Did not work for me
When this arrived, the ice pack that was supposed to keep the package cold and the probiotics alive was already room temperature. It wasn't dry ice, just a regular ice gel pack that you would place in a cooler. I tried the powder for chronic sinusitis but it didn't work so well because I suspect most of the probiotics were dead. I switched back to kim chi, which worked really well for me before. The kim chi worked really well and overall much cheaper, so I will be sticking with kim chi going forward.
