21st Century Prenatal Multivitamin/Mineral + DHA Multivitamin/Mineral
Brand: 21st Century · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that prenatal multivitamins are a practical way to fill nutrient gaps during pregnancy. However, the specific product you asked about—21st Century Prenatal Multivitamin/Mineral + DHA—has minimal public data available. We can only speak to the ingredients based on the data provided. For calcium, one of its key ingredients, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a foundation builder for your baby’s developing skeleton. It also plays a role in muscle relaxation and nerve signaling, which is especially important as your body adapts to pregnancy [NIH ODS]. The DHA component is included for fetal brain and eye development, though specific data for this product’s formulation is not available.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, but specific adverse event counts for this 21st Century prenatal product are not available. For calcium specifically, the data warns that high intakes may increase the risk of heart disease and prostate cancer, and can cause side effects such as constipation, nausea, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications like thyroid hormone and certain antibiotics [NIH ODS].
Our recommendation
Start by checking the label to confirm it meets your specific nutritional needs, as the label data here is marked "See label." If you are taking any medications, especially for thyroid issues or infections, discuss timing with your doctor to avoid calcium interactions [NIH ODS]. Because specific safety data for this exact product is limited, we recommend sticking with well-studied prenatal brands that have published clinical evidence.
