Vitamin D is 100X better than folic acid during pregnancy

Mandatory Folic Acid reduced Spina bifida rate by 1 in 2000 births
Mandatory vitamin D would reduce premature birth: 1 in 10 ==> 1 in 20 births
Thus for 2000 births Folic acid would prevent 1 Spina Bifida birth, but Vitamin D prevent 100 premature births

Note: Premature Birth is the biggest cause the death for children age 0 - 5 years.

Similar lifetime cost (about $700,000 ) of a premature birth and a Spina bifida birth
But 100X more bad births outcomes could be prevented by Vitamin D than by Folic Acid

Folic Acid increases Breast Cancer risk by 20%
Folic Acid increases colorectal cancer by 35%
Folic Acid increases risk of childhood asthma by 26%
Folic Acid 43% more likely to die from cancer.
Folic Acid, then 30 years later twice as likely to die from breast cancer
Folate was proven to reduce NTD, not Folic Acid

“However, it is estimated that only 15 to 25 percent of folic acid–preventable spina bifida and anencephaly worldwide is being prevented through folic acid supplementation and food fortification programs”

the correct form of what your body needs is folate
While folic acid can be converted by the body to a usable form of folate, the conversion process is limited and this frequently leads to excessive levels of unmetabolized folic acid in the blood (this is unhealthy). Furthermore – and incredibly importantly – folic acid cannot cross the placenta to the foetus, the way natural folate can.

Folic acid does prevent neural tube defects, but doesn’t have the other beneficial effects of natural folate.
