Maybe there's something different about the capsules. All I know is that using pure juiced ginger has worked well for me. Of course I have also been sticking to a good diet, doing a mild colon cleanse, taking oils, probiotcs and emergen c. It all adds up. I take the ginger mixed with cucumber and Celery juice first thing in the morning following a cup of hot water and ACV, after meals and whenever I feel any acid coming on. Works a treat
