Apple Cider Vinegar and Blood Sugar: What You Should Know

Some small studies suggest vinegar taken with a carbohydrate-rich meal may modestly lower the blood sugar rise after eating, but the evidence is limited, and apple cider vinegar is not a treatment for diabetes and must never replace medicines or medical advice.
What the research suggests
Most of the studies are small and short. They tend to look at vinegar taken with or just before a meal, and some report a smaller blood sugar rise afterwards. Results vary, doses differ, and the people studied were often few. A 2025 review of trials in people with overweight or type 2 diabetes also described the evidence as inconclusive overall.

Why it might happen
One idea is that the acetic acid in vinegar slows how quickly the stomach empties, which may blunt a sharp rise in blood sugar. This is a hypothesis, and it also explains why people with slow stomach emptying should be cautious.
Important safety points
- Do not stop or change diabetes medicines because of vinegar.
- If you take insulin or tablets for diabetes, speak to your doctor first, since combining them could affect your blood sugar.
- People with slow stomach emptying (gastroparesis) should avoid it unless advised by a doctor.
- Monitor your blood sugar as your doctor advises.
If you are healthy and curious
Using vinegar in a salad dressing with a meal is a food habit, not a treatment. Pair it with what matters more: balanced meals, fibre, protein, movement and sleep.
