These are one of the best things I've ever purchased. I started taking these as soon as I started to notice any kind of cold symptoms and absolutely swear by them. I make sure to always have these on hand when traveling and STOCK UP at the beginning of cold and flu season. I cannot recommend them enough!
Boiron ColdCalm Tablets for Cold Symptoms - 120 Count
I love these! I start taking them at the beginning of cold and flu season, while I'm traveling, or just anytime I feel like I might be fighting something off or am going to be around large groups of people. I swear they boost my immune system like no other! They're a little pricey but oh so very worth it in my opinion!
