Evaluation of Iron Bioavailability From Iron Chlorophyllin

Sodium Iron Chlorophyllin, whose bioavailability is to be studied

Sodium Iron Chlorophyllin and ascorbic acid. The ascorbic acid should not have an effect on Sodium Iron Chlorophyllin

Ferrous sulfate serves as a positive control, whose iron bioavailability is known

Ferrous sulfate serves as a positive control and the addition of ascorbic acid, further enhances its bioavailability

Chlorophyllin with an empty porphyrin ring, given along with FeSO4 to study if there is an incorporation of Fe into the porphyrin ring as it passes the gastric system

Chlorophyllin with an empty porphyrin ring, given along with FeSO4 to study if there is an incorporation of Fe into the porphyrin ring as it passes the gastric system. Ascorbic acid is given along with the intervention to see if there is any difference in the fractional iron absorption when compared to EP+ FeSO4
