Is it safe to take apple cider vinegar in type 2 diabetes?

Yes, but why? In limited amounts, but it won't help you in any way. Don't get your medical information from friends, tv or the internet. There are many important things you need to do to keep your diabetes in control, but vinegar isn't one of them.
Sure.. There is insufficient evidence, however, to say that it helps with type 2 diabetes. It's a pretty good digestive aid though, and might have an effect. Always use it diluted. Strait apple cider vinegar can damage your teeth.
