Enhanced bioavailability of iron from spray dried whey protein concentrate-iron (WPC-Fe) complex in anaemic and weaning conditions

The lower bioavailability of iron from the diet has led to iron deficiency and several ill-effects on health. The objective of this study was to assess the bioavailability of iron from spray dried whey protein concentrate-iron (WPC-Fe) complex in weaning and anaemic rats. Blood hemoglobin level, bioavailability, lipid profile, antioxidant status and concentration of iron delivery molecules were analysed under in vivo conditions. Hemoglobin level, % apparent digestibility coefficient and % retention/intake were increased in weaning and anaemic rats on 7th and 28th days. Additionally, WPC-Fe supplementation reduced nitric oxide (NO) production, maintained serum triglycerides, total cholesterol, LDL, VLDL and HDL-cholesterol. Simultaneously, it decreased the superoxide level and lipid peroxidation and increased the catalase activity. The level of iron delivery/transport molecules including liver and serum ferritin and transferrin concentration was enhanced. Thus, WPC-Fe complex could be a better and innovative organic iron fortificant with enhanced bioavailability of iron.
