Several experiments in humans and animals which demonstrated a
reduction of Sr uptake when Sr isotopes were administered very early
before or together with alginate, in the majority of the cases via
the oral route. In animals reductions of Sr intake of 1.2 to 10-fold
were measured. The radioactive Sr isotopes were determined in
carcass, skeleton, femur or whole body. In humans reductions in Sr
uptake of 1.6 to 24--fold were reported. Radioactive Sr isotopes
were measured in whole body or plasma (Vanderborght et al. 1971).
