I seem to have one cold illness after another since August last year all of which had left me feeling very drained, with no energy. I am trying the recommended pulse method with the Immune tablets following the one month on, one month off course during these winter months. I must say I do feel better after a few weeks on the Immune tablets and notice that my energy has increased. They are easy to take too as chewable tablets and taste good too. Would definitely recommend.
