg adults need daily.

Is apple cider vinegar a good source of potassium?

No. At the amounts people actually consume — a tablespoon of liquid, or a capsule serving — the potassium contribution is a small fraction of the daily target. Food sources like fruits, vegetables and legumes contribute far more.

Can apple cider vinegar cause low potassium?

A published case report linked years of heavy, sustained intake to low blood potassium in one patient, alongside osteoporosis. That's a documented case tied to sustained heavy use, not something established for typical amounts — if you take a diuretic or have a condition affecting potassium, see apple cider vinegar and medications: what to check and ask a doctor.
