Folic acid works in conjunction with B12 for DNA synthesis. Folic acid deficiency causes macrocytic anemia but never neurologic deficits. Common causes of folic acid deficiency incluhttp://wellinthishou...xplained/6150/e poor diet and alcoholism. Since January 1998, the US Food and Drug Administration has required all enriched cereal/grain products to be fortified with folic acid, with the goal of reducing neural tube congenital defects. Nutritionists have expressed concerns that folic acid fortification masks B12deficiency, and a 2007 study demonstrated cognitive impairment in patients with high folate status in the presence of low B12. These patients were anemic without macrocytosis.The authors suggest that excess folic acid precipitates both hematologic and neuropsychiatric manifestations of B12deficiency. Interestingly, folic acid conferred cognitive protection in the presence of normal B12 levels. The point here is that folic acid supplementation in the presence of B12deficiency may actually aggravate neurological symptoms.
My folate levels are very high!!! A year ago I was doing a resesrch about thing called MTHFR gene mutation, not sure if you have heard about it before? It is diagnosed through genes. Have a look at this, it might be very helpful for all of you too:
What I also read, that people who usualy have MTHFR might have hig numbers of folate in their blood, as simple folate is not used by the body do to MTHFR mutation..
My levels are > 24 very above the norm. 3-17 ..
