I started using Armra at least 3 years ago and at the same time started working with young children and teens. Every time someone got a virus, it would go through their whole household, but we started noticing that I never caught any of the viruses even though I was in their faces, they were in my cars, etc. This alone was amazing bc I used to be the person that caught every bug that was going around. My husband was so impressed, he started taking it and had the same exact results. And the one time he had to go away for a couple of months and forgot his Armra, he caught his first cold in years. Now we both take it faithfully, every morning - and sometimes at night too. And with the individual packets, it’s perfect for traveling!!
