Translations:Vitamer/5/en

Folic acid, a vitamer of vitamin B₉ commonly added to fortified foods and dietary supplements, is 1.7 times more bioavailable than vitamers of vitamin B₉ found in minimally processed foods. Differences in digestion and absorption account for the notable differences in bioavailability between vitamers of vitamin B₉. Forms of vitamin B₉ that occur in minimally processed foods, sometimes referred to as "food folates", require digestion by enzymatic hydrolysis prior to absorption whereas folic acid does not.
