Selenium supplementation does not alter platelet activation in subjects with normal selenium status.
The effect of Se supplementation on the plasma concentrations of platelet specific proteins, beta-thromboglobulin (beta TG) and platelet factor 4 (PF4), was determined in twenty young women with normal selenium (Se) status using a double blind protocol. Selenium supplementation for 4 weeks (150 micrograms/day), did not elevate the initial mean plasma Se level 95 +/- 4 ng/ml above this level, nor did it alter the plasma beta TG/PF4. Moreover, all the other parameters of the body antioxidative status (plasma alpha-tocopherol, retinol and uric acid and whole blood glutathione) measured in this experiment stayed unaltered during the 4-week supplementation period. The results indicate no relationship between Se supplementation and platelet function in subjects with normal Se status.
