I’m thinking of flagging this since it seems to overweight the risk of high vitamin d vs the more common risk of low vitamin d?

I'm the one who wrote the article. I would actually argue that the risk of low Vitamin D has been overplayed. There are very alarmist articles out there about this epidemic of Vitamin D deficiency - which causes people to go out and buy supplements. But there is very little actual data showing that healthy people should take Vitamin D. This is where you get into the large human trials of Vitamin D supplementation, which I want to get into for part 3.

Thank you for writing these articles. Even more thanks for coming here and participating in the discussion.

It came across to me as a warning that we wouldn’t be so cavalier about any other hormone, so we shouldn’t be with Vitamin D either. In that context it’s fine.

Please don't, unless your expertise is comparable to that of the physician who wrote the article.

Your average HN reader has probably seen enough articles posted here about vitamin D deficiency that we are in fact the perfect audience to read about the dangers of taking too much of it.
