We are TTC as of tomorrow when I get my implant out and will be picking up some folic acid too while I'm at it! But I'm overweight, BMI is above well above 30, I've tried making diet alterations, cutting out sugar, sweets etc and I've gained weight rather than lost!! I'm so disheartened, but my question is has anyone who's overweight been told to take a higher dosage of folic acid? I've seen conflicting evidence, some says you need to take 5mg, some is saying only take more if you've have neural tube defects before, so I don't know what to do. I'll mention it tomorrow at the health clinic but I doubt she will be much help as they normally just want you in and out
