Hello. I’ve been trying for a baby for 4 years and have been encouraged to take 5 mg by many health professionals for duration. I haven’t stayed on this much of a high dose the whole time but have been on a pretty high dose consistently . I now get panic attacks at night, chest pains, heart palpitations when I take high doses. It’s been quite scary and I’ve now had stuff show up in ecg and am worried it’s potentially damaged my heart. Just wondering if anyone else has had bad reactions to high doses of folic acid? There seems to be a lot of worrying research linked to high doses.
