Just after my first miscarriage last year I was diagnosed with B12 deficiency. Doctor said it was not a factor in the miscarriage. However, I’m currently reading the book ‘It starts with the egg’ which states that ‘a deficiency in B12 causes the amino acid homocysteine to build up in the body, which in turn reduces the number and quality of eggs, and that high homocysteine levels have been linked to high rate of miscarriage’.
Over the last year I have continuously monitored my levels, and paid privately for injections (NHS gave me initial injections but wouldn’t continue injections as, although I was still below the recommended threshold I wasn’t apparently low enough below it to qualify!) thankfully my levels have increased hugely so I’m hoping this helps my egg quality.
I’d be really interested if anyone has any thoughts on B12 being linked to miscarriage or has any success stories once b12 was increased?
