Been diagnosed with folic acid deficiency. Been put on folic acid 5mg daily. Whats caused it? How long to feel benefits? And what benefits will I have?

Folic acid anemia. Folic acid is a nutrient substance necessary for the normal development of red blood cells which carries oxygen throughout the body. It often takes up to 3 months to see a significant blood test difference in treatment and you will note less fatigue by that time as well.
