Yeah, you can get sick, but with your blood d at 60 you won’t unless it’s really infectious or you’re run down a little. My athlete son got hit with a stomach bug too.
I always wonder why docs never advise vit d. Not even for children who are constantly sick. It really helps.
My doctor is in a group that recommends Vit D and even sells it in 1500 unit gel caps over their counter at check out
I finally gave it a try last year, after contracting chest congestion that just kept hanging on. Started at 3,000 IU and will occasionally up it to as much as 6,000 if I’m feeling subpar. The congestion broke up, and the effect was comparable to Mucinex. Haven’t had as much as a head cold since, and I’ve always been one to catch whatever bug is going around.
It’s cheap, the apparent benefit is good and the downside appears to be limited to extremely high dosages, at a level I’ve never approached. I plan to continue taking 3,000 - 6,000 IU daily.
