Detailed Description
The objective of the present study is to evaluate the non-inferiority of the absorption parameters of three silicon supplements in human volunteers.
Participants: 5 healthy men over 18 years old, with normal serum creatinine levels. Treatment consists of one product consumption every week, and measuring postprandrial response at 0, 30, 60, 90, 120, 180, 240 and 360 min, in blood, and urine in two periods of three hours each.
The statistical analysis will follow the principles specified in the guidelines of the ICHE and CPMP/EWP/908/99 ICHE Points to Consider on Multiplicity Issues in Clinical Trials.

Measure Description |
Time Frame |
---|---|---|
concentration of sillicium in urine samples
Time Frame: Urine will be collected in two 3-h collections (0-180min and 181-360 min) in two separate containers at Visit 1, Visit 2 and Visit 3 (1 week between visits)
|
concentration of sillicium in urine samples will be measured by inductively coupled plasma optical emission spectrometry.

Measure Description |
Time Frame |
---|---|---|
concentration of sillicium in plasma
Time Frame: Blood samples will be collected to determine baseline plasma silicon value (time 0 min = T0). After ingestion of one of the study products, additional blood samples will be collected at 30, 60, 90 and 120 min at Visit 1, Visit 2 and Visit 3
