But, out of curiosity, Gilroy decided to stop tanning and see how his vitamin D serum level was affected. He stopped indoor tanning after his February test and continued taking a 400 IU supplement every day. He took a walk every morning and only wore sunscreen when necessary to prevent sunburn, like when he played golf or was on a boat. By his next vitamin D test in August, Gilroy’s vitamin D serum level had dropped from 112 nmol/L to 62 nmol/L. Even after going through the sunny summer and spending an average amount of time outdoors, his vitamin D level was cut nearly in half.
“I was interested in finding out how my indoor tanning was affecting my vitamin D level and to see if recommendation from Health Authorities were either correct or not,” Gilroy said. “I did everything else exactly as I normally would.”
After taking up tanning again following that test, Gilroy’s level returned to 122 nmol/L when tested in April 2010. Then, to confirm his finding, Gilroy stopped tanning again. By his next test in September 2010, Gilroy’s vitamin D serum level had again dropped to 70 nmol/L.
Gilroy’s anecdotal evidence backs the findings of multiple published research studies – that indoor tanning is an effective way to maintain optimal vitamin D levels, especially in the spring.
“We’re not saying that indoor tanning is for everybody,” Gilroy says. “But, it is certain that it’s a viable option for raising vitamin D levels, especially given the lack of sunlight that we face in the spring and winter. Everyone should know, you don’t need to get a tan to make Vitamin D from a sunbed that produces UVB light.”
