I take 5000 IU a day for three years and I rarely get sick and the few times I did catch something, it was very mild and maybe lasted a day..
I swear by the stuff...
Ditto
I’m so hesitant to rely on anecdotal date, but my doctor also put me on 5,000 IU a day (previously, I had taken no supplements), and I’ve gone from 2-3 colds a year, that lasted two weeks with nagging symptoms, to 1 cold in the last 3 years, where I felt bad for 1 day, and all symptoms gone after 3 days. So I’m onboard with vitamin D.
My vitamin D count was so low my doc wrote a prescription for 50,000 IU per week. At first it was a pharmacy pill to get me back to normal but now I take 3,000 IU / day and that seems to be maintaining my numbers.
Since I have started this I have not gotten sick either.
