[Fractional utilization of reduced iron powder in Chinese child bearing age women with dual stable isotopes].
OBJECTIVE
To study the utilization of reduced iron powder in child-bearing-age women with traditional Chinese food.


METHODS
20 health child-bearing-age women were randomly divided into two groups. With ferrous sulfate as control, the utilization of reduced iron was measured using dual stable isotopes.


RESULTS
The fractional utilization of iron in ferrous sulfate was 5.8%, while in reduced iron powder was 2.1%. The rates of absorbed iron incorporated into hemoglobin were 70.1% and 91.3% respectively. The differences were statistic significant.


CONCLUSIONS
With traditional Chinese food, the utilization of reduced iron in child-bearing-age women was 2.1%, and the rate of absorbed iron incorporated into red blood cells was 91.3%.
