The Importance of Folate
Folate, a water-soluble B vitamin, is crucial for numerous bodily functions. It's essential for cell growth, DNA synthesis, and helps the body create new proteins. Adequate folate intake is particularly important during periods of rapid growth, such as pregnancy, to prevent neural tube defects. It also works with other vitamins, like B12, to prevent anemia. Elevated levels of the amino acid homocysteine have been associated with an increased risk of cardiovascular disease, and folate helps break down this compound.
