It doesn't say when they took the blood sample that was used. The issue being, if someone is ill they typically don't go outside. They also likely eat less. At some point vitals are going to tail off.

I'm not disputing the value of Vitamin D. But without details this could be a simple case of correlation.

Vitamin D always to remain in the body for months, so I think that's unlikely to cause a significant difference.

The opening paragraph says it studied ppl after one year of high dose Vitamin D. That doesn't really apply to most people.
