If you look at the Japanese study they found that more is better. They used 1TBSP apple cider vinegar/day for their high dose. The Greek study also used 1TBSP before eating. That is probably where I would start especially before a higher carb meal but managing the amount of food and the number of #carbs that you are eating is the biggest part of the #Diabetes picture. Apple cider vinegar is a good adjunct option.
