I understood that dietary Vitamin D isn't well absorbed and is of limited benefit in high quantities -
It's far better to get daily sunlight, even in Northern climes.

- MikeCapone 13y agoVitamin D is well absorbed if you take it in gelcap form, as it's fat soluble. Many people take it from "dry" tablets and that's why it's not well absorbed. This can be verified with blood tests.
- lilkevvers 13y agoHaving a substance in your blood doesn't imply that your body is benefiting from it, or even using it.
- MikeCapone 13y agoNo, but it's better than not having it even get to your blood, especially if you test for the bio-available compound in the blood.
- DanBC 13y agoNorthern climes don't get enough sun. Vitamin D supplements (at normal daily doses) are recommended. This is especially important for pregnant women and children under 5. Also for people with limited access to sun ('cultural dress' for example.)
- draugadrotten 13y agoSomali women are dressed in all-over black covers, and as a consequence, there is even something called "the Swedish disease" among Somali immigrants to Scandinavia. It's autism and there is a suspected link with vitamin D deficiency. http://www.thelocal.se/32862/20110328/ http://www.thelocal.se/32862/20110328/ http://www.scientificamerican.com/article.cfm?id=vitamin-d-and-autism http://www.scientificamerican.com/article.cfm?id=vitamin-d-a...
- oblique63 13y agoIt shouldn't be a problem if you have enough vitamin K in your diet: http://articles.mercola.com/sites/articles/archive/2011/03/26/the-delicate-dance-between-vitamins-d-and-k.aspx http://articles.mercola.com/sites/articles/archive/2011/03/2...
- Retric 13y agoSunlight comes with increased cancer risks so even if it's more efficient and cheaper than D it's not nessisarily better. Also, studies have demonstrated that eskimos get significant quantities do D from there diet so diet can work.
- jjindev 13y agoI met a doctor recovering from a very bad breast cancer. Her opinion, for what it's worth, was "get lots of sun, and inspect for skin cancers - they are easy."
- earh 13y agoWhat does "easy" mean? Easy to get melanoma and die?
- andrewcooke 13y agoyou can balance both. the amount of sun you need is quite limited, apparently. see http://www.nhs.uk/Livewell/Summerhealth/Pages/vitamin-D-sunlight.aspx http://www.nhs.uk/Livewell/Summerhealth/Pages/vitamin-D-sunl...
- stonemetal 13y ago15 min, 3 times a week is enough to give you all the D you need. Not nearly enough sun to worry about skin cancer.
- paul_f 13y agoVitamin D is critical to health and should be called something else, not a vitamin. BTW, as you get older, your body loses the ability to convert sunlight to Vitamin D. Of course no one who reads HN would have this issue :-)
- DanBC 13y agoAll vitamins are crucial to health.
- gbog 13y agoBut less crucial than a normal diet. I mean a diet consisting of a little piece of meat with fat bought on the market, cooked at home with some fresh vegetables, etc. Etc.
- DanBC 13y agoWhat? I don't understand what you mean. What do you mean by "vitamins"? That little bit of meat and vegetables will contain vitamins. Those vitamins are a crucial part of a normal diet.
