Vitamin A Bioavailability in Lactating Women With Marginal Vitamin A Status

Vitamin A Deficiency Clinical Trial

Official title:
Impact of Daily Feeding of Food Sources of Cryptoxanthin (CX) and Beta-carotene (BC) on Plasma and Breast Milk Concentrations of CX, BC, and Retinol (VA) in Lactating Women With Marginal Vitamin A Status

Clinical Trial Summary

The study will assess the relative bioavailability and bioefficacy of cryptoxanthin (CX) and beta-carotene (BC) from food sources for increasing breast milk carotenoid and retinol concentrations in lactating Bangladeshi women.

Clinical Trial Description

The specific aim is to compare the effects of orange-fleshed sweet potatoes and tangerines compared to white-fleshed sweet potatoes and vitamin A as retinyl palmitate on blood and breast milk cryptoxanthin (CX), beta-carotene (BC), and vitamin A (VA) concentrations by randomly assigning lactating Bangladeshi women to one of four treatment groups for 6 days/week for 3 weeks.

The investigators will also compare the relative vitamin A (VA) value of BC and CX from food sources by comparing the mean change in breast milk retinol concentrations of the groups that receive tangerines (CX) or orange-fleshed sweet potatoes (BC) with the mean change in breast milk retinol of the group that receives retinyl palmitate. ;
