Vitamin D Research in Antarctica

Vitamin D deficiency that has become an increasing problem as people use sunscreen to prevent skin cancer, however at the same time you end up getting less vitamin d from the sun that is necessary for healthy bones. I just read this article about a research study to determine if vitamin D supplements are effective treatment. It relates to Antarctica as the study is using people who are in Antarctica as the test subjects because with the 24 hour winter darkness it makes the best way to test if the supplements can make up for the lack of vitamin D from sunlight. The research is just starting with those that went down this October, so the results are still unknown. It does sound like something interesting to try to keep up-to-date on, as vitamin D deficiency is an increasing issue to be aware of and learn to avoid.
