Folic Acid Is the Synthetic Form of Folate.
Folate is found naturally in foods like leafy greens and oranges, but you can get the same benefits from folic acid, a synthetic form of folate that is found in some food and supplements. Unlike folate, folic acid is very stable at high temperatures and under pressure. Folic acid is also more easily absorbed than its natural counterpart. The body can absorb about 85 percent of folic acid compared to around 50 percent of folate. This can make folic acid a better option for restoring low folate levels and preventing folate deficiency in people who are at risk for the condition. While folate is absorbed and activated in the intestines, folic acid is converted to its active form outside of the digestive system, usually in the liver. That means it takes slightly longer for your body to metabolize folic acid, which can build up in the body, potentially causing health problems. Drinking orange juice and taking other B vitamin or vitamin C supplements in combination with folic acid can help your body process folic acid faster.
