Folic acid is LIKELY SAFE for most people. Most adults do not experience any side effects when consuming the recommended amount each day, which is 400 mcg.
High doses of folic acid might cause abdominal cramps, diarrhea, rash, sleep disorders, irritability, confusion, nausea, stomach upset, behavior changes, skin reactions, seizures, gas, excitability, and other side effects.
There is some concern that taking too much folic acid for a long period of time might cause serious side effects. Some research suggests that taking folic acid in doses of 800-1200 mcg might increase the risk of heart attack in people who have heart problems. Other research suggests that taking these high doses might also increase the risk of cancer such as lung or prostate cancer.
Don't take more than 400 mcg per day unless directed by your healthcare provider. |
