Folate, also known as vitamin B9, is a crucial nutrient that supports DNA synthesis, cell division and overall health. It is especially important for women of childbearing age, as adequate folate levels help prevent neural tube defects in developing babies during pregnancy.

Normal Folate Levels

Folate levels are measured through blood tests, typically reported in nanograms per millilitre (ng/mL) or nanomoles per litre (nmol/L). For women, a normal serum folate level usually ranges from about 3 to 17 ng/mL (7 to 39 nmol/L), although reference ranges can vary slightly depending on the laboratory and measurement method.

Red blood cell folate levels provide a longer-term view of folate status, with normal ranges often cited as 140 to 628 ng/mL (317 to 1420 nmol/L).

Importance of Maintaining Normal Levels

Maintaining adequate folate levels supports healthy cell function, reduces the risk of anaemia and is vital before and during pregnancy to prevent birth defects. Low folate can lead to fatigue, weakness and increased risk of complications.

Summary

A normal folate level for women typically falls between 3 and 17 ng/mL in serum tests, but ranges vary. Ensuring adequate folate intake through diet or supplements is important for overall health and pregnancy planning.
