Dr Christopher makes really good health products and I’m sure this is helping lung health when taking daily. However if I’m being honest, I really don’t feel much of a difference when taking this. I know it’s a daily supplement which is why I’m not going to give it a super bad review. It is made to help overall health and certainly does not hurt to take. I just personally don’t like to take anything if I feel fine. If I am having a bad breathing day from my asthma, I expect it to help in a quicker amount of time, but this doesn’t seem to really impact very quickly. More of a long term health supplement, still not bad at all to have.
