Individual folate values are means of duplicate analyses from duplicate trials (n = 2). The sum of folate was calculated from individual folate forms using the conversion factors 445.4 for tetrahydrofolate (H4folate), 459.5 for 5-methyl-tetrahydrofolate (5-CH3–H4folate), 469.4 for 10-formyl folic acid (10-HCO–PteGlu) and 473.5 for 5-formyl-tetrahydrofolate (5-HCO–H4folate). Different superscripts within the same column represent significant differences (P < 0.05). DM, dry matter.
