Hi,
I've repeatedly read on here that you should take more folic Acid if you're over a certain BMI. That's definitely me 
When I spoke to the GP when TTC, she had never heard of this. I'm now 4+5 and would like to ask them again as I don't want to risk anything.
I can find lots of people discussing it online, but no actual official guidelines on this. I'd quite like to go with something official when seeing them next. Does anyone know where that guidance comes from?
Thank you!
