Effect of daily supplements of selenium on patients with muscular complaints in Otago and Canterbury.
The alleged beneficial effect of selenium (Se) on fibromuscular rheumatism in residents of low soil-Se areas of New Zealand has been explored. Three dosing trials, two of them double blind trials, using physiological daily supplements (100 micrograms Se) of sodium selenite or selenomethionine and a placebo have been carried out. Blood Se and glutathione peroxidase (EC 1.11.1.9; GSHPX) activities were monitored and clinical assessment of the efficacy of the treatment was made during the trials. Blood Se and GSHPX activities rose in all patients who received Se whereas those in control groups remained more or less constant throughout the study. Clinical assessment of muscular symptoms showed that approximately half of the patients in both trial groups and placebo groups responded to treatment. Thus we have been unable to give conclusive evidence of a response to Se supplementation for relief of muscular complaints.
