The news agency quoted Dr. Carsten Geisler of Copenhagen University's department of international health, immunology and microbiology, who led the study: "When a T cell is exposed to a foreign pathogen, it extends a signaling device or 'antenna' known as a vitamin D receptor, with which it searches for vitamin D. This means the T cell must have vitamin D or activation of the cell will cease. If the T cells cannot find enough vitamin D in the blood, they won't even begin to mobilize." This finding unlocks the mechanism behind what many vitamin D advocates have promoted for a long time: That the Sunshine Vitamin is key to proper immune health, and that natural levels of vitamin D are only indigenous in those who live and work outdoors, getting plenty of sunshine. “Most Vitamin D is made by the body as a natural by-product of the skin's exposure to sunlight. It can also be found in fish liver oil, eggs and fatty fish such as salmon, herring and mackerel, or taken as a supplement,” Reuters reported, acknowledging what Sunshine Vitamin advocates understand, “Almost half of the world's population has lower than optimal levels of vitamin D and scientists say the problem is getting worse as people spend more time indoors.” To read the Reuters report click here.https://smarttan.com/blog/wp-content/uploads/2010/03/2010-03-09-D-link-to-Immune-System-Unlocked-copy.jpg
