What does a low reading of folate serum mean?

A low reading of folate serum indicates a deficiency in vitamin B9, which is essential for DNA synthesis, red blood cell formation, and overall cellular function. This deficiency can lead to anemia, fatigue, and increased risk of certain health issues, such as neural tube defects during pregnancy. It may also be indicative of poor dietary intake, malabsorption issues, or certain medical conditions. Addressing low folate levels typically involves dietary changes or supplementation.
