Table 4.

Concentration of plasma Zn (ZnPlas) and erythocyte Zn (ZnEryt) for different sources of Zn: fortified rice (Ultra Rice^®) or ZnCO₃.

Source	ZnPlas (μg/mL)	ZnEryt (μg/gHb)
UR^®	77.71 ± 25.17 ^a	32.09 ± 12.92 ^a
ZnCO₃	98.05 ± 37.66 ^a	29.68 ± 17.79 ^a

Results expressed in mean ± standard deviation of variables of rats after 42 days of diet containing 50% or 100% of zinc recommendations for animals, from zinc oxide; test diet = fortified rice or control diet = zinc carbonate, (n = 10 rats/group). Means followed by the same letters in columns do not differ at 5% probability by analysis of variance (ANOVA).
