This is the best product out here hands down no over the counter medicine will ever compare. When my husband, toddler and I were all sick with the common cold the “Taint No Flu” not only saved us! We were feeling better in a matter of 24 hours! We started taking it Saturday morning and by Sunday morning we felt better. It really does cut the duration and treats the symptoms of your cold. This is one thing I always keep in stock in my home I NEVER run out.
