Hi,
My mom has had type 2 diabetes for years, taking glucophage on a regular basis. I am not familiar with DB Guard, but I actually did order a trial pack of balinsnow (The product is actually called Balins just so you know...) for her to try, since it looked different from all those generic natural "wonder" pills, and the guys at their website gave me and my mom all the information shee needed to be confident enough about trying it (of course she asked her doctor before).
She is really satisfied with it, and has been using in on a daily basis for over 2.5 months now, with a real decrease in her blood sugar levels. I am no diabetes expert but my mom told me both she and her doctor were truly taken by surprise with the results.
Hope this helps. Good luck!
