In the course of 1 year supplementation trial, most of supplemented elderly persons reached the level of 80–90μg Se/l of serum, which is considered as nearly optimal for safeguard of full functions of selenium in the organism. The level of urine selenium increased to 25–30–90μg Se/l, which is also adequate. Optimum levels were reached within 4 months of supplementation with dose 50–90μg Se/day.
