The status of retinol and vitamin E was evaluated in 69 well-nourished lactating Sudanese women of 2 villages of the irrigated Gezira area. All were consuming local Sudanese food. Plasma retinol, alpha -tocopherol and total tocopherol were estimated by HPLC. Plasma retinol concentrations ranged between 29.19-141.37 micro g/100 ml (mean 63.01 micro g/100 ml). All values were above 20 micro g/100 ml, the lower cut-off point of normal, and revealed a good retinol status. The ratio of total tocopherol/total lipids (mg/g) was 1.35-2.72 and was above the lowest normal ratio of 0.60, indicating an excellent vitamin E status. Neither the retinol nor tocopherol values showed a correlation to parity or duration of breast-feeding.
