Maternal folate deficiency is also a prenatal and perinatal factor that is a risk factor for autism. Folate (Folic Acid) is a micronutrient that is a type of B vitamin. This nutrient can play a vital role in a uterus’s development and the production of healthy red blood cells. A person can get folate in by eating fruits and vegetables. It was hypothesized that maternal supplementation of folate can help reduce a baby’s risk of developing ASD. Research on the relationship between folate and Autism Spectrum Disorder has had mixed results. Studies conducted by Raghavan et al. (2017) and Levine et al. (2018) found that when a mother was exposed to folate through supplements before and/or during pregnancy, there was a reduced risk of the child having Autism. However, in Egorova et al.’s (2020) study of the biomarkers found in the blood serum samples of mothers of children with Autism, it was found that higher levels of folate were correlated with an increased risk of ASD.
