I didn't read the original article, but it appears to conclude that a 400 IU vitamin D supplement in the absence of a diagnosed deficiency is life shortening. I quoted from this link https://www.thisisinsider.com/evidence-that-taking-vitamin-d-and-calcium-is-a-waste-2019-4
"Researchers found that people in the study who took 10 micrograms of vitamin D supplements daily— but had no pre-existing vitamin D deficiencies — increased their overall risk for cancer and death."
"The potential harm of vitamin D supplement use among individuals without vitamin D deficiency need to be further evaluated," said Fang Fang Zhang, MD, a co-author of the study."
