Welcome to HCM.
Folinin contains Methylcobalamine with folic acid
contains zinc with folicacid.
To maintain pregnancy
both drugs are equaly important ...but zinc with folicacid is more important in early pregnancy to prevent Neural tube defect
.Zinc also increases the folicacid uptake. Your doctor is good and on a right way.You can also ask this to your doctor because he/she is now your actual care taker till delivery.Best wishes.
