Details and patient eligibility

About

Iron-deficient anaemic subjects are likely to benefit most from oral iron supplements, but supplementation schedules vary widely in clinical practice, absorption is low and compliance is poor due to mild gastrointestinal side effects. The investigators will compare iron absorption from labeled oral iron doses of 100mg and 200mg administered either on two consecutive days or on alternate days in young anemic women.

Enrollment: 20 patients

Sex: Female

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers

Trial design

20 participants in 1 patient group

Stable isotope labeled iron II sulfate

Description:

All subjects will go through two iron absorption study cycles. In one cycle they get 100mg oral iron labeled with stable isotopes on two consecutive and on one alternate day and in another cycle they get 200mg oral iron labeled with stable isotopes on two consecutive and on one alternate day. Half of the subjects start with the 100mg cycle whereas the other half starts with the 200mg cycle.

Treatment:

Other: Iron stable isotope labeled iron(II) sulfate
