Looking at TTC (trying to conceive) soon, trying to loose weight but it's not happening easily..5ft 3, 12st BMI 30, size 14+ (Not quite a 16)... Question is, after reading lots of threads lots of overweight people are told by g.ps to get a high dose Folic Acid supplement. My doctor however says it's not necessary? Are they right, if you're a gp or midwife would you agree or disagree with them?
