Bests & Worsts Reviews from Amazon

COVID-19 was actually the best thing that has happened to me in five years. I had asthma until 1994 and started taking a lot of vitamins. I also take a lot of supplements. Five years ago I developed a cough like a heavy smoker. Three years ago I went to a pulmonologist who wanted to put me on an inhaler but I didn't want to use a steroid so I never used it. I never thought there would be a supplement to improve respiratory function but because of COVID-19, I thought I would see if I could find anything. I found quercetin and ordered this. It arrived the day before I got sick with COVID-19 in late March and I have not been coughing since. Quercetin is amazing. I take it twice a day and don't cough anymore. If I stop taking it I will start coughing again but I will stop coughing within five minutes of taking another pill. If it wasn't for COVID-19, I never would have looked for a supplement to improve respiratory function.
