Summary Vitamin D vs Folic Acid
| Supplement | Number needed to treat (Eliminate one birth problem) |
Lifetime cost of each problem |
Total costs saved for 2,000 pregnancies |
| Folic acid | NNT = 2000 - Spina bifida | $700,000 | $700,000 |
| Vitamin D | NNT = 20 - Premature birth | $700,000, Ref2 | 70,000,000 just preterm births |
