Treatment with folic acid plus vitamin B12 reduced homocysteine concentrations by 36% but did not improve cognitive function. The same thing happened to my daughter, she has had high B12 without supplementation. It can also cause megaloblastic anemia. Hereof, how long does it take to correct folic acid deficiency? For folate deficiency anaemia - treatment is usually for 4 months. But if the cause of your folate deficiency anaemia does not change or go away, you may have to take folic acid for longer, possibly for the rest of your life. Your healthcare provider will figure out the best treatment based on: You may need to take folic acid supplements for at least 2 to 3 months.

The authors of a systematic review and meta-analysis of three trials of 5-MTHF (<15,000 mcg/day in one trial, and 15,000 mcg/day in two trials) in combination with fluoxetine or other antidepressants, concluded that 15,000 mcg/day 5-MTHF might be an effective adjunct to SSRI therapy in patients with major depressive disorder, although they noted that this conclusion was based on low-quality evidence [127]. As the initial test, ruling out cobalamin deficiency is very important because deficiency of folic acid and vitamin B12 produce overlapping neurologic manifestations, and both cause megaloblastic anemia, but folate treatment will not improve neurologic abnormalities due to cobalamin deficiency. Some dietary supplements also contain folate in the monoglutamyl form, 5-MTHF (also known as L-5-MTHF, 5-methyl-folate, L-methylfolate, and methylfolate).

Plasma homocysteine concentration is a commonly used functional indicator of folate status because homocysteine levels rise when the body cannot convert homocysteine to methionine due to a 5-MTHF deficiency [9]. A folate level of 18.5 is generally considered normal, with over 20 being considered high. In addition, evidence-based guidelines from the British Association for Psychopharmacology [129] and the Canadian Network for Mood and Anxiety Treatments [130] state that 5-MTHF might be effective as an adjunct to SSRI treatment for depressive disorders.
