About
The aim of the study is to determine the factors affecting the bioavailability of iron and folic acid during the simultaneous use of iron supplements and folic acid supplements in non-pregnant women of childbearing age.
Full description
Scientists in the field of nutrition and gynecology and obstetrics have been paying attention to the need of use iron and folate supplements in women of childbearing age. Increased intake of micronutrients in the diet or the use of supplementation does not always bring the expected results, what depends on factors that affect the bioavailability of minerals and vitamins. On the one hand these factors are related to the properties of food intake, e.g. to the presence of other nutrients that can increase or decrease the absorption of folates and iron (eg vitamin C, phytates), and on the other hand the functioning of the body itself, which to a certain extent is determined by genetic factors (e.g., genetically determined reduced activity of methylenetetrahydrofolate reductase [MTHFR], which reduces the bioavailability of folic acid).
The study aims:
assessment of the effect of simultaneous supplementation with iron and folate on:
the estimation of gene polymorphisms encoding proteins transporting iron and folate
obtaining information whether the polymorphism of genes encoding proteins transporting iron and folate is related to the effectiveness of the iron and folic acid supplementation used in non-pregnant women of childbearing age.
In 200 non-pregnant women of childbearing age a blood level of iron and folic acid will be determined. Subjects with low level of blood iron and folic acid will be supplemented with oral iron and folic acid for 3 months. Subjects with proper level of blood iron and folic acid will be a control group. At baseline and at completion of the study (after 3 months) fasting blood will be collected and abovementioned parameters will be estimated.
