Plasma tocopherol and tocopherol to lipid ratios in a normal population of infants and children.
The plasma tocopherol concentrations were measured by HPLC in 73 apparently healthy West German children aged from 1 to 14 years and in 7 cord blood samples and 5 infants below 1 year of age. Total tocopherols ranged from 584 to 2024 micrograms/dl in the children above 1 year of age (mean 1046 +/- 283 micrograms/dl) and from 511 to 1155 micrograms/dl in the infants below 1 year of age (mean 879 +/- 270 micrograms/dl). The total tocopherol/total lipid ratio-representing the reliable index for vitamin E status-was far above 0.6 mg/g lipid, a level which is regarded as the lower limit of normal (range 1.23 to 4.09 mg/g total lipid in the older children and 1.52 to 2.05 in the infants below 1 year). A positive correlation was found between plasma lipids and total tocopherol (r = 0.71). Our investigation demonstrated an excellent vitamin E status in the children investigated which is considered to reflect the high supply of West German food with PUFA and vitamin E.
