Vitamin D deficiency [WebMD] (or milder insufficency) is probably extra common than as soon as thought. It is difficult to obtain sufficient from food alone, as well as lots of people do not obtain sufficient from sun either. Although a 2016 New England Journal of Medicine article made headlines disproving buzz regarding a vitamin D deficiency “pandemic,” even their quotes are “of problem”: 6% of the populace, greater than 1 in 20 people.1 Stroll down a hectic road in Canada, Russia, or the UK– there’s even more deficiency in the north, as well as in the cloudiest and also smoggiest places2– and also you’ll pass a person with vitamin D deficiency every couple of secs.
That’s the low estimate: various other specialists have actually proclaimed that there is a pandemic of vitamin D shortage (or at the very least that it’s very typical) also in otherwise entirely healthy people.34.
An important dispute about the real occurrence and worth of supplementation rages on. But a lot of the controversy has to do with healthy and balanced patients– are healthy and balanced individuals deficient? Do healthy people require to take vitamin D? 5 What concerning individuals who in fact have illness? That’s a various kettle of fish! As well as people in chronic pain are a particularly diplomatic immunity.
The web link in between hypovitaminosis D as well as discomfort.
Vitamin D deficiency is suspiciously usual in people with chronic pain,6789 maybe due to the fact that it in fact creates it or at least makes it even worse.10 It is possibly more typical in people with details type of chronic pain, most notably fibromyalgia,11 which is a typical misdiagnosis.12 The signs and symptoms that cause the analysis complication include:.
Sweating, particularly head and face sweating, is among the quirkier signs and symptoms of vitamin D shortage.
muscular tissue and also bone hurting.
tiredness as well as weak point.
central sensitization, lower discomfort threshold.
inadequate workout healing: stronger pain that takes longer to vanish.
Regarding the bone hurting.
Bone aching is often mistaken for muscle pains just since people don’t anticipate their bloody bones to ache. The discomfort is a sign of osteomalacia particularly, which is type of like an evil twin of expanding pains: bone weakening brought on by malfunctioning bone building biology, not the same thing as osteoporosis13 The Mayo Clinic explains osteomalacia symptoms like so: “The boring, hurting discomfort connected with osteomalacia most frequently influences the reduced back, pelvis, hips, legs and ribs. The discomfort may be worse during the night, or when you’re putting weight on influenced bones.” Therefore, vitamin D deficiency may be a partial description for the extremely common sensation of early morning pain in the back.
I believe it’s possible that bone aching can occur even when osteomalacia is mild.14.
Concerning the muscular tissue aching.
The connection in between bone health and also vitamin D is familiar to most people, however muscle mass is extra obscure. Vitamin D really has plenty to do with muscular tissue, both muscular tissue pain1516 and disorder (weak point).1718 This may be why some professionals believe it is specifically widespread in individuals with a lot of “trigger factors” (muscle knots).19 Although the nature of trigger factors is vague as well as controversial, the role of vitamin D may really be just one of the secrets to comprehending them.
Vitamin D and COVID-19.
Vitamin D shortage might make individuals extra vulnerable to COVID-19, however nobody knows yet. The case for it was laid out in a mid-June 2020 testimonial (waiting for peer-review and publication). They wrapped up that is “biologically probable that Vitamin D shortage might contribute to susceptibility to COVID-19 infection. Nevertheless, there is no straight causal link yet between Vitamin D deficiency and boosted sensitivity to COVID-19.” The lack of proof is additionally highlighted by an NHS consultatory declaration. So this is pure uncertainty, as well as physiology has a habit of travestying expert hunches.
And additional vitamin D– don’t bother huge doses– are not also a plausible means to avoid or treat C19.
Vitamin B12 is fairly comparable.
Vitamin B12 shortage is practically a medical clone of D deficiency: there’s major symptom overlap, it’s surprisingly usual, and also testing is not as trusted as you would certainly believe. Yet B12 signs tend to be more neurological in character (extra tingling, extra strange experiences), and it is commonly extra ominous as well as hard to treat. See Mistaken Beliefs regarding a B12 deficiency.
That should be worried?
You are more probable to have a vitamin D deficiency if numerous of these factors describe you:.
People with darker skin.
People who do not venture out much, or cover their skin a whole lot (sunscreen or clothes).
People that live at high latitudes– anywhere the days obtain unbelievably brief in winter season.
Old individuals need more vitamin D. 20 (And the extremely young too, however there possibly aren’t numerous babies reading this attempting to fix their chronic pain.).
Both expecting ladies and also overweight individuals require even more vitamin D, so also “normal” degrees may not suffice.
Individuals who have diseases that hinder absorption of vitamin D in the gut (gastric sprue, brief digestive tract disorder, as well as cystic fibrosis).
If there’s only one supplement you’re considering your health and wellness and also your diet is good, it needs to probably be vitamin D.

Does taking vitamin D treat discomfort? Unknown! Maybe?
We know that vitamin D deficiency and also pain are most likely related– see above– however that does not necessarily imply that taking vitamin D is mosting likely to in fact help the pain. There’s probably not a benefit for any type of kind of pain patient, which is barely unexpected– there are various type of pain, and also it would be stunning if vitamin D benefited all and even a lot of them– as well as a pair of testimonials in 2015 and also 2016 both show this plainly.2122 (Although among them did actually find a minor advantage. Simply sayin’!) Both testimonials mainly just reveal the depressing state of the proof relating to the particular type of chronic pain that could be more likely to profit, such as fibromyalgia. The only studies of treating that condition with vitamin D are actually quite plainly positive.2324.
But “more research required” in a huge means! Beyond these scraps of evidence, in the meantime there is just educated presuming as well as professional experience.
Vitamin D is probably only one of many common factors in pain.
Nothing’s ever simple and chronic pain least of all: it’s usually caused by a sinister stew of factors that eat away at people for many years. Trying to solve the problem by fixing one thing– if indeed vitamin D is even a problem– may be about as feasible as trying to fix a broken engine with just one tool. Vitamin D deficiency may contribute to a chronic pain disaster over time, but by the time you’re actually in trouble the problem may be much more complicated than just vitamin D deficiency.
That’s a bleak warning not to put too much hope into vitamin D. But there are still reasons for optimism!
Vitamin D may be the most common and manageable factor in pain: the case for presumptive treatment.
The only thing worse than chronic pain with six causes is … seven causes. Obviously. Anything you can do to simplify the pain equation is a good idea, and you can certainly take vitamin D. (Just consult with a doctor first, please.).
Vitamin D deficiency can be fixed. It may be tough to get enough from diet and sunshine, but supplementation is cheap, safe, and effective, so it’s an ideal candidate for presumptive treatment: going ahead and treating based on the presumption of vitamin D deficiency even if it has not been established with blood tests. By all means do that too, of course! But if a lot of healthy people take this stuff “just in case,” it’s hardly radical for pain patients to give it a shot. There’s just not much downside to this one … and chronic pain is a major bummer. So talk to your doctor, get tested, and get supplementing– it could be a big deal for you.
Why not a vitamin D rich diet?
Because you ‘d have to eat a lot of fish.
It’s hard to get a meaningful amount of vitamin D from food. For pain patients, who are trying to make absolutely sure they are getting enough vitamin D, food is just not a rich enough source. Supplements and sunshine should be your main sources, but of course that doesn’t mean you shouldn’t also try to get as much as you can from food. Salmon is the best source– there’s about 600 IU in 6 ounces of salmon– followed by mackerel, tuna and other fatty fish. (Cod liver oil, if you can stand taking it, is so vitamin D rich that it’s almost like taking a vitamin D supplement.) Other than that, the foods with the most vitamin D are:.
Foods artificially fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals.
Fruits, veggies, and grains have almost no vitamin D.
How to take vitamin D supplements.
Although vitamin D supplements are cheap and easy and safe, they don’t always actually do the job. The vitamin D we can absorb through the gut is a little more awkward to “work with” than the kind we make from exposure to ultraviolet radiation. Here are some tips to make it work as well as possible:.
Take vitamin D3, not D2. (Most vitamin D pills are D3 these days).
Always take vitamin D with food, the more of it and the fattier the better. As a general rule, take it with the biggest meal of the day.25.
Take a fair bit, up to double the recommended dosage on the bottle. More about dosing in the next section.
It doesn’t matter if you evenly distribute doses. One big dose per day is fine.
Dosage: how much Vitamin D should you take?
There’s a more detailed discussion of dosage safety below, but here’s the bottom line in two points:.
There’s a large margin of safety in vitamin D dosing. You can double what’s recommended to healthy people in most countries without coming anywhere close to a safety concern.26.
But “megadosing” is silly — don’t do that!
☠ More is not always better! Although “megadosing” Vitamin D is trendy, please beware: taking more vitamin D than you need can kill you, starting with the destruction of your kidneys. Fortunately, it takes a lot. The rest of this article focusses on addressing concerns about the efficacy and safety of supplementation.
Supplement or sunshine?
Sunshine is preferable … if you can get it. The body is good at making vitamin D from sunshine, and even modest exposure can easily replace days of oral supplementation. Unfortunately, it’s just about impossible to get enough exposure in higher latitudes for large chunks of each year. Some tips and guidelines:.
DO NOT BURN. Plenty of vitamin D is made well before you burn, and burning is one of the most cancer-causing things there is. Aim for about half way to the start of a burn, which is just a few minutes for most people in strong sunlight.
Expose as much skin as possible. Every square centimetre counts, and just the skin of the face and arms is nowhere near enough.
The darker your skin, the more exposure you need.
Direct sunlight only. Windows block the ultraviolet radiation that you need.
Sunscreen also blocks UV and prevents vitamin D synthesis.
Use tanning beds only with great caution or not at all– see next section.
The Vitamin D Council website has a very detailed page about sun exposure (and much more).
What about tanning beds?
If they are used with the goal of resolving a vitamin D deficiency, tanning beds can be considered a kind of photobiomodulation therapy (PBMT), along with cold lasers, far-infrared radiation, and so on– exploiting the putative biological effects of electromagnetic radiation. But some experts are calling for a ban on tanning beds because of serious safety concerns, and it will probably happen eventually. Until it does, the option presents chronic pain patients with a tough dilemma. Unsurprisingly, their priorities have been ignored in the debate.
Tanning definitely produces vitamin D, but not as well or reliably as natural sunlight. And it’s well-established that tanning lamps are full-blown carcinogenic, no question– just like the sun, or possibly worse.27 And so it may not be worth the risks, and at the very least it’s critical to limit your dosage. Above all, do not use tanning beds to tan! If you use them at all, use them in moderation.
The main public health issue with tanning beds is not that they are much more dangerous than sunshine, but that people use them to overdose on UV (and even get addicted to them). It’s way too easy to get too much UV in a tanning bed, especially when used with the goal.
Of course, it is possible to control the dosage and use tanning beds temporarily for shorter durations, thus hopefully reducing the risks while still being stimulated to produce large doses of completely bio-available vitamin D. This is called “safe tanning,” and some experts think it’s a myth. However, their arguments boil down to “better safe than sorry” rather than resting hard evidence that it’s actually dangerous. There are three good points to consider though:.
They may be more dangerous than has yet been confirmed (but no one’s totally sure of that yet).
Vitamin D supplementation mostly work just fine.
Quality control and standardization of tanning beds are sketchy. Many tanning beds are not actually as good as sunshine anyway (different kind of ultraviolet), and it’s impossible for customers to know what they’re actually getting– which is a standard problem with all virtually all consumer medical hardware.28.
All of that should be a deal-breaker for almost everyone. But it’s not necessarily a deal-breaker for chronic pain patients.
Maybe chronic pain patients should take the risk.
Tanning beds are not safe (definitely true), but neither is sunshine (also definitely true), and the stakes with chronic pain and vitamin D deficiency are extremely high (all too true). For chronic pain patients whose lives are being ruined, the limited risks of careful UV exposure in a tanning bed may “pale” in comparison to the greater danger of the pain.
If you prefer to play it safe, stick to supplementing. If you are in rough shape and desperate to rule out vitamin D deficiency as decisively as possible, do some tanning but follow these rules of thumb to minimize the risk:.
Use low-level or low “pressure” tanning beds only. No fast tanning!
Quit well before you start to burn: just 4-5 minutes if you burn easily.
Limit your sessions to 1-2/ week for a couple months– its only purpose is to be as sure as possible that you get plenty of vitamin D quickly, to reduce uncertainty in the results of the treatment experiment.
A more detailed look at dosing safety: are higher dosages of Vitamin D really safe?
I’m not talking about megadoses over 20000 IU per day. That’s just silliness: although it’s probably not dangerous, it might be, and it’s not necessary. This is more about the kind of dose you can easily find for sale in drugstores: 5000 IU capsules are quite common. Dr. Harriet Hall has reasonable concerns about that:.
A Walmart ad in my local newspaper trumpets “75% of all Americans don’t get enough Vitamin D” and offers to sell me Maximum Strength Vitamin D3, 5000 IU capsules to “promote bone, colon and breast health.” Meanwhile, the Institute of Medicine (IOM) tells me that “the majority of Americans and Canadians are receiving adequate amounts of … vitamin D” and that no one should take more than 4000 IU a day. Apparently Walmart and the IOM aren’t talking to each other.
Indeed, the official recommended dosage for adults is 600 IU per day, with a tolerable upper intake level for D for adults of 4000 IU.29 If we’re going to break those rules, there had better be a compelling rationale and evidence of safety. I have looked very hard at these questions repeatedly over the years.
The first reason to break the rule is a good one: it is probably wrong due to a “serious calculation error,” reported by two groups of researchers.30.
In any case– even if there was no error– the Walmart shopper looking at a sale on 5000 IU vitamin D capsules thinking it might help them with some vague symptoms like fatigue is a completely different critter than the chronic pain patient wondering if, perhaps, their vitamin D deficiency could be a factor in their horrible problem. Is the average person deficient? Do they need 5000 IU per day? Probably not. That is what the IOM guidelines are concerned with.
But the pain patient might. The geometry of risk and benefit is different for pain patients.
Fortunately, there is a wide margin of safety error with vitamin D dosing, especially with relatively short term usage. There is no question that truly excessive vitamin D can be dangerous,31 nor any question that it takes a lot, sustained for long periods. Even megadoses of 50,000 IU/day have failed to cause any trouble, and when supplement baron Gary Null overdosed on vitamin D in his own contaminated product– talk about poetic justice– he was taking upwards of two million IU per day. That nearly killed him, but it still didn’t, and we’re talking about a dose five hundred times larger than the IoM’s upper limit– such a ridiculous number that I’m really only bringing it up as a fun example. Here’s a summary of the safety evidence from Heaney:.
Both the intoxication literature and the recent controlled dosing studies have been reanalyzed by Hathcock et al. These authors show that essentially no cases of confirmed intoxication have been reported at serum 25( OH) D levels below 500 nmol/L. Correspondingly, the oral intakes needed to produce such levels are in excess of 20,000 IU/day in otherwise healthy adults and, more usually, above 50,000 IU/day. These findings led Hathcock et al to select 10,000 IU/day as the tolerable upper intake level (TUIL, or UL), with considerable confidence.
I also discussed the toxicity issue briefly with Dr. Hall (quoted above). She agreed that anything under 50,000 IU is unlikely to be toxic (and again that would be especially true for temporary supplementation for deficient patients).
Anything up to 5000 IU is still comfortably within the margins of safety for short term supplementation (several weeks to a few months). There is zero evidence of risks up to that dosage, and the IOM just substracted 20% from that just in case.32 Meanwhile, others are still vigorously arguing that their 7000 IU may be both safe and actually necessary for anyone deficient.33.
