Question: is it safe to drink apple cider vinegar at night?
Answer: Drinking apple cider vinegar before meals or right before bedtime may benefit your blood sugar levels the most. For example, one study in people with type 2 diabetes found that taking 2 tablespoons (30 ml) of apple cider vinegar at bedtime for 2 days reduced fasting blood sugar levels by up to 6% ( 7 ).
