Comparing a Novel Phototherapy Kiosk to Oral Vitamin D Supplementation
Comparing a Novel Phototherapy Kiosk to Oral Vitamin D Supplementation
NCT ID: NCT04556136 Phase: NA Status: COMPLETED Enrollment: 106 Completion: 2019-04-01
Conditions
Hypovitaminosis D
Interventions
Standing Phototherapy Kiosk, D3 Oral supplement
Summary
The purpose of this project is to demonstrate the capability of a standing phototherapy kiosk (SPK) to stimulate cutaneous vitamin D3 and subsequent production of 25 Hydroxyvitamin (OH) D safely and as efficiently as an oral vitamin D3 supplement of 600 IU taken daily over a 10 week intervention period. We will conduct a randomized controlled trial with two treatment arms; \~120 volunteers will be assigned to either the SPK or to a 600 IU daily oral vitamin D3 supplement for 10 weeks. The SPK is an innovative, networked, self-care technology that stimulates endogenous vitamin D production with two \~2-minute treatments per month. It will be tested in an ambulatory setting where enrolled/assigned participants of various baseline levels of 25(OH)D will present for a treatment dose, based on Fitzpatrick skin type category, every other week for 10 weeks. The SPK does not produce a cosmetic tan or dispense pills.
Primary Outcome
Serum Vitamin D Level
