A 200 in man should take 180000 iu of D3 to combat flu and another 180000 a second day if flu still present?
Yes. That’s 36 5k gelcaps. They are tiny and I took 31 of them in one “bite.” They are easy. You do that if you already have flu or a cold. I had skated for a year because my flu bouts had always been very mild and seldom then that one year I was miserably sick and sore all over. My wife brought me the gelcaps and I took the 31 of them that was indicated. I was over it by evening. That round of flu laid most everyone else that got it out for 6-10 days. My wife had read about it and was using it for a few months already. I had been skeptical and had declined.
