Folate is the vitamin found in the green leafy vegetables. Its synthetic form can be found in the fortified foods and is famous as Folic acid. Deficiency of Folate might cause hyperhomocysteinemia. This is the condition from which almost 5 percent of the population is suffering. It is associated with the enhanced risk of the cardiovascular, type 2 diabetes, neurodegenerative diseases, autoimmune disorders, osteoporosis, renal disease, cancer, anaemia and neuropsychiatric disorders. Folate is also the precursor for many nucleotides and amino acids which in turn are the building blocks of the DNAs and proteins.
