According to the internet, it is way higher, probably over 9000.
Edit because the comment might be to shallow for HN: I sympathize with the struggle against depression and, after first-hand experience, share the skepticism against the widespread prescription of antidepressants and the methods of evidence presented for it.
Very serious and important topic.
Regarding Vitamin D, I am also supplementing in the Winter, but I have not read the article, which says it has an estimated reading time > 10min. I use one 1000IE (0.025mg according to the package) tablet a day max.
I'll bookmark this discussion page to read TFA later maybe.
It’s important to take Vitamin D, as a fat soluble vitamin, with dietary fat during a meal. Something about bile production and absorption.
Also important to take it with Vitamin K.
Yes, I remember that and have Vitamin D+K combo tablets with calcium.
Seems like it would be best to increase time spent outdoors though.
There's likely significant individual variation in bioavailability. I would start with 2-5K/day, then measure and iterate.
