I bought these on a wim, I was sick and dragged myself to the drug store in search of relief.
They did nothing for my current sickness, I don't believe I recovered quicker because I took them, and I don't believe they improved my immune system.

With that being said, I did understand that the intent was to take them prior to ward off sickness. So I kept them in my medicine cabinet and started to take them at the onset, just when I was starting to feel a tickle in my throat. Again, they did nothing for me, just like the time before.

Save your money, don't buy these, instead just buy regular echinacea, vitamin C, drink lots of fluids and eat chicken noodle soup, these will all work , if not better then Cold FX.

I think these pills are such a rip off. My husband seems to think they work but I don't think they work at all. They cost a fortune and they aren't effective.

Bought it, tried it, didn't work at all. Would never buy again. Vitamins are your best bet.
