fólínsýru

Fólínsýru, also known as folic acid, is a water-soluble B vitamin that plays a crucial role in various physiological processes within the human body. It is essential for the synthesis of DNA and RNA, which are the building blocks of genetic material. Folic acid is particularly important during periods of rapid cell division, such as pregnancy, when it helps prevent neural tube defects in the developing fetus. It also aids in the production of red blood cells and the metabolism of amino acids.

Folic acid is found naturally in certain foods, including leafy green vegetables, citrus fruits, and legumes. It can also be obtained through dietary supplements and fortified foods. The recommended daily intake of folic acid varies depending on age and sex, but it is generally recommended that adults consume at least 400 micrograms per day. Pregnant women are advised to consume 600 micrograms per day to ensure adequate levels for fetal development.

Deficiencies in folic acid can lead to various health issues, including anemia, fatigue, and an increased risk of certain cancers. However, excessive intake of folic acid can also be harmful, particularly in individuals with certain medical conditions, such as kidney disease or those taking specific medications. It is important to consult a healthcare provider before starting any new supplement regimen.

Folic acid is a vital nutrient that supports numerous bodily functions. Ensuring an adequate intake through a balanced diet or supplements can help maintain overall health and well-being.
