It's not though. That is to say... people really ought to check their blood results and act appropriately. The truth is that in northern latitudes, anyone with dark skin is simply unable to meet their vitamin D intake from sun exposure alone. In certain parts of America, and a lot of Europe, a dark skinned person spending the entire lit part of the day outside buck naked is still not enough to synthesize enough vitamin D to be sufficient. Supplementation or dietary ingestion is necessary. For me, as a dark skinned person in a northern latitude, my levels were very low. Taking 2000 IU a day did nothing. I had to take 10000 IU a day in order to appreciably raise my Vit D levels. That is what we found after checking with a doctor. I would recommend anyone else do the same. 5000 IU + is typical for people with vitamin D deficiencies. Some doctors even recommend extremely high megadoses to reset your vitamin D intake.
