Lactating Canadian women consuming 1000 g folic acid daily have high circulating serum folic acid above a threshold concentration of serum total folate. Food folates are in the tetrahydrofolate (THF) form and usually have additional glutamate residues, making them polyglutamates [1].

There has been considerable interest recently in the importance of folic acid as a nutrient. This polymorphism results in less biologically available 5-MTHF and, thus, reduced methylation potential, leading to elevated homocysteine levels and an increased risk of NTDs [1,3,20,40]. Intakes of folic acid that exceed the bodys ability to reduce it to THF lead to unmetabolized folic acid in the body, which has been linked to reduced numbers and activity of natural killer cells, suggesting that it could affect the immune system [5,155]. 1 doctor answer 1 doctor weighed in The authors of a 2017 systematic review concluded that folic acid supplementation protected users from NTDs in studies conducted before food fortification with folic acid began in the United States [142]. 0000114923 00000 n
