I work as a Chropractic Assistant and our office uses Standard Process supplements. I also am fortunate to use SP products as part of my health routine. Immuplex is one of the supplements that I take daily. It helps with immune system and viral infections. This is a huge concern having little ones that often bring germs home from school all the time. I would recommend that anyone considering buying supplements look at Standard Process. They are quality products that you can trust. They are quality products that I trust for my health, my family and friends!!!
