  • How much vitamin D do I need while I'm breastfeeding?
    The Canadian Paediatric Society recommends that breastfed infants get 400 IU (international units) of vitamin D per day. Babies that live in northern communities or that have additional risk factors should get 800 IU per day. Without supplementation, the amount of vitamin D in breast milk is too low to support healthy vitamin D levels in most breastfed infants. However, studies have shown that only 20% of families consistently give their baby vitamin D drops.

    Fortunately, a study found that breastfeeding mothers who took 160 mcg (6,400 IU) of supplemental vitamin D3 each day provided enough vitamin D to their babies through their breast milk alone. TheraNatal Lactation Complete provides 160 mcg (6,400 IU) of vitamin D3 per day, eliminating the need for infant vitamin D drops.

    Do not give your baby vitamin D drops while taking TheraNatal Lactation Complete.

    Can I start taking TheraNatal Lactation Complete while I am pregnant?
    No, it is not recommended. TheraNatal Lactation Complete is specifically formulated to support your nutrient needs while breastfeeding and may not be appropriate to meet your nutrient needs during pregnancy.
    What is the source of DHA in TheraNatal Lactation Complete?
    TheraNatal Complete contains 300 mg of DHA from AlaskOmega®, a highly purified omega-3 fish oil concentrate that’s sustainably sourced from wild-caught Alaska pollock from the Bering Sea and Gulf of Alaska.

    Every batch of fish oil in TheraNatal Complete is also tested and certified by the International Fish Oil Standards (IFOS) program to ensure it’s free from harmful contaminants, including mercury, lead, and PCBs. It has continually received the highest rating of five stars from IFOS, which reflects its exceptional quality, purity, and safety.

    Can I take TheraNatal Lactation Complete if I'm allergic to shellfish?
    TheraNatal Lactation Complete does not contain shellfish. 

    If you have reacted to radiocontrast material or antiseptics that contain iodine, you may still be able to safely take TheraNatal Complete, even though it contains iodine. These reactions are commonly confused with a sensitivity to iodine or shellfish, though studies have shown that they are not related.

    Can I take TheraNatal Lactation Complete if I'm allergic to fish?
    TheraNatal Lactation Complete contains omega-3 fish oil derived from wild-caught Alaska pollock. If you are allergic to fish, the fish oil softgel in TheraNatal Lactation Complete may not be safe for you. Consult your allergist and/or healthcare team.
