Folic acid (Vitamin B9)

Folic acid, Folate, or vitamin B9, is a member of the vitamin B group. Naturally, folic acid is found in beans, peas, lentils, beets, broccoli, spinach, sprouts and liver. It has astonishing effects for both treatment and prevention of megaloplastic anemia. The megaloplastic anemia is very dependent on the folic acid/folate deficiency. That’s the point why many legumes and dark green vegetables are said to help treat megaloplastic anemia. Symptoms of folic acid deficiency include fatigue, growth problems and mouth sores. Megaloplastic anemia symptoms are persistent fatigue, pale skin, lethargy, irritability and diarrhea.

Physiologically, folic acid has a substantial role in some amino acids conversions and metabolism. Also, it is essential for DNA synthesis and production of red blood cells. After eating folate-containing food, it’s promptly absorbed from the proximal part of the small intestine. Folic acid is then distributed to all body tissues. Thereafter, stored in liver and concentrated actively in the cerebrospinal fluid.

P.S. Cerebrospinal fluid is a colorless fluid present in the brain and spine. It’s significance is mainly mechanical and immunological.
