1Calculated sunlight exposure time to produce 1000 IU vitamin D in young healthy individuals based on skin type (approximately 500 IU in older adults); 225 Percent BSA is the equivalent to a combination of arms, hands and face; *Two control group participants attended scheduled outdoor activities. No direct sunlight exposure was observed.
