Effect of Small Daily Doses of B-carotene on Breast Milk Retinol

Not Applicable
Completed
Conditions
Vitamin A Status
Interventions
Dietary Supplement: placebo
Dietary Supplement: retinyl palmitate
Dietary Supplement: b-carotene
Registration Number
NCT01803659
Lead Sponsor
University of California, Davis
Brief Summary

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.
