Yup.
Melanin protects you from melanoma & other skin cancers, but limits your ability to synthesize the D.
是的。
皮肤中的黑色素可以保护你免受黑色素瘤和其他皮肤癌的伤害，但却限制了你合成维生素D的能力。

有趣的理论，我承认它很有说服力。不然自然不会筛选出浅色皮肤，尽管浅色皮肤增加了患皮肤癌的风险?

That’s why light skinned European people developed the skin mutation. Pale skin synthesizes more Vitamin D in regions where there is a lack of sunlight.
And the diet included more fish at the higher latitudes. However it would remain a challenge until sunlamps and supplements appeared.
这就是为什么欧洲人会产生浅肤色皮肤突变。在缺乏阳光的地区，苍白的皮肤会合成更多的维生素D。
而且高纬度地区的鱼类也更多。然而，在太阳灯和维生素补充剂出现之前，任何维持正常维生素D水平仍然是一个挑战。

Yes, I remember reading that fish nutrients were extremely important in early European diets. Salmon, herring, sardines, and cod are all fish in the early European diets that are high in Vitamins A & D. The early Scandinavians even produced and consumed cod liver oil during the winter months. It was later discovered that cod liver oil could be used to treat Vitamin D deficiency, fight rickets, and treat rheumatism. The Vikings were really ahead of their time!
是的，我记得我读过一篇文章，说早期欧洲人的饮食中，鱼的营养非常重要。鲑鱼、鲱鱼、沙丁鱼和鳕鱼都是早期欧洲人饮食中富含维生素A和维生素D的鱼类。早期的斯堪的纳维亚人甚至在冬季生产和消费鱼肝油。后来人们发现鱼肝油可以用来治疗维生素D缺乏症，治疗佝偻病和风湿病。维京人真的走在了时代的前面!

Vitamin D is a hormone and we don't fully understand what it's doing in the body. It has some properties of steroids like cortisone and may suppress the immune system in excess.
I would be careful with supplementation, just as I would be careful with other medication. Did you know high dose antioxidants may infer with your bodies ability to kill cancer cells? E.g. vitamin A supplementation increases lung cancer risk.
维生素D是一种激素，我们还不完全了解它在人体内的作用。它有一些类固醇的特性，就像可的松，过度摄入维生素D，可能会抑制免疫系统。我会小心使用维生素D，就像我小心使用其他药物一样。你知道高剂量的抗氧化剂可能会降低你身体杀死癌细胞的能力吗?
例如:过量补充维生素A会增加患肺癌的风险。

I appreciate your comment because I supplement with D3 and live in an area known for D deficiency. I have considered taking more than one 3000IU capsule if it could help me, but I do not know enough about the toxicity risk. While I'm about to go do some research for myself, could you also recommend some sources for learning about how much vitamin D my body might produce in the sun, and whether exogenous supplementation is different than endogenous generation in terms of safety in quantity?

Not the user you asked, but: Blood tests are the only sure way of knowing your vitamin d levels. That said, the amount of vitamin d produced in the sun is dependant on your skin type, amount of uv, exposure time and exposure area. Vitamin d received from sun shouldn't lead to overdosing, since there seem to be mechanisms preventing that. They don't exist for consumed vitamin d though, so you can overdose by taking too much but d. That would require a lot though. Based on the studies I've read, if you exceed 8000 IU daily for an extended period, risk of an overdose exists. At 4000 or lower you should be safe. Note however, that without blood tests, you simply don't know. 1000 should be safe for anyone, but might not be adequate if you have really low levels. I'm not a medical professional though, this is just info I've obtained. I go through yearly blood work and with 4000 IU daily I get my levels where they need to be during winters. During summers I stop and get it from the sun. I use UV index to estimate exposure times to minimize skin cancer risks.
我不是专家，血液检测是帮助你了解自身维生素D水平的唯一可靠方法。也就是说，在阳光下合成的维生素D量，取决于你的皮肤类型、紫外线量、暴露时间和暴露面积。从阳光中摄取的维生素d不会导致过量摄入，因为人体似乎有机制可以防止这种情况发生。
但口服摄入会导致维生素d摄入过量，但你需要吃大量维生素D才会导致摄入过量。根据我读到的研究，如果你长期每天摄入超过8000IU维生素D，就存在过量摄入的风险。摄入4000IU或更低的量，你应该是安全的。但是请注意，如果没有血检，你根本不知道自身的维生素D水平。1000IU对任何人来说都是安全的，但如果你血液中的维生素D含量很低，可能就不够了。我不是医学专家，这只是我得到的信息。我每年做一次血液检查，每天摄入4000 IU维生素D，我血液中的维生素D含量达到了冬天需要的水平。夏天的时候，我会停止服药，多晒太阳。我用紫外线指数来计算晒太阳的时间，将患皮肤癌的风险降到最低。

have MS and there has been shown to be a strong correlation between vitamin D deficiency and rate of MS amongst a given population. So much so that any neurologist will tell you to start taking vitamin D as soon as you are diagnosed with MS. My understanding was that at most latitudes, spending time in the sun won’t get you close to the amount of vitamin D that is beneficial. I take 4000 IU daily now that my vit D levels are in a good place (I have blood taken monthly), after having previously dosed at 10000 daily.

The problem here is that vitamin D supplementation seem to have little effect on cancer (though this can of course change with future studies). What most Vit D studies miss is that Vit D is a cofounder in a lot of cases. Old age and disease led to low vitamin D levels, but are not necessarily caused by low vitamin D levels.
That's why many studies show correlation between ill health and inadequate vitamin D, but shows little improvement when given vitamin D as a supplement

This thread is full of praise for vit d but probably without good evidence.
Currently we know for sure that vitamin d is important for bone health. That is what we know.
Otherwise most of the evidence for vitamin d is correlation. When they do suppliment studies there is no evidence that supplimenting helps anything other than bone health.

Otherwise I tend to find wiki is pretty reliable and it states much the same as what I have said.
I use a few medical resources that are behind pay walls and they tend to say the same thing too.
In Australia where I work the government has asked doctors to cut down the amount we test vit d because it is largely a waste of money outside of osteoporosis.

Back in April, when I first read that Vit D mitigated the severity and number of symptoms of Covid -19 (and I took a job as an essential worker) I began taking it daily. A few weeks later I was a different person and the only thing I changed was taking 3,000 UI of Vit D. My depression lifted and I had better energy and focus.
I had been ignoring my doctor's suggestion to take it every day for a few years. Now I know better.

Being outside correlates with higher Vit.D levels, going outside more means walking more, interacting with people more, petting more neighborhood puppers. It means you don't hate yourself and aren't afraid to be judged.
我相信这个推论。我和这类人群相处过很多次(我住在管理精神病患者的教养院)，精神病患者的头号爱好就是躲在暗处，从不出门。
经常身处室外的人，体内的维生素D水平基本都很高。更多的外出意味着更多的步行，更多的与人互动，更多的抚摸邻居的小狗。这意味着你不讨厌自己，也不害怕被别人评判。

I discovered that I had a vitamin D deficiency (10ng) and started supplementing D3. It has resolved a lot of my insomnia issues, sleep deprivation and general fogginess.
Blood serum D3 lab results are given in 10 ng/mL factors typically. Levels are usually grouped as follows:
0-10ng: highly deficient and at risk for bone weakening; can't efficiently absorb bioavailable calcium. Osteoporosis, bone fracture risk in the long-term.
10-20ng: deficient and at risk for the same factors as above.
20-30ng: low but normal
30-40ng: normal
40-50ng: normal
60-70ng: high but normal, shouldn't supplement
70ng+: high, don't supplement
150+: toxicity may occur, vomiting, nausea, constipation.
One common misconception is that people who live in sunny areas don't have vitamin D deficiency. While sunlight does produce Vitamin D from dermal reactions, it's still possible to be deficient even if you spend all day in the sun. Elderly, dark skinned people, genetic dispositions, etc. can all contribute to not manufacturing enough vitamin D from UVB light.
我发现自己缺乏维生素D ，于是开始补充维生素D3。它解决了我的很多失眠、睡眠不足和迷糊的问题。
针对血液中的维生素D浓度标准，实验室以10 ng/mL为一级，划分了以下几组:
0-10ng:高度缺乏维生素D，有骨质弱化的风险;不能有效地吸收生物有效钙。具备患上骨质疏松、或骨折的长期风险。
10-20ng:依然具有缺陷和风险。
20-30ng:低但正常
30-40ng:正常
40-50ng:正常
60-70ng:高但正常，不应补充维生素D
70ng+:高，不要补充维生素D
150+:可能发生毒性作用、呕吐、恶心、便秘。
一个常见的误解是，住在阳光充足地区的人不会缺乏维生素D。虽然阳光确实能通过皮肤反应产生维生素D，但即使你整天在阳光下，仍然有可能缺乏维生素D。老年人、深色皮肤的人、遗传等都因素都可能导致晒太阳产生不了足够的维生素D。

Do your due diligence if taking vitamin D, apparently it needs to be supplemented with Vitamin K so the body absorbs the calcium correctly.
如果你在服用维生素D，显然还需要补充维生素K，这样身体才能很好地吸收钙。

Meanwhile in the Netherlands .... our foresighted and infallible government took Vitamin A and D daily supplements off the base health insurance in 2019. If you are prescribed the monthly tablet vitamin D tablet that's still covered for now, otherwise you are expected to go down the store and buy them. We all know how well that's going to work for older people on a limited pension
我们有远见的荷兰政府，在2019年从基本医疗保险中取消了维生素A和维生素D，如果医生给你开的是每月服用的维生素D片，那你就得去商店买了，用有限的养老金，这个政策对老年人来说是多么有用。

That is what I actually read before, someone suggested taking Vitamin D could lead to a magnesium shortage or could boost a long time magnesium shortage and that could lead to high pulse and blood pressure rise. I also read that it could take 6 to 12 months to get rid of it.

I have lots of health issues and already had high blood pressure, but taking Vitamine D literally makes it worse, that my already high rest pulse and blood pressure gets boosted by it by 20-30% and I get heart racing too for several days. I tested this now a few times, taking it and dont taking it, normalized it again after a week or two.
我有很多健康问题，已经患有高血压，服用维生素D确实会让情况更糟，我本来就很高的脉搏和血压会因此增加20-30%，我的心跳也会加速好几天。我现在测试了几次，不服用维生素D，一两个星期后脉搏和血压就会回归正常。

Vitamin D or D3 is the new cure-all pushed aggressively to the market. It was already pushed hard in 2011 but hard evidence for vitamin D health claims remains lacking to this day. A lot of may, can, could but not many robust results. If you are deficient, yes it may be beneficial. But no one has evidence if being old and frail is the reason for being vitamin d deficient or if it is the other way round.
维生素D或D3是推向市场的新“灵丹妙药”。早在2011年，人们就已经开始大力推广维生素D，但至今仍缺乏证明维生素D有益健康的确凿证据。很多“可能”、“也许”、“大概”的测试结论都不太可靠。是的，维生素D可能是有益的。但是，没有证据表明是疾病导致了维生素D水平下降，还是维生素D水平下降导致了疾病。

I am A Scientist™ and there's enough evidence for vitamin D supplementation being beneficial and most of us not getting enough that I do take a vitamin D supplement daily.
You're especially likely to have low vitamin D if you live further from the equator and if you have darker skin; for most of the U.S. there's not enough sun in the winter to make vitamin D, no matter how much time you spend outside. Just don't go crazy with it and take insanely high doses, because it's a fat-soluble vitamin and you can take too much and end up with toxicity.
我是一名科学家，有足够的证据表明补充维生素D是有益的，但我们大多数人摄入的维生素不够，所以我每天都服用维生素D补充剂。
如果你住的地方离赤道较远，而且你的皮肤颜色较深，那么你体内的维生素D含量将会很低;对于大多数美国人来说，无论你在户外呆多久，冬天都没有足够的阳光来产生维生素D。但不要过量服用，因为维生素D是一种脂溶性维生素，服用过多会导致中毒。

There isn't really a single straightforward answer to that. The upper limit on what is recommended as safe is 4000 IU/day from all sources (total of supplement + food). How much it takes to actually cause harm is less clear and it depends on the person and the dosage frequency and how we're defining toxicity and harm.
If you're not taking incredibly high doses as a supplement you're probably fine unless you have some underlying disorder affecting vitamin D metabolism.
200,000 IU a day is definitely too much. They did that in the 1940s and people developed hypercalcemia. 50,000 IU once every two weeks was found to be fine for the 6 years it was monitored in one study. Another study found that 20,000 IU per day made blood levels go up significantly (like higher than is recommended), but no evidence of toxicity,
I wouldn't take over 4,000 IU/day personally, and I think it's unwise to do so unless you have a good reason and are having you blood levels checked by a doc. Just because they couldn't find evidence of toxicity in a small sample of healthy adults in the time frx they were checking doesn't mean that it's completely safe for everyone.
这个问题并没有一个直接的答案。建议的安全上限是4000 IU/每天，摄入的总和(保健品+食物)。到底要摄入多少才会造成伤害目前还不太清楚，这取决于人，剂量的频率以及我们如何定义毒性和伤害。
如果你不服用高剂量的维生素D，你可能不会有什么问题，除非你有维生素D代谢障碍。
每天200000IU绝对是太多了。他们在20世纪40年代做过试验，人们患上了高钙血症。在一项研究中发现，每两周5万IU的维生素D摄入，连续吃6年是可以接受的。另一项研究发现，每天2万IU的维生素D摄入，会使血液中的维生素D含量显著上升(高于推荐水平)，但没有证据表明会产生毒性。
我个人不会每天摄入超过4000IU的维生素D，而且我认为过量摄入是不明智的，除非你有充分的理由，并让医生检查你的血液。人和人的体质不一样，有的人可以大量摄入维生素D，并不意味着大剂量对每个人都是完全安全的。

Does it prevent the cancer or just the death?
Keeping people with cancer alive longer is not really a benefit to society.
We all pay more for them to die more slowly.
If it eliminates or prevents the cancer altogether wonderful.
However just keeping people with cancer alive longer is not productive.
维生素D是预防癌症还是延缓癌症患者死亡?
让癌症患者活得更长对社会没有好处。
我们付出更多资源，只是让他们死得慢一些。
如果维生素D能完全消除或预防癌症那就太好了。
