I’m a big believer in Vitamin D supplements beginning with this post I made way back in 2006:

I heard about taking supplemental vitamin D several years back on the “This week in Tech - Security Now” podcast, of all things. It’s cheap, natural, so I figured what the heck. I went from getting 3 or 4 colds per year to zero colds per year. I take a single 5,000 IU D-3 capsule each day along with other vitamin supplements.
You need to take Vitamin K2 with it. K2 puts calcium into bones where it belongs.
Thanks for mentioning D3.
I have a problem that the referenced article doesnt distinguish between D2 and D3, D3 long argued to be a better formulation, D2 used in milk.
Note that skin produces D3 when exposed to sunlight. The problem is that the skins D3 is not immediately bioavailable. And if you clean up every day then it is argued that youre washing off the D3 before it can hit target. So D3 supplement is said to be a good idea if you work in office and clean up every day.
Corrections, insights welcome.
5000 iu for me, too, since 2006 also. I started three miserable days into a flu that had many people hereabouts abed for 2-3 weeks. 8 hours later I was FINE. Wife did the same the following year.
