    Summary

    Pregnancy leads to a gradual vitamin B6 deficiency, impacting fetal growth. Supplementing vitamin B6 during pregnancy is essential for healthy birth weights.

    Area of Science:

    • Biochemistry
    • Nutritional Science
    • Maternal-Fetal Medicine

    Background:

    • Vitamin B6 (pyridoxine) is crucial for fetal development.
    • Maternal vitamin B6 status can influence pregnancy outcomes.
    • Biochemical changes during pregnancy may affect nutrient levels.

    Purpose of the Study:

    • To assess vitamin B6 status throughout pregnancy.
    • To investigate the relationship between maternal vitamin B6 levels and fetal growth.
    • To identify mechanisms of vitamin B6 depletion during gestation.

    Main Methods:

    • Serum pyridoxal phosphate levels were measured in 16 healthy pregnant women.
    • Measurements were taken from the second trimester until term.
    • Correlations between vitamin B6 status and newborn birth weight were analyzed.

    Main Results:

    • A gradual decrease in serum pyridoxal phosphate was observed during pregnancy.
    • The most significant decline in pyridoxal phosphate coincided with rapid fetal growth.
    • Maternal vitamin B6 status and its decrease correlated positively with birth weight.

    Conclusions:

    • Active transport of pyridoxal phosphate to the fetus is a primary cause of maternal deficiency.
    • Maternal vitamin B6 deficiency during pregnancy is biochemically evident.
    • Vitamin B6 supplementation during pregnancy is recommended.
