Folate belongs to the B vitamin family and is one of the most important vitamins for pregnancy and overall health. It plays a key role in DNA formation, cell development, the prevention of birth defects, and neurological health.
What is folate, and why is it so important?
Folate is the natural form of folic acid. In the body, it plays a role in:
- DNA Regulation
- Formation of Red Blood Cells
- Tissue Growth
- Cell and Embryonic Development
- Brain function (memory, learning, and behavior)
Folate deficiency has been linked to:
-
- Neurological and Memory Problems
- Chronic inflammation
- Depression
- Cardiovascular Diseases
- Infertility and Miscarriages
- Increased risk of cancer
It also works in conjunction with B vitamins (B6 and B12) to regulate homocysteine, a marker associated with heart disease.
