As morning sickness becomes a problem in some pregnancies many women do not like taking extra pills. A good option is to take vitamin D drops. The liquid form of vitamin D can be easier to take.
It should also be noted that taking methylated folic acid or methylfolate is advised because the active form is better absorbed by the body.
Adequate folic acid intake is also shown to reduce preterm labor. A study showed that taking folic acid supplements at least a year before pregnancy reduces preterm labor and premature births by at least 50%.
