When should I start taking OBTREX DHA?

Ideally, you’ll begin taking extra folic acid at least 3 months before you become pregnant. Make sure it's a kind of folic acid that's easily metabolized, like the one that’s in OBTREX™ DHA, because proper prenatal nutrition is vital to a baby’s neural development.
However, if you’re already pregnant, don’t stress! You and your baby will benefit from this prenatal any time during your pregnancy.
