I have read, that apple cider vinegar helps lower glucose levels. If this is true, then what would be the correct dosage to take on a daily basis? My husband has type 2 diabetes, and takes metformin daily. I try my best to cook the right things that he needs to be eating, even though he complains he is still hungry...he's a farm boy! So I'm just wondering if the apple cider vinegar is something that will actually help.
Vinegar may indeed lower blood glucose levels, according to some studies. The acetic acid in vinegar (which is what gives vinegar its tanginess) is thought to block the action of certain enzymes that break down carbohydrate. As a result, some carbohydrate goes undigested and, therefore, has less effect on blood glucose levels. Different studies have had success with different amounts of vinegar, ranging from 2 teaspoons to 2 tablespoons per day. In one study, people who took 2 tablespoons of apple cider vinegar along with some cheese before bedtime had a 4 to 6 percent reduction in their fasting blood glucose readings. Of course, taking vinegar may not lead to the same reductions in blood glucose levels in everyone. Also, taking too much vinegar can lead to acid reflux, indigestion and even damage to the esophagus. If you have low potassium levels or osteoporosis, you should talk with your provider before taking vinegar. Your husband certainly could try taking 2 teaspoons of vinegar with a meal, perhaps as salad dressing or drizzled on some vegetables. However, a bigger question might be whether your husband’s diabetes treatment plan and his metformin dose is still the right dose, and what his overall meal and physical activity plan look like. I suggest that your husband meet with a dietitian to discuss his food intake and activity level, and if his blood glucose and A1C levels are not within his target, I suggest he talk with his healthcare provider about his medication and what, if any, changes might be needed. Also, your husband should let his provider know if he does start taking vinegar regularly.
