The intestinal absorption of seaweed minerals (Ca, Zn, Fe) was compared with their inorganic salts, in vivo, using a perfused intestinal loop in the rat. A similar uptake of Ca from both sources was observed (19.1±21.0 vs 9.9±14.7 μmol/cm/min, NS), (mean±1 SD), as for Zn (38.8±26.5 vs 47.4±35.0 μmol/cm/min, NS) seaweed Fe absorption was lower than gluconate Fe (26.4±27.7 vs 76.8±7.6 nmol/cm/min, p<0.001). The overall intestinal uptake of these minerals could be explained by their biological form.
