I bought this for my daughter previously and it helped her quite a bit as she does have a poor immune system, combine that with her being a nurse she is around ailments all the time. She failed to tell me she was out and she got very sick again just with a common cold. I purchased it again and told her to STAY on them. she has been healthy since.
