Love this - it actually works! I've been using Dual Defence for a couple of months now and it's definitely worked for me. I bought it when I started sneezing and felt a cold coming on and it stopped it straight away. Since then I've been using it every day to prevent getting ill and haven't had a single cold yet - even though I've been surrounded by ill people at work and spend a lot of time on trains & planes. 100% recommend!

Brilliant product I use this every day, more than once when i get first signs of sniffles or cold coming on, and more than often it absolutely wipes away all the symptoms and i am feeling great again! Will use as part of my daily routine throughout winter.
