The objective of this study was to (1) to determine the contribution of moderate sun bed exposure to serum 25(OH)D 3 levels; (2) to estimate the decay time of a high 25(OH)D 3 level obtained by sun bed exposure; and (3) to evaluate if the recommended ingestion of vitamin D is sufficient to maintain the 25(OH)D 3 concentration obtained by sun bed exposure.
