  Purpose
The purpose of this pilot study is to determine whether breast milk retinol concentration increases in response to daily supplementation with small amounts of vitamin A (~600 ug RAE/d), as either a b-carotene or retinyl palmitate, 6 d/week for 3 weeks. A secondary purpose is to evaluate sampling methods for collecting breast milk samples in a community setting. The results of this pilot study will allow us to determine whether milk retinol is a useful indicator for evaluating the impact of food-based interventions on the vitamin A status of lactating women.

Primary Outcome Measures:
  • breast milk retinol concentration [ Time Frame: 3 weeks ]
    breast milk retinol concentration is measured at baseline and after 3 weeks of supplementation with 600 ug RAE/d (as either b-carotene or retinyl palmitate) or 0 ug RAE/d


Secondary Outcome Measures:
  • plasma retinol concentration [ Time Frame: 3 weeks ]
    plasma retinol concentration is measured at baseline and after 3 weeks of supplementation with 600 ug RAE/d (as either b-carotene or retinyl palmitate) or 0 ug RAE/d
