My immunity support; in addition to eating clean and exercise, that is. TDL and I both work in medical offices and are around sick people a lot. This is difficult for me, as I am a germaphobe and I tend to get a bit paranoid when someone as much as coughs around me. Luckily, I work for a M.D. who practices functional medicine and I have cabinets full of supplements at my disposal. These are my two favorites for immunity support. I fully credit these two supplements and our diet for TDL and I not getting sick since returning from our honeymoon in November.
Whenever one of us gets coughed on (fun!) or feels like we may be getting sick, we take a couple dropper-fulls of ECH+ in a glass of water, twice a day. As far as the Mycotaki goes, we take 2-3 pills, 3 times a day. Of course, lots of sleep, good food, and several neti pots are also part of our regime. (And I guess I should mention: this is just what works for us. I am not a doctor, just someone obsessed with health). Salud!
