Not useful information on its own; it's a correlational study. If you filled a Vitamin D rx you were less likely to commit suicide. It does not show any causal relationship.

Maybe if you were able to get out of the house more easily and buy vitamins more easily you were less likely to commit suicide. Or if you were less likely you took better care of yourself (maybe less depressed?) and got vitamins. Or some disease that required vitamin D supplements was associated with lower suicide risk.

Not to say someone shouldn't follow up with a more rigorous study, but this is nothing more than a teaser for more serious research.


yugosaki t1_j7c5goe wrote

getting a vitamin D prescription filled also indicates this person is in regular contact with a medical provider.

Given that you can easily get vitamin d without a prescription, I'd say the fact they are seeing a doctor is a bigger factor.


That being said, anecdotally I find if I forget to take vitamin D in the winter I experience some seasonal depression and fatigue.


tempskawt t1_j7e9rjz wrote

I'm a vet in Wisconsin. Had a real bad time last year around January when I got back from a deployment to Saudi Arabia. Vitamin D supplements, running intervals, and eating an overly healthy diet fixed it after a while. Not sure if it was sunlight or heat, but it just felt like I had dread going on in the morning and the evening. Thermostat set to 70-72 range, and I would still shiver. Seems to have fixed itself since then. Would be curious to know if it was a fluke or if the/my human body is not good at adjusting to such jarring changes in daily sunlight.


yugosaki t1_j7egj5d wrote

Unrelated, but when I first read "vet" I interpreted it as "veterinarian" and was like "why would an animal doctor be deployed to saudi arabia" for a good minute before I figured out what I misunderstood


tempskawt t1_j7ei5nf wrote

There were veterinarians in Saudi! I guess they were vet vets. They took care of the MWDs, military working dogs. They were trained to take down bad guys, but most of the time they were sniffing the vehicles that local Nationals drove on base with. One guy had some fertilizer traces in his vehicle that an MWD indicated on. I got the opportunity to put on the padded suit and get attacked by one, they're no joke. Very well trained though!


juan2141 t1_j7em1jv wrote

Similar for me minus the deployment, I was feeling down lately then started taking vitamin D again. It didn’t take long until I started feeling better.

I have a doctor friend in England who says when Australians come over to the UK to work or study they are massively overrepresented compared to native brits in reporting seasonal depression and getting high dose vitamin d.

Why would I leave the house for vitamin D. I don't need a prescription and the Amazon man will drop it off without me having to talk to strangers.

Well, at my latitude only half of the year. The other half, even if you see the sun it wont help that much.

Because it's free outside from the sun.

some of us live places with not enough sun for our skin type and have to supplement anyway.

cmon sun


yugosaki t1_j7c5t1l wrote

plus even if there is technically enough sun, if its not warm out we're gonna be wearing long sleeves and pants, so the actual sun to skin exposure is limited a lot.


Mercury2Phoenix t1_j7cdqsm wrote

Or conversely, if you live somewhere super sunny & warm (like I use to live in Florida) you tend to be concerned about getting sunburns and skin cancer, so you still avoid sun (I was Vitamin D deficient (confirmed via blood work) when I lived there.)

Igotz80HDnImWinning t1_j7cjesz wrote

The VA ships it to your house. Also, this goes beyond a simple effect to show 1. A dose-dependent improvement (argues more strongly for a necessary or sufficient effect) and 2. A physiological model supporting their hypothesis because darker skinned folks have less vit D from the same amount of sun, and it had a larger effect in black veterans. I don’t love epidemiology, but this is far better than your average retrospective study and clearly points for a large randomized trial to be done to confirm.


Panigg t1_j7d678g wrote

Anecdotal but I was severely depressed before realizing I had massive vitamine D deficiency. Once that was taken care of my depression was essentially gone.


ShabbyKitty35 t1_j7ejfmy wrote

As a vet with PTSD, my worst downward spiral was when my Vit D was the lowest it’s ever been. I had to be put on max doseages for 6 months and will be taking a daily supplement the rest of my life to make sure it doesn’t happen again. Vit D, at least in my body, absolutely improves depressive symptoms.


altcastle t1_j7ekcxm wrote

Was it 10k or 20k ui? I know they got some mega doses out there. You can get too much eventually.

I take 5k right now in winter and prob 2k when I can go outside, and it’s not Hoth.


ShabbyKitty35 t1_j7ekhdy wrote

For the first 6 months it was 10k iu/day and 50k iu once a week. Now it’s 5k iu/day and in the winter I double it up every 3 days.


rosaUpodne t1_j7ce3jp wrote

If you take vitamin D regularly, you care about your well-being, so you probably don’t want to end your life.


korinth86 t1_j7cn1yi wrote

Vitamin D is already used to treat depression and low energy.

Many people spend all day in an office, car, or their home. Lack of sunlight is kind of a modern problem.

Taking a supplement is unlikely to harm you, but if you're concerned consult your doctor.


xaw09 t1_j7e9y1c wrote

It's pretty well established that one of the symptoms of vitamin d deficiency is depression.


themustacheclubbitch t1_j7en281 wrote

To not here. Vitamin D should or even must be paired with K2. Vitamin D on its own goes to your blood and fatty cells. Pairing K2 with Vitamin D moves it to the bones and teeth. Essential it’s where it is putting the calcium in your body. So if you were to say prone to heart conditions or breathing Vitamin D alone can worsen those conditions. Matched with K2 alleviates this problem and puts the calcium where it belongs.


triffid_boy t1_j7d6njj wrote

I agree with your post, but There is atleast a difference between low and high doses, with higher doses having the lowest risk.

A dose response relationship is always nice to see.


iperus0351 t1_j7is9nz wrote

Vitamin D is a precursor for dopamine. You need it to make the drug that your brain recognizes as happy. It is a dumb study because we already know the chemistry behind why it works. Vitamin D get on that, go about your life.


tkenben t1_j7fspsv wrote

Yes. People who take vitamin supplements are less of the mind to say "I've given up". It's sort of like saying hoarders and doomsday preppers are less likely to have suicidal thoughts.

Yeah I'm more inclined to believe that people who take vitamins are trying to take care of themselves, which of course means lower suicide rates. If I didn't want to live why would I give a s*** about vitamins?


54B3R_ t1_j7bui4f wrote

My mother says talking vitamin D is like a vitamin version of an antidepressant.

I also feel a difference in my mood, especially in the winter when the sunlight is minimal.

I know it's not scientific, but my own observations make me think those with low vitamin D might experience depressive symptoms. And many people do not go outside enough to get enough vitamin D.


Snoo-11861 t1_j7cgi8k wrote

It is scientific. Low vitamins D levels cause depressive moods. That’s why people further away from the equator have higher risks of suicide and depression. I use to live in the tropics and have had a deficiency since I moved to the States. Been taking vitamin D lately to cope and it has made winters so much more bearable


HamzaGaming400 t1_j7cvqmx wrote

I just had a thought. Maybe that’s why winter is always labeled as moody and depressive. While summer is the outgoing and happier season


Snoo-11861 t1_j7cw3x5 wrote

Yep, that’s one of the reasons why. It’s also probably why the holidays happen in the winter bc of how gloomy it is. Need something to look forward to


tifumostdays t1_j7d52cs wrote

No, it's more complicated than just vitamin d. People get much more light in their eyes know infer, and move more.


altcastle t1_j7ekmvo wrote

Plus we’re stuck inside and the days are short.


MaserGT t1_j7dr17b wrote

There is no scientifically determined connection between proximity to the equator and suicide. Geographic variation in suicide rates is most likely the complex interaction of differences in social organisation, cultural traditions, and biological/genetic factors. The only established link with geographic location is that living at high altitudes increases risk of suicide.


MaserGT t1_j7e7gk3 wrote

Have you read the journal articles you’ve cited? They provide compilations of data and make some statistical inferences, i.e. correlation. They do not, nor do they purport to, establish a causal link between latitude and suicide rates.

altcastle t1_j7ekl5e wrote

Vitamin D is one of two common supplements that has really helped me. The other is magnesium (anything but oxide, body won’t absorb it, I take glycinate.)

Had my doc recommend two others that seem to be helping as well, but I’m still journaling how I feel when I do and don’t take them.

Not wanting to die can be a job itself these days for some reason.


Larein t1_j7c4ltg wrote

In general suicide rates raise the more north you go. So lack of vitamin D could explain that.

Now this is incredibly interesting and actually does imply causation

Vitamin D is one of the few supplements a lot of scientists believe the daily value should be higher than the amount we set.

I didn’t understand the average dosage part. How much is that in UI?


lugialegend233 t1_j7buzti wrote

Unfortunately no, this is an observational study, not an experiment, so even strong correlations are just correlations.


W3remaid t1_j7bvn50 wrote

That’s interesting, since the case and controls were matched to account for confounders (health status, socioeconomic factors, etc) —what do you think the alternative explanation might be?


lugialegend233 t1_j7bwrpr wrote

One other commenters gave a really good one, people who fill out subscriptions are less likely to have committed suicide because they still care about staying alive enough to take care of themselves. Suicide is a damn complicated subject, but if one is considering it, making the effort of filling a prescription seems... pointless, and I think if we look at people who fill out any non-psychoactive drug vs. committing suicide, we'd see a similar correlation. (Psychoactive excluded because things like depression meds are specifically meant to reduce suicide risk factors, and I believe would confound any results)


W3remaid t1_j7bx4va wrote

That doesn’t really work because this is a case-control design, meaning that their health status is controlled for. If they were were sick to the point of being non-compliant with meds that would be reflected in their control match


lugialegend233 t1_j7bxo10 wrote

If suicidal thoughts are considered a health-status, then this whole study is pointless, because they're controlling for the thing which directly leads to suicide. Perhaps I'm misunderstanding your point?


W3remaid t1_j7by2o8 wrote

Well obviously you’re not going to control for your dependent variable, that’s the entire point of the study, but they’ve controlled for other health problems. If someone were decompnsated to the point of being unable to pick up prescriptions that would be reflected in their other medical problems. This is partly why psychiatric conditions can lead to physical illness


caltheon t1_j7cr0mz wrote

If that was true, then you wouldn't expect to see a difference by dosage as the act of filling a prescription for a low dose has the same amount of effort as filling one for a higher dose.


xdavidliu t1_j7f1d4z wrote

the people who had lower dosages of Vitamin D did fill out prescriptions too; and they had higher risk than those who had higher dosages.

I was a submariner. I started taking vitamin D after a psychologist gave my division a speech about her experiences with treating veterans who had alarmingly low vitamin D levels. The next time I went underway, I brought a bottle of 5000iu supplements with me, and it was a night and day difference. I started to feel like normal and part of a team, and not like I was in prison. I work nights and still take them sometimes, especially if I start to feel signs of seasonal depression or general depression symptoms.

I get better sleep with D, particularly more dream activity. Especially in darker winter months. Poor sleep would cause most of the things vitamin D reports to fix.

Note: D should only be taken in the morning


triffid_boy t1_j7d787t wrote

Vitamin D should be taken with food with some fat in, but there isn't great evidence saying you should avoid taking vitamin D in the afternoon or evenings. Logically, since you make vitamin D from the sun exposure during the day, natural vitamin D levels are probably highest around noon-2pm.

I started taking vitamin D and my depression symptoms improved, so I experienced that correlation first-hand. I began taking it per doctor advice. This was very much not the only change in my life at the time.

Some obvious confounding factors to consider: this resulted from first contact with a doctor regarding my depression symptoms and the initiation of a holistic care plan, began taking SSRIs, began therapy, changed living/working arrangements to remove sources of excessive stress, increased social contact with friends/family, generally started taking better care of myself when I was capable again.
