Isn't the oral intake pretty much negligible anyway? I remember getting a vitamin d supplement in a syringe (to be put on bread, from a physician) containing a very large dosis. I'm not stating the dosage is wrong. Looks like it is anyway.
It is easily possible to overdose on oral Vitamin D tablets and damage your body.

So? What's your claim here? Are you claiming that our skin works the same way as our digestive system? That would be a ridiculous claim. And fyi, many people get a proper sunburn, if they stayed in the sun for 30 min straight without protection, at least in summer. So your 30 min statistic doesn't really tell us anything about something being healthy or not.
I've given you everything you need to find out for yourself. Your incredulity on this is a self-confession.

Only recently again I read in the newspaper, that most products are overdosed. There is a typical number that the vitamin D products usually show, and in the article it said, that only up to 800 IU is safe, and everything above is an overdose. There are many products out there with 2000 UI or maybe even more. Beware. EDIT: Wow, the HN-local doctors at it again. Imagine getting downvoted for sharing information from n…
Being at the beach (in summer) for a half an hour will produce 10,000 and 25,000 IU for the average european. See: Vitamin D and health: evolution, biologic functions, and recommended dietary intakes for vitamin D (293 citations)
Please do not take 5000mg/day of Vitamin D. The author confuses IU and mg which is very dangerous.
It's unbelievable crazy what the author suggests, even say "10,000 IU if you're feeling daring / have darker skin / live in less sunny climates.". Just a simple look at the side effects of high dosages: Safety and side effects Taken in typical doses, vitamin D is thought to be mainly safe. But taking too much vitamin D in the form of supplements can be harmful and even deadly. Taking more than 4,000 IU a day of vitam…

According to the internet, it is way higher, probably over 9000. Edit because the comment might be to shallow for HN: I sympathize with the struggle against depression and, after first-hand experience, share the skepticism against the widespread prescription of antidepressants and the methods of evidence presented for it. Very serious and important topic. Regarding Vitamin D, I am also supplementing in the Winter, bu…
It’s important to take Vitamin D, as a fat soluble vitamin, with dietary fat during a meal. Something about bile production and absorption. Also important to take it with Vitamin K.
Seems like it would be best to increase time spent outdoors though.

So 5000 IU is the recommended amount?
> A statistical error in the estimation of the recommended dietary allowance (RDA) for vitamin D was recently discovered; in a correct analysis of the data used by the Institute of Medicine, it was found that 8895 IU/d was needed for 97.5% of individuals to achieve values ≥50 nmol/L. Another study confirmed that 6201 IU/d was needed to achieve 75 nmol/L and 9122 IU/d was needed to reach 100 nmol/L.
> This could lead to a recommendation of 1000 IU for children 1 year of age, and around 8000 IU for young adults and thereafter. Actions are urgently needed to protect the global population from vitamin D deficiency.

> Since 10 000 IU/d is needed to achieve 100 nmol/L [9], except for individuals with vitamin D hypersensitivity, and since there is no evidence of adverse effects associated with serum 25(OH)D levels <140 nmol/L, leaving a considerable margin of safety for efforts to raise the population-wide concentration to around 100 nmol/L, the doses we propose could be used to reach the level of 75 nmol/L or preferably 100 nmol/L.
Because it's common to hate on antidepressants, I've always personally had a bias against them. For the past 15-20 years, november thru february are basically a writeoff due for me due to seasonal affective disorder. Cold showers, exercise, no alcohol, strict sleeping rituals. Vitamin d. I can still sleep 11 hours and feel like reheated cat shit. Enter citalopram. "It will take up to six weeks to dial in" they said.…

I found this to be the case. Tried Sertraline for a while, gave me headaches and made me feel sick. Then as part of a new gym plan, started taking Omega 3+VitD daily, and I just felt a sense of calm and peace after a few weeks. The massive uptick in exercise probably also helped. I also felt quite an extreme uptick because I was a vegan for 10 years, and found out I had basically zero Omega 3 in my blood. I suspect o…
> I was a vegan for 10 years, and found out I had basically zero Omega 3 in my blood I see your disclaimer, but just for more context, vegans can get Omega 3 without taking pills per se. Flax seeds are an excellent source. I often add a spoonful to a bowl of oatmeal or as a pancake topping along with fruit sauce and granola.
Just get an algae oil based DHA+EPA supplement.
