Highly effective and a lot easier to contemplate is:900 units of vitamin D3 per pound of body weight- easiest with the 5000-unit itty bitty gelcaps from WalMart. I did that 15 years ago two days into a really nasty flu that everyone else was carrying for two to three weeks. I took them before I went to bed. When I rose 7 hours later the flu was gone. Daughter repeated that scene two years later and wife a couple of weeks after that. To prevent flu and colds, get a load of sunshine on your skin daily during the summer and take 5 or 10 thousands of D3 daily. Of those in my family and the widows at church that I started on this, all have been free of flu and colds and NO shots, even when half the city is sick.
So 180,000 units for 200lbs of body weight??
meh it’s more fun to lick a frog
