Nutrient Key Information | |||
Nutrient Name: | Folate, total (Vitamin B-9) | ||
Nutrient Category: | Vitamins and Other Components | ||
Measuring Unit: | µg | ||
Nutrient Summary: | Folate is also called Vitamin B9. It functions as a coenzyme in the synthesis of nucleic acids (DNA and RNA) and metabolism of amino acids (Protein). Body needs folate to make DNA, and to make cells to divide. | ||
Nutrient Function: |
Folate includes: 1. Food folate: naturally occurring form of folates in food. Its chemical structure contains up to 6 glutamate molecules (polyglutamate) 2. Folic acid or synthetic folate: the folate in fortified foods and dietary supplements contains 1 glutamate molecule (monoglutamate) Food folate is about 50% lower bioavailable than folic acid. The recommended daily value for folate uses DFE which stands for Dietary Folate Equivalents. DFE is the amount in Food Folate form. DFE value listed in the food label has been adjusted for the differences in the absorption of food folate and folic acid. • DFE = number of μg in food folate • DFE = 1.7 x number of μg in folic acid When folate is absorbed from foods or supplements, it is in the Inactive form (has a CH3 attached). Vitamin B12 removes CH3 from folate and attaches it to itself to activate itself and the folate. Now both folate coenzyme and vitamin B12 coenzyme are available for DNA synthesis. As a B vitamin, Folate is water-soluble. Body stores about half folate in the liver and the remainder in blood and body tissues. |

Additional Nutrient Information | |
Nutrient Summary | Folate is also called Vitamin B9. It functions as a coenzyme in the synthesis of nucleic acids (DNA and RNA) and metabolism of amino acids (Protein). Body needs folate to make DNA, and to make cells to divide. |
Deficiency Health Effects |
Folate deficiency impacts the replacement of red blood cells and GI tract cells. Red blood cells replacement or multiplication failure: chronic inadequate folate intake results in macrocytic anemia. At first, erythrocyte count gets lower, and then hematocrit and hemoglobin value get lower. Moderate to severe macrocytic anemia may have the symptoms: • Weakness and fatigue • Difficulty in concentrating and mental confusion • Irritability and depression • Headache • Shortness of breath GI tract cells replacement failure: folate deficiency impacts the replication of cells lining the GI tract which can cause GI tract deterioration and failure to absorb other nutrients. Notes: 1. Coexisting deficiencies of folate and iron or vitamin B12 may interfere with the diagnosis of their deficiencies because all of them may lead to hematological changes. 2. Some medicines may interfere with the body’s folate function. |
Effects if Above Upper Limit |
The Upper Limit value of folate does not include naturally occurring food folate. And no adverse effects have been associated with the excess consumption of the amounts of folate normally found in fortified foods. Excess folate from supplement may obscure and potentially delay the diagnosis of vitamin B12 deficiency which can result in an increased risk of progressive and unrecognized neurological damage. Large doses of folate supplements might also worsen the symptoms of vitamin B12 deficiency. |
