No Benefit1 study · 0 supporting · 1 against
How it was tested: In people with a slow-emptying stomach, vinegar slowed it further — the opposite of what you would want.
The acid may actually slow an already-sluggish stomach further, rather than get things moving.
Dose: 30 ml
Tested as: 30 ml apple cider vinegar in 200 ml water daily for 2 weeks, tested specifically in people with type 1 diabetes and diagnosed diabetic gastroparesis (delayed stomach emptying)
Apple Cider Vinegar for High Blood Pressure
Not verified1 study · 0 supporting · 0 against
Why it gets suggested: Its acetic acid is proposed to improve how blood vessels work. Not established in people.
Dose: 15–30 ml
Tested as: 15–30 ml vinegar daily for 8–12 weeks (pooled trials included apple cider vinegar and other vinegar types, not exclusively ACV)
Why we could not verify it: We read the research behind this and none of it concluded that it works for this. That is a finding about the papers, not a verdict that it does nothing.
