Date now is 11/2022 and it’s cold and wet here in Texas. I started taking this last month before it got cold and I’m doing 75 hard running out side while it’s cold and wet, haven’t got one sneeze or cough yet. So seems to be doing the job. It’s one of those things that you won’t feel it work. You have to recognize that you susceptibility to sickness has gone down. I’ll continue to use for sure.
