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. For more information, speak with your physician about choosing a prenatal multivitamin that meets your specific nutrient needs.^‡◆

From Soil to Supplement: Understanding Environmental Elements

Trace heavy metals can occur in the environment on their own or from human activities and can be present in soil-grown ingredients, so small amounts may show up in foods and supplements. Our standard is set to keep levels in prenatal supplements much lower than what is found in common foods, such as strawberries, brown rice and spinach.

If you would like to learn more about heavy metals in the environment and in food, visit the FDA website for Environmental Contaminants in Food.

Commonly Asked Questions

MORE FAQS

Nature Made experts answer questions about prenatal supplements and product safety.

Pregnancy increases the need for many nutrients that support both mom's health and baby's development. Even with a healthy diet, research based on nationally representative NHANES data from the CDC shows that many pregnant women do not meet recommended intakes for key nutrients through their diet, including folate, choline, and vitamin D, as well as minerals such as iron, calcium, and magnesium.[1] These nutrients help support the baby's brain, nervous system, bone health and overall growth, while also supporting mom's health throughout pregnancy. Taking a prenatal supplement can help fill nutritional gaps and provide nutritional support during pregnancy.^†
Yes. Nature Made prenatal multivitamins are a safe and trusted way to help deliver essential nutrients for both mom and baby during pregnancy. Every batch is rigorously tested to ensure it meets California Proposition 65 safe harbor levels, which are among the strictest standards in the industry. Our quality checks start with ingredient sourcing and continue through manufacturing, so consumers can feel confident about the safety and quality of their prenatal supplements.
Many important prenatal nutrients, including minerals such as iron and calcium, come from sources in the earth. Because heavy metals occur in soil, water and the environment, trace amounts can be found in many foods, beverages and dietary supplements, including prenatal vitamins. Modern laboratory equipment can detect extremely small amounts of substances, often at parts-per-billion levels, which is roughly the equivalent of one drop of water in an Olympic-size swimming pool. What matters is not whether a substance can be detected, but whether it is present at a level that meets established safety standards. Nature Made uses rigorous testing and strict quality standards to ensure these trace levels remain well below established safety limits. Every lot is carefully tested so women can feel confident in the quality of their prenatal supplements.
Many vitamins and minerals are sourced from materials found in soil, water, and other parts of the environment. Because the composition of these source materials can vary slightly from one supplier, location, or production lot to another, small differences in test results are expected. These variations can occur even when the same product is manufactured using the same process and quality standards. Every lot is tested and must meet Nature Made's strict quality standards before release.
