A serum folate level of less than 7 nmol/L (3 μg/L) is indicative of folate deficiency; Red blood cell folate testing is not routinely performed, since serum folate is sufficient in most cases, however, if there is a strong suspicion of folate deficiency despite a normal serum folate level, a red cell folate test may be performed.
A serum folate of 3 μg/L or lower indicates deficiency. [98] Serum folate level reflects folate status, but erythrocyte folate level better reflects tissue stores after intake. An erythrocyte folate level of 140 μg/L or lower indicates inadequate folate status. Serum folate reacts more rapidly to folate intake than erythrocyte folate. [113]
This requires active folate and vitamin B 12, in order to donate a methyl group. Active folate is known as 5-methyltetrahydrofolate (5-MTHF). Another pathway for the conversion of homocysteine back to methionine also exists, involving methylation with trimethylglycine (also called betaine or abbreviated to TMG) as a methyl donor.
Diet improvement is a way to combat nutritional anemia and this can be done by taking dietary supplements such as iron, folate, and Vitamin B12.[2] These supplements are available over-the-counter however, a doctor may prescribe prescription medicine as needed, depending on the patient's health needs.
The un-methylated form, folic acid (vitamin B 9), is a synthetic form of folate, and must undergo enzymatic reduction by dihydrofolate reductase to become biologically active. [1] It is synthesized in the absorptive cells of the small intestine from polyglutamylated dietary folate. It is a methylated derivative of tetrahydrofolate.
They also have a substantial vitamin content — we’re talking vitamins A, B1, B2, B9 (folic acid), C and niacin (B3). What’s more, fenugreek herb contains antioxidants and amino acids.

For example, B 9 is folic acid and five of the folates are in the range B 11 through B 16. Others, such as PABA (formerly B 10 ), are biologically inactive, toxic, or with unclassifiable effects in humans, or not generally recognised as vitamins by science, [ 82 ] such as the highest-numbered, which some naturopath practitioners call B 21 and B ...
