VITAMIN D SUNLIGHT & TANNING BEDS

Supplements and diet, and not sunlight, should be your source of Vitamin D, Dermatology experts have concluded. U.K. researchers proposed 10 to 15 minuets unprotected sun exposure as a good source of vitamin D. Other researchers differ. Studies have shown that sunshine levels in some northern countries are so weak during winter months that the body makes no vitamin Dat all, leading some to estimate half of the population have insufficent or deficient levels of the vitamin, prompting some to recommend tanning beds. Researchers commented on societys where life expectancey has doubled & 30 % of caucasians will develop skin cancer. " Fortunately, there is a non-carcinogenic alternative -- intestinal absorption of vitamin D, fortified foods and / or dietary supplements". said researchers---- Wolpowitz and Gilchrest , Boston University Of Medicine
