CONCLUSIONS:
Among adults with a high baseline prevalence of vitamin D insufficiency, implementation of a test-and-treat approach to vitamin D replacement did not reduce risk of all-cause ARI or Covid-19.
- PaulHoule 5y agoGenerally when you hear Vitamin D the conclusion is "Move on, nothing more to see here folks". Vitamin D is associated with good things (like your team won the Superbowl) but taking Vitamin D doesn't seem to lead to good outcomes any more than taking Vitamin D will make your team win the Superbowl.

- GuB-42 5y agoFrom the beginning of the pandemic, it was 50/50, and it still is. Half of the studies say it has an effect, the other half says it isn't significant. The only thing that seems pretty much settled is that when it comes to covid (and many other things) vitamin D is useless for those who are not deficient, and taking massive doses is likely to do more harm than good. The uncertainty is whether reasonable supplementation to compensate for what is a common deficit during winter is effective or not against covid, both in term or infection and severity.
- jjtheblunt 5y agoI wonder if that's because vitamin d is a downstream effect of physical activity, which in sunlight increases vitamin d levels, and which strengthens bodies when they're fit enough to be strengthened?
