For supplementation and treatment, it is available as either of the following: The synthetic form, known as folic acid or pteroylglutamic acid.
Why folic acid is given along with Vit B12?
Vitamin B12 works closely with vitamin B9, also called folate or folic acid, to help make red blood cells and to help iron work better in the body. Folate and B12 work together to produce S-adenosylmethionine (SAMe), a compound involved in immune function and mood.
How does folic acid deficiency cause megaloblastic anemia?
In folate-deficiency anemia, the red blood cells are abnormally large. Such cells are called macrocytes. They are also called megaloblasts, when they are seen in the bone marrow. That is why this anemia is also called megaloblastic anemia.
Why is folic acid important?

Which role does folic acid play in erythropoiesis? Folic acid promotes maturation of RBCs.
Are folic acid and cyanocobalamin interchangeable in the treatment of megaloblastic anemia Why?
Folic acid is not a substitute for cyanocobalamin in the treatment of vitamin B12 deficiency, although it may improve vitamin B12 megaloblastic anemia. However, exclusive use of folic acid in treating vitamin B12 deficient megaloblastic anemia could result in progressive and irreversible neurologic damage.
Why is vitamin B12 deficiency called a megaloblastic anemia?
Either a lack of vitamin B-12 or a lack of folate causes a type of anemia called megaloblastic anemia (pernicious anemia). With these types of anemia, the red blood cells don't develop normally. They are very large. And they are shaped like an oval.
Does folic acid help with B12 deficiency?
Vitamin B12 deficiency produces both an anaemia identical to that of folate deficiency but also causes irreversible damage to the central and peripheral nervous systems. Folic acid will correct the anaemia of vitamin B12 deficiency and so delay diagnosis but will not prevent progression to neurological damage.
What is megaloblastic anemia?
Megaloblastic anemia is a type of anemia characterized by very large red blood cells. In addition to the cells being large, the inner contents of each cell are not completely developed. This malformation causes the bone marrow to produce fewer cells, and sometimes the cells die earlier than the 120-day life expectancy.

Megaloblasts occur when inhibition of DNA synthesis causes asynchronous maturation between the nucleus and the cytoplasm. Clinical manifestations are similar to those of other types of anaemia, with the exception of cobalamin deficiency megaloblastic anaemia, which presents distinctive neurological symptoms.
What are the B vitamins that are essential for cellular processes?
Abstract. Folic acid and cobalamin are B-group vitamins that play an essential role in many cellular processes. Deficiency in one or both of these vitamins causes megaloblastic anaemia, a disease characterized by the presence of megaloblasts. Megaloblasts occur when inhibition of DNA synthesis causes asynchronous maturation between ...
What is the name of the compound that binds to a cyano radical?
Cobalamin is given different names, depending on the radical to which it is bound. When it binds to a cyano radical, it is called cyanocobalamin or vitamin B12, a highly stable compound. Other functional forms of cobalamin include adenosylcobalamin (adenosyl radical) and methylcobalamin (methyl).
What foods contain folate?
It is also found in fruit, such as lemons, oranges, bananas and melons, and in cereals, grains, nuts, beans, beef, fish, liver and kidneys.6 Prolonged storage or over-cooking in abundant water can significantly reduce the folate content of food. 10. Daily adult requirements of folic acid range from 50 to 100 mcg.
Where is folate stored?
Folate is primarily stored in the liver. 12. Folic acid is mainly absorbed in the jejunum by means of passive transport following the concentration gradient, and by means of active transport when folate binds to reduced-folate transporter 1 and 2 (RFT-1 and RFT-2) and folate binding protein (FBP).

Why is folate not taken during pregnancy?
Also, the mother absorbs it more slowly. A lack of folate during pregnancy is linked to major birth defects that affect the brain, spinal cord, and spine (ne ural tube defects). Some babies are born unable to absorb folic acid. This can lead to megaloblastic anemia. With this condition, red blood cells are larger than normal.

Low levels of folic acid can cause megaloblastic anemia. With this condition, red blood cells are larger than normal. There are fewer of these cells. They are also oval-shaped, not round. Sometimes these red blood cells don’t live as long as normal red blood cells.
What causes megaloblastic anemia?
Most, but not all, megaloblastic anemia is produced by "ineffective erythropoiesis" in the bone marrow due to either folic acid or vitamin B12 deficiency. In folic acid deficiency the cause frequently is inadequate dietary intake, whereas vitamin B12 deficiency is almost always conditioned by some specific type of malabsorption.
Is aplastic anemia a bone marrow biopsy?
Aplastic anemia, refractory anemias with cellular marrow, preleukemia, aleukemia, and erythroleukemia may have somewhat similar blood findings but are usually recognizable from bone marrow biopsy.

Can folate be differentiated from vitamin B12?
Differentiation between folate and vitamin B12 deficiency is important but impossible by blood and bone marrow morphology alone. Thus, if serum levels are unavailable, the distinction must be made, sometimes retrospectively, on the basis of other laboratory examinations, such as gastric analysis, small-bowel x-ray films, and the Schilling test.
What is the treatment for megaloblastic anemia?
Once drug-induced megaloblastic changes and myelodysplasia-related megaloblastosis have been ruled out, most patients are treated with cobalamin or folate. Since megaloblastic anemias usually develop gradually, many patients adjust to low hemoglobin levels and do not require transfusions. Transfusion therapy should be restricted to patients with severe, uncompensated, and life-threatening anemia.

Folate is also indicated in patients with chronic hemolytic anemias, psoriasis and exfoliative dermatitis, and during extensive renal dialysis.
Can potassium be taken with iron deficiency?
Therefore, potassium should be monitored and supplements may be indicated. Iron deficiency can occur in the course of treatment due to the consumption of iron stores for red blood cell production.
Can folic acid be used for megaloblastic anemia?
Folate therapy should not be instituted in a patient with megaloblastic anemia if cobalamin deficiency has not been definitively ruled out. The danger is that folic acid will improve the anemia but not the neurological complications of cobalamin deficiency, and the neurological disorder will worsen.
