Folate or vitamin B9 is essential for cell growth. Moreover, studies have shown that vitamin B9 helps prevent several birth defects (especially anencephaly and spina bifida). All of these birth defects happen during the first month of pregnancy, hence, it is important for all women of childbearing age to have adequate levels of folate in the diet.
Folate also promotes healthy neural tube formation and adequate birth weight. Pregnant women should get 600 mcg of vitamin B9 daily. 100g of this root contains 57 mcg folate.
Note – supplementation with folic acid (the synthetic form of folate) is linked to many adverse effects, including an increase in the risk of colorectal cancer.
Selenium, discovered as an element in 1817, is a trace mineral which acts as a powerful antioxidant to prevent the formation of free radicals.
