New research from Michael Holick indicates that tanning beds may be even more effective at producing vitamin D than was previously believed, according to reports from Smart Tan.
Holick’s group studied 15 people aged 20-53, tracking their vitamin D blood levels as they tanned in tanning equipment three times a week. Fifty percent had higher vitamin D blood levels after one week of tanning and 150 percent had higher vitamin D blood levels after five weeks of tanning.
