Daily morning and afternoon exposure to bright light might actually be more important to reducing depression than direct vitamin D supplementation. Low vitamin D might just be an indicator that you are not getting enough sunlight. Sunlight also affects melatonin and serotonin levels, and synchronizes your Circadian rhythm. Not sure why that article doesn't talk about Seasonal affective disorder (SAD), and how bright…

Anecdotally agree with this. I have vitamin D deficiency, was given 50,000 IU a week vitamin D to get it up. Never worked. Went to the beach one week and got blood tested again and my vitamin D levels climbed significantly. Now I make it a point to get outside and sunlight

A lot of modern "problems" can be solved this way. The term koyaanisqatsi comes to mind, life out of balance.

I am thinking the same, and in a midst of self experiment where I ensure I get a decent dose of just seeing the world in bright daylight. Week into it and my sleep feels pretty solid. Easy to avoid daylight when working indoors all day.

Came here to say this: VD may be it, or even indirectly a measure of 'not getting outside' enough. Even the sunlight may not be it, literally a walk in the woods might be providing the effect. Or rather 'spending too much time in our own minds' etc..

Bright, direct light seems to be a major component, which is not what most people think of being in the "woods." See:

> Overall findings were that there is a relationship between vitamin D and depression, though the directionality of this association remains unclear.

Vitamin D really seems to be a good example of correlation does not imply causation. I’m looking forward to when the Vitamin D hype ebbs off and when we know what Vitamin D actually helps with.

My first winter in NYC was very rough and I didn't understand why at first. I got a blood test at the doc and he said my vitamin D was very low. I committed to walking in the sun at least a half hour a day, weather permitting, and I never really had issues again. Part of the issue was I was spending a lot of time walking outside but not in sunlight due to the tall buildings. Just my anecdotal 2c

wildly speculating from an evolutionary perspective - it reasons that we'd evolve such that our moods are better in light - otherwise there would be another push to stagnate vs become exposed to more - such that evolution can do it's thing - evolution tends towards evolution after all -

I finally got a chance to move south and this was the first winter I didn't spend being weird and existential about everything. Just kind of enjoyed life.

I live in Seattle and have been depressed for a while. I had my Vitamin D3 levels checked via blood test, and they were really low. Started taking 5,000 IU per day, and I feel exactly the same as before.

Anecdotally, I had to bump up to 10,000 IU to see a difference.

Had super low Vit D. Was stuck in bed for a year. A few months of Vit D and a few other diet and supplements changes and I was out kayaking every weekend.

My experience anyway
