Its symptoms include weakness, fatigue, difficulty concentrating, irritability, headache, heart palpitations, and shortness of breath [2]. Dizziness. Likewise, the authors of the third update of a Cochrane review of the effects of homocysteine-lowering interventions on cardiovascular events concluded that folic acid supplementation alone or in combination with vitamin B6 and vitamin B12 does not affect the risk of myocardial infarction or death from any cause, but it does reduce the risk of stroke [97]. This is because the developing baby needs more folic acid. |Service Is this an emergency? Am J Epidemiol 2013;178:1028-37.

For practical purposes, serum folate is almost entirely in the form of N-(5)-methyl tetrahydrofolate.(1). In some cases, fortified foods and dietary supplements are useful when it is not possible otherwise to meet needs for one or more nutrients (e.g., during specific life stages such as pregnancy).".

People with a genetic polymorphism, 677C>T, in the methylenetetrahydrofolate reductase (MTHFR) gene have a reduced ability to convert folate to one of its active forms, 5-MTHF, because the methylenetetrahydrofolate reductase enzyme needed for this conversion is less active [21].

In most cases, serum folate testing alone is sufficient for assessment of folate status, but if there is strong clinical suspicion of folate deficiency and the serum folate level is normal and cobalamin deficiency has been ruled out, the red blood cell (RBC) folate level may be measured.
