I take one of these every day when I'm in a pressure situation or during cold and flu season. I've used it for years and don't get the flu that other's get. I've read it increases T-cell production which helps the immune system so folks with immune disorders should check if it is right for them. It's also not something that should be taken every day forever, more like every two weeks or a couple of months if you just take one capsule a day.

this is medium strong dose. if u're sick, u can take two at first stance instead of one. and three times daily one pill a day if u're sick. if u're not sick, one pill a day is enough.
