Our Mandate

  • To provide authoritative information and guidance to pregnant or lactating patients and their health care providers regarding the fetal risks associated with natural health product (NHP) exposure and complementary and alternative medicine (CAM) treatments during pregnancy.
  • To research unanswered questions on the safety of NHPs during pregnancy and lactation, and maintain a vital training and educational program in the area of reproductive and developmental toxicology.
  • Learn more about research on nutrition

Complementary and Alternative Medicines and Therapies

Natural doesn't always mean safe.

But that doesn’t stop millions of people in North America, including pregnant women, from consuming natural health products. Natural health products (NHPs) include vitamins, minerals, amino acids, medicinal plants, fatty acids, probiotics, digestive enzymes, traditional Chinese medicines, nutritional supplements and homeopathic remedies.

Based on the risk of harm to the fetus associated with certain drugs, women and their health care providers may be hesitant to take or prescribe drugs during pregnancy. In cases where women choose to discontinue their drug use during pregnancy, they often seek NHPs as alternatives to pharmaceutical drugs. Are they safe during pregnancy? In some cases, we have evidence of safety for some vitamins, minerals and botanicals; in other cases, we simply do not know or have evidence of harm.

The aim of the MotherNature Network is ongoing research in this field. Here is a list of studies that have been undertaken as part of this initiative.

It's no longer as simple as "eating for two."

In fact, what we thought we knew about nutrition and weight gain during pregnancy doesn't always stand up against new clinical findings. Insufficient vitamin supplementation may spell trouble for the baby. Uncontrolled weight gain may predict long-term health problems for the mother. Women who gain excessive weight during pregnancy may also be setting the stage for obesity in their children.

Here's some research on Nutrition to consider and discuss with your doctor. This research was conducted by members of the MotherNature-Network.
