Yes. While TheraNatal Complete is formulated to meet your needs during pregnancy, the nutrient doses in this prenatal are safe to take while you’re trying to conceive, too.

You can finish taking any remaining TheraNatal Complete after pregnancy.

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.

These reactions are commonly confused with a sensitivity to iodine or shellfish, though studies have shown that they are not related.
