I can’t take folic acid (since early 20s) . when I do I feel aggressive, can’t focus and I am very emotional (to the point I can’t work). My doctor said it sounds like an intolerance and to try supplement with food. I’ve also read it can be a sign of low b12 but my doctor didn’t raise b12 level as an issue. It’s difficult to know if I am getting enough. What do others do? All conception supplements, obviously, contain it so I’m not sure what to do. TTC for 3 months. Im extremely run down as my toddler doesn’t sleep well and I’m up at least twice a night and get little sleep (2 years straight) . Not ideal for ttc but clock is ticking. I thought a supplement, as well as concerted effort to walk and get fresh air each day, and eat better may help.
