I knew folic acid was important, but didn't realize that there seems to be a link in taking higher doses to prevent Down Syndrome.
I've been taking a prenatal vitamin, but even higher doses sound like a good idea. I'm now 3 weeks past conception. Anyone know if high doses might still prevent DS or would it now be too late?
A higher dose of folic acid can't remove an extra chromosome (at best, it may reduce your risk of having a reproductive cell split asymmetrically in the first place), so I don't think that increased doses of folic acid during pregnancy would reduce your risk of having a child with down's.
So interesting that those chromosomal changes can occur even after conception.
