Study Arms:
- Study Group (Type: EXPERIMENTAL): Participants received single, high, oral dose of vitamin D3 (120,000 IU), serum 25(OH)D3, 25(OH)D2, 24,25(OH)2D3, 3-epi-25(OH)D3, 1,25(OH)2D3, 24,25(OH)2D3/25(OH)D3 ratio, and 25(OH)D3/3-epi-25(OH)D3 ratio concentration (measured by LC-MS/MS) at baseline, 3 days and 7 days after bolus dose were measured.~The percentage of fat tissue was determined using Dual-Energy X-Ray Absorptiometry (DXA).
- Control Group (Type: NO_INTERVENTION): Serum 25(OH)D3, 25(OH)D2, 24,25(OH)2D3, 3-epi-25(OH)D3, 1,25(OH)2D3, 24,25(OH)2D3/25(OH)D3 ratio, and 25(OH)D3/3-epi-25(OH)D3 ratio concentration (measured by LC-MS/MS) were measured at baseline, 3 days and 7 days after.~The percentage of fat tissue was determined using Dual-Energy X-Ray Absorptiometry (DXA).

Based on this trial design, predict the completion outcome and termination type (if applicable).
