Naturally—from soil, water, and the processing chain. They show up in trace amounts in many supplements (and in many of the foods you eat every day). What matters is the level, which is why we test every lot against the strictest US limits.
The FDA monitors heavy metal levels in some supplement categories but doesn't set universal limits across the entire industry. We hold ourselves to California Proposition 65 (widely considered the strictest US standard!) and test every batch against it.
Short answer: trace levels can show up in almost any prenatal that includes minerals—not because something's wrong, but because heavy metals are naturally present in the soil, water, and food chain those minerals come from.
Prenatal multivitamins containing certain minerals critical to support an expectant person's health and proper development of their fetus may contain trace levels of heavy metals that occur in the environment naturally or from human activities.
The levels of heavy metals in prenatal multivitamin ingredients may vary depending on whether and at what levels the prenatal multivitamin contains these ingredients, as well as the location from which the ingredients are sourced.
Certain foods containing minerals critical to support an expectant person's health and proper development of their fetus may also contain heavy metals. For more information, speak with your physician about choosing a prenatal multivitamin that meets your specific nutrient needs.
