Brief Summary

Iron deficiency problem has always been in Taiwan. This is a randomized, double-blind trial. Subjects separate to 3 groups, one group (n = 20) take two Natureheme-iron capsules a day for a total of 12 weeks, another group (n = 20) with the same dose of placebo, and the other group (n = 20) is a commercial iron supplement. Investigators assess whether Natureheme-iron can promote iron absorption and antioxidant effects, and compare the effects with commercial iron supplement. When this study is completed, it will increase the value of Natureheme-iron, and can improve health of Taiwanese.

Interventions

Natureheme-ironDIETARY_SUPPLEMENT

An 12 week double-blinded randomized parallel study with 4 week follow-up period was performed in mild anemia subjects. Consenting eligible subjects were receive 2 capsules per day containing either 1000 mg Fe of similar appearance for 12 weeks. The subjects were required to visit at baseline, every 6 weeks during the intervention period (6 weeks), and at follow-up 4 weeks after treatment had ended. During each study visit, fasting blood samples were collected and anthropometric measurements were performed. Compliance was evaluated using a food diary and monitored with biweekly telephone calls.
