If you are planning to breastfeed, TheraNatal Lactation Complete is specifically formulated to meet your unique nutrients needs while breastfeeding. If you will be breastfeeding for at least several months, it is better to switch to TheraNatal Lactation Complete while breastfeeding instead of continuing with TheraNatal Complete.

If you are NOT planning to breastfeed, we recommend transitioning to a women's multivitamin like Essentia once you finish taking TheraNatal Complete.
