Summary

The primary objective of this study is to evaluate plasma concentrations of Vitamin D (25-hydroxyvitamin D; 1,25-dihydroxyvitamin D) of different Vitamin D formulations in healthy volunteers at two concentrations. Pharmacokinetic parameters (Serum 25(OH)D and 1,25(OH)2D ng/ml) are compared with those of a regular Vitamin D formulation and a new (microencapsulated) LipoMicel Vitamin D formulation.

The secondary objective of this study is to evaluate safety blood parameters- The following blood parameters (serum levels) are checked: Alkaline Phosphatase, ALT, AST, Bilirubin, CRP, Creatinine, GGT. In addition, mineral levels-such as calcium, magnesium and phosphorus, potassium and sodium-are measured before and at the end of the study.

Conditions

  • Vitamin D

Interventions

DIETARY_SUPPLEMENT

Vitamin D3

Participants are randomly divided into 4 groups. The first group receives regular Vitamin D3 (1000IU), the second receives microencapsulated D3 (1000IU), the third group receives regular Vitamin D3 (2500IU), the fourth receives microencapsulated D3 (2500 IU). Plasma concentrations of Vitamin D (D3, 25(OH)D3 and D2) are measured at baseline-before treatment start (day 0), during treatment (day 14) and at end of treatment (day 30). After the end of supplementation, blood vitamin D concentrations are checked again at day 45 and day 60.
