Really BAD product - not sure it even contains DGL!
I have purchased NOW and Enzymatic Therapy DGL from amazon and amazon marketplace sellers in the past. Both of those brands work very well. Tried this brand recently and my wife and I both agree that it simply does not work. It does not smell at ALL like licorice when you open the bottle and tastes like chalk. I would highly recommend buying another brand - we had to throw most of the bottle out.
