- Vitamin D. I don't know why so many people are obsessed with it, but there are two new studies out about it in JAMA Internal Medicine. We've even got multiple episodes of Healthcare Triage about it. What's one more? This is Healthcare Triage News.

I'm more interested in whether there's vitamin D trials on mental illness/mood. It's often prescribed for SAD (seasonal affective disorder) or "winter blues" in very cloudy/cold areas (like Canada...there's just so much grey here in the winter).
Kieran Mcgarry I have bipolar disorder and Vitamin D was suggested to me to reduce depression issues. I think it was also suggested because I live in the beautifully cloudy Pacific Northwest.
garvythecapricorn Same here, except I've just got regular depression. I don't know if I was deficient before, or if it has any effect at all. I'n not much one for placebos.
Excercise?! But I need a one-size-fits-all solution that means I don't have to get up!
Ehh the problem is that many, many people are deficient in vitamin D. I was/am one of those people and I do benefit a lot from supplementation.
Vitamin D is still a good supplement for people who live in northern regions with lack of sun is it not?
Northern Canada being the north I am talking about.
vcostor Yeah, living in a really cold place with very little sun for a huge chunk of the year, I had been found to be fairly deficient in vitamin D. It's really not uncommon, and it's kind of annoying that he didn't clarify that actual deficient people were not the focus of the studies.
Wow, this is awesome. I was literally just thinking about vitamin D and healthcare triage this morning..... weird coincidence....
As someone who's been vit D deficient in the past, this was fascinating. I'm hadn't heard about any of this before.
I would say deficiency sucked, made me get tired early on in the day, so maybe don't go the other way and stop thinking it's important- balance is good (also exercising got me out in the sun more, thus helping my deficiency so yay exercise :) )
Socken Yeah, these kind of studies don't address people with an actual deficiency. I'd hate for people who really need supplemental Vit. D to stop taking it based on them.
Dave Power The problem is, however, that the estimates vary widely on how many people actually are affected by a vitamin D deficiency. None of my doctors have ever asked me about vitamin D or measured my levels (which still wouldn't have solved the problem of knowing what the levels ought to be) while most of the scientists I heard on the topic said something to the effect of "In Winter? Where _you_ live? Almost everyone is deficient."
Anyway, while people still figure this out, I'd rather err on the side of taking a cheap, safe and useless supplement than on the side of "woops, we now know you should have taken that cheap supplement that's almost impossible to overdose for the last ten years and now you've been lacking this important hormone that's involved in all kinds of functions sorry not sorry kthxbye."
Dave Power This is what kinda bugs me about videos titled like this. They are not 'debunking vitamin D', they are going over specific myths. It would be like producing a video entitled 'exercise debunked!' and going over myths regarding specific exercises and their failure to produce various outcomes people thought they did.
Tackling myths and hype are great things, but such packaging has a real 'baby with the bathwater' feel to it.
Aaron, since you know John, can you tell John to tell Hank to redo the scishow episode on GMOs?
***** Because it was a pretty terrible video.
If I remember correctly, it cited some bad research.
Hank confessed to fucking it up badly, and he promised to remake it TWO FUCKING YEARS AGO!
Diana Peña i0.kym-cdn.com/entries/icons/original/000/010/437/Oneeternitylater.jpg
Well, Sasha, that fits disturbingly well...
Diana Peña By the time he remakes that video, we'll be able to cure world hunger with GMOs.
Or, depending on one's (erroneous) viewpoint, we'll all be dead because because GMOs are part of some eugenics conspiracy.
The thing about these debunk studies are that they are done based on random things like falls. Or done on patients with severe conditions. When it doesn't solve those things, people use the studies to claim it's completely useless to supplement. Of course on the other side people over-emphasize or make outrageous claims of the actual benefits, but I still err on the side of supplementation. If they could do life long studies of people with similar exercise habits and food habits, with vs without supplementation then that would be amazing... but they can't, so it's super debatable when it comes to supplements. I would say it breaks even as far as studies that purport benefits vs no effect.
Does the video keep going black for anyone else? I just have to move the scrollbar to get it back, but it happens again after a few seconds.
Take Walker
Yeah, its happening to me, too
Adnan Ilyas Yeah, me too. I've also had a lot of videos not working on mobile, youtube is doing some weird stuff lately
Take Walker This has been happening to me generally on RUclips today. I'm sure it will clear up soon, as it sounds like a general issue.
Okay, I kinda figured it was RUclips.
Take Walker Yeah this seems to be a problem many people are having with the html5 player. If you find an extension or addon for your browser that forces RUclips to use the older flash player, it seems to fix up the problem. Hope this helps.
I wish there was a vitamin d playlist
I'm participating in a double blind with placebo study about vitamin D right now. It's called "Muscle-Related Side Effects of Statins: Functional Impact, Mechanisms, and Potential Relief with Vitamin D Supplementation", maybe you'll talk about it when it's published!
Here it is: clinicaltrials.gov/ct2/show/NCT01493648
Modified Yoga is safe and works to improve balance in elderly people and keep them from falling. Galantino 2012. I'm reading a book called "The Science of Yoga" which sorts out the good and the bad studies of yoga and its advantages and its potential dangers
I'd like to see a study showing the affects of oral vitamin D supplements on people who are actually deficient. Vitamin D is a big problem were I am, when 6 months of the year you simply won't be out in the sun, it's down when you get to work, and setting when you leave. It's easy to say "just get outside more" when you live somewhere mostly sunny.
Please do an episode on MSG!
I hate these studies that focus only on Vitamin D in respect to its effects on calcium, when Vitamin K2 is the deciding factor on what Caclium does in the body. It release two proteins which literally pull calcium from places where it doesnt belong and puts it where it belongs. If you k2 levels are insufficient, no amount of vit d and calcium supplementation will really help. Thus having that confirmed in studies is basically meaningless.
+Kinta02 thanks for pointing it out!
+Kinta02 Thank you, you brilliant sumbitch!~

Hi Doc. People think "bone" when they hear Vit D, but how about discussing some of the other important things associated with it? MS in high latitudes, cancer, death by all causes, etc...
I'd love to see a video on the viability and efficacy of functional medicine practitioners.
Thank you for FINALLY getting a FB page!
Healthcare Triage My doc prescribed vit D supplementation because (after testing) my level was below normal range. They did the same for B12 and folate too, after specific blood tests on those. Is this wrong, as a general strategy?
FWIW the outcome concern they had (for both) was not bone density or blood pressure (mine are fine), but depression.
Sai I think the gist of the video is to discourage sole reliance on Vitamin D for preventing injury in the elderly population, and instead to promote physical exercise (perhaps in conjunction with Vitamin D supplements to decrease the risk of the fall injuries.
If you are seeing a doctor and they prescribed you vitamin D due to a deficiency, take it! :)
wrathfulgrapes Well, he talks about "debunking" benefits of Vit. D as if he were talking quite broadly, but he only cites studies that are for elderly injury prevention. Those are pretty radically different claims. ;-)
Yeah I think it could have been clarified a bit better.
So, if not preventing actual injuries, what benefits does Vitamin D have anyway?
IJethrobot Helps with absorption of calcium, magnesium, iron, phosphate, and zinc. Because it helps with mineral absorption, it's used to treat rickets.
I was on hold with my doctor's office yesterday and they kept playing a PSA about how important vitamin D is.
I don't understand how the graphs line up with what he's saying; the Vitamin D + exercise groups seems better off than the exercise + placebo group, and the other graphs seem a bit off too.
Falls aren't the only reason to want to supplement bone density. People on depo provera are at risk for bone loss. Calcium supplements apparently don't work, Vitamin D is recommended instead.
How about: over-the-counter Magnesium supplements that people report as reducing heart palpitations and other heart and muscle nerve issues?
Maybe they didn't get enough vit D nutritionfacts.org/video/the-optimal-dose-of-vitamin-d-based-on-natural-levels/
and was it vitamin D3, how much vitamin A did they get? And did they get any K2?
No mention of dosages used in the studies? That's slightly important considering there is contention to the appropriate amount we should be getting in the first place.
bakslashr There is always a mention of dosage in the studies, but this was a report on a meta-analysis.
Isn't vitamin d in general important for many processes in your body beyond bone maintenance? I sleep during the day and never get sunlight so it seems like a supplement is vital.
The only benefit I've heard of associated with Vitamin D is mood--supposedly vitamin d synthesis from sun exposure improves mood, and this can be mimicked somewhat through d supplementation. Any research on that front?
Could someone direct me to the other episodes about vitamin D? Also, have they covered weightless and vitamin D?
My doctor prescribed vitamin D in response to a blood tested deficiency AND the fact that I have high blood pressure. Sounds like the blood pressure part isn't going to help. But is a (smallish) deficiency still a problem? Are there benefits to vitamin D supplementation in general?
I'm concerned that this video seems to throw the baby out with the bathwater. Are we saying it doesn't do the things we think it does? Or are we saying not to supplement, period? This needs to be clarified.
Better to see trials that test vitamin D through sun exposure then supplementation. The way you assimilate D through sunlight differs from he way we assimilate it through a supplementation. If your designed to make it endogenously, your not supposed to take it as a supplement. Better to get it the way you were designed to get it.
I was hoping there would be a link to the other two HT vitamin-D videos...
I did a RUclips search and only found one other video mentioning vitamin D...
That puts you ahead of me; I wasn't willing to do the effort to do the search. :)
You are giving people a false sense that Vitamin D supplementation is irrelevant in diet. You should mention that Vitamin D is NEEDED for the expression of over 1,000 of our genes. Most of the population is deficient in Vitamin D. Or what about the correlation of Vitamin D and testosterone levels. Or that the studies that show Vitamin D can prevent a VARIETY of cancers.... Many of your videos state what specific supplementation cannot do.. why not explain what they can do.
OK but these studies werent in patients with LOW levels of vitamin D?? why would you give vitamin D to someone who already has healthy levels?
I keep seeing stories/ads about how cancer supposedly can't survive in a body who's PH is more alkaline than acidic. Is there any truth to that and can we really effect our PH levels that much?
Um, our bodies are already slightly alkaline...
Also, no, you can't change your body pH.
***** pH diets are among the craziest. You can't change your blood pH no matter what you eat, and blood pH is very tightly regulated.
But, is this new study, using higher amounts of vitamin D? With the old standard that comes in multivitamins, your not getting enough.
So can we get this "exercise" thing in a pill too? ;)

What about vitamin D deficiency?
Please do blood pressure
What, I thought the body can produce vitamin D
One could always exercise AND take Vitamin D...
looking at the price on vitamin d3,
even if there is a 1% or half of a % its still worth it.
Well, that's fine, but just don't get it expecting a miracle cure.
Skeletal exhibitionists rejoice!
What about vitamin D and depression? My doc has me taking it...
desertraven Currently the research is inconclusive. But very little has been done. There have been a few studies that show that people who report SAD are not more likely to be vitamin D deficient. Even if there's a link, there's a possible misinterpretation in causality - that depression causes people to move around and go outside less, lowering their vitamin D levels.
dbe471 I'm a psych major - I don't pretend to be an expert on the subject - but I did figure it was some sort of feedback loop... Depressed because of low vitamin D... so don't go outside/eat well to get vitamin D... become more depressed because of low vitamin D...
Kinda like obese people and depression... Sad because they're fat, eat because they're sad, sad because they're fat...
Darn all this time I thought that Vitamin D was the new Vitamin E i.e. the new panacea
We still need some vitamin D, right? This is just about Vitamin D supplements?
Well there goes all my hope for having an enjoyable retirement. I keep hoping that one of Dr. Oz's magic berries or supplements will eliminate the need for exercising but they never do. :(
Blood pressure
"Physician functioning?"
High blood pressure
I wonder if HT is evidence of god's existence. Because Aaron is doing his work :D
Well of course exercise is better for balance and strength than a vitamin pill! What did you expect? For it to be some kind of steroid? And according to the graph at 1:19, vitamin D does seem to have an effect on the rate of injuries, which makes sense as better bones density relates to better bone strength and less fractures. The effect seems to be a small 1-ish%, but the pill is cheap and you're not doing harm; might as well take it. It doesn't stop you from doing exercise. And you should exercise, to avoid injury and for a slew of other reasons.
Sorry, Aaron, but it seems to me that your dislike of vitamin supplement makes you draw conclusions way too fast, while the link between lower bone density and fracture is well established. Because physics.

Did anyone else read the title as "Vitamind?"
this is just stupid,...
it's like a take off on greger,..
as some say: "oh my" !
