Can high levels of folic acid from folic acid supplements cause heart palpitations? Can taking vitamin B6 and folic acid together cause such side effects?
I started taking a supplement with high amounts of folic acid and vitamin B6 last week. Sometimes I get heart palpitations, I'm not sure if it's the folic acid. I thought that excess folic acid is excreted through urine so it never occurred to me that a lot of folic acid could cause problems.
