| Measure | Time frame |
|---|---|
| Main Objective: Primary objective: to evaluate the mean change versus baseline of a monthly administration of 50.000 I.U. 25 hydroxy-Vitamin D, during six consecutive months on plasma levels of Vit D in young healthy volunteers.;Secondary Objective: Secondary objectives: to evaluate the influence of Vit D supplementation on muscle strength, fatigue and infectious episodes frequently encountered during winter (rhinitis, pharyngitis, otitis, Influenza, and G.I. tract infections).;Primary end point(s): The primary efficacy endpoint is the mean change in 25-hydroxy Vitamin D levels between the baseline (D1) and the treatment period (D3). The mean change will be calculated as the ratio R=D3/D1 or its logarithm log (R). The mean changes in 25-hydroxy Vitamin D levels (primary endpoint) in the two study groups (investigational and comparator) will be compared by a two-sided Student t-test at the 5% significance level, based on the ITT population. | — |
