I bought these to boost our immune system in preparation for traveling including a 21 night transpacific cruise and 3 long airplane flights. My husband and I started taking 2 a day two weeks before leaving and all 30 days we were away. SO many people on the cruise were coughing and sneezing. We did not get sick at all!! Will definitely buy these again!!
