You need to take quite a bit more if your COVID-19 shows your O2 is poor (using an oximeter) or you have pneumonia.
It says you could take 600 mg a day as a preventative, but it's not needed, so keep it until you think you are infected.
Thank you! This is really helpful I have a bottle of this stuff I don’t remember why I got it but after reading this I’m sure happy I have it!
