I used to have horrible sinus infections, that caused fever, runny nose, headache, nausea and lost work days.  Since I have been taking Shaklee's NutriFeron a long with Shaklee's Alfalfa Complex, I have not had a sinus infection, no colds and no flu since the end of 2005!  To say that I am pleased with the results is an understatement.  See below why Shaklee's NutriFeron works like nothing else in the marketplace.  Use the link here to watch a video on NutriFeron and then this one to purchase your own bottle of Shaklee's NutriFeron® (100% Money Back Guarantee).  Feel the Shaklee difference!   Elise
