As a preschool teacher, I was having trouble being sick all the time. The past two school years I got every single cold, virus and stomach flu going, no matter the amount of disinfectant wipes and hand washes. When a colleague told me about this supplement, I ordered straight away, desperate to feel better and go to work on the daily. I have been taking these since February and HAVEN'T BEEN HOME ILL FOR A SINGLE DAY. I feel a lot more energetic and haven't caught any viruses, flu's or colds for 5 (!!) months. I will never be without these ever again. THANK YOU
