They are small but they pack a punch when it comes to immunity. That is the soul reason I tried them and the results were well worth every single penny. I never go to the doctors for colds, sore throats, or illnesses any more after years of ongoing sickness in the winter months. I can literally throw away all my medicines because I have the only one that works now "DANACTIVE". It truly, truly boost the immunity. You can come in contact with a room of sick people, kiss a sick person and for some odd reason remain free of their sickness!!!!!! I am so happy I found this product and get the opportunity to share my thoughts.
