Vitamin B9 is also known as folate or folic acid. It is a water-soluble vitamin that plays a crucial role in various biological processes. Here are some important aspects of Vitamin B9:
DNA Synthesis and Repair: Folate is essential for the synthesis and repair of DNA. It plays a crucial role in cell division and growth. This is particularly important during periods of rapid cell division and growth, such as during pregnancy and infancy.
Red Blood Cell Formation: Folate is involved in the production of red blood cells (erythropoiesis). It works together with Vitamin B12 to ensure the proper formation and maturation of red blood cells, which are essential for oxygen transport in the body.
Neural Tube Development: Adequate folate intake is critical during early pregnancy to prevent neural tube defects in the developing fetus. Neural tube defects can affect the development of the brain and spinal cord. For this reason, many countries recommend folic acid supplementation for women of childbearing age.
Amino Acid Metabolism: Folate is involved in the metabolism of certain amino acids, including the conversion of homocysteine to methionine. Elevated levels of homocysteine are associated with an increased risk of cardiovascular disease, and sufficient folate intake helps regulate these levels.
Sources: Good dietary sources of folate include green leafy vegetables (such as spinach and broccoli), legumes (like lentils and chickpeas), nuts, seeds, liver, and fortified cereals. Folic acid, the synthetic form of folate, is used in many supplements and fortified foods.
Recommended Daily Allowance (RDA): The recommended daily intake of folate varies by age, gender, and life stage. Pregnant women, for example, typically require higher amounts. The RDA is usually expressed in micrograms of dietary folate equivalents (DFE).
Deficiency: Folate deficiency can lead to megaloblastic anemia, characterized by larger-than-normal red blood cells. It can also result in other symptoms such as fatigue, weakness, and irritability. In pregnant women, folate deficiency is associated with an increased risk of neural tube defects in the developing fetus.
Supplementation: Folic acid supplements are commonly recommended for women planning to become pregnant and during early pregnancy to reduce the risk of neural tube defects. Individuals with certain medical conditions or those taking specific medications may also require supplementation.
Folate vs. folic acid
The terms folate and folic acid are often used interchangeably, but are actually different forms of vitamin B9. The three main types are:
Folate occurs naturally in food and refers to all forms of vitamin B9, including folic acid.
Folic acid is a synthetic (artificial) form of B9 that’s found in supplements and fortified foods. In 1998, the U.S. required that folic acid be added to certain grains (rice, bread, pasta and some cereals) to ensure adequate public intake. Your body needs to change (convert) folic acid into another form of folate before it can be used for nutrition.
Methylfolate (5-MTHF) is a natural, easier-to-digest form of vitamin B9 supplement than folic acid. Your body can immediately use this type of folate.
It’s important to note that folate is sensitive to heat and light, so cooking methods that preserve folate-rich foods can help maintain their nutritional value. As with any nutrient, it’s crucial to achieve a balance through a varied and balanced diet unless specific health conditions or life stages require supplementation.
