River's Edge Multi-Nate 30 DHA 275/400 mg Multi-Nate 30 Prenatal Multivitamin & Mineral

Our assessment

The evidence shows that River's Edge Multi-Nate 30 DHA 275/400 mg is a prenatal multivitamin containing calcium, which plays a key role in your and your baby's health. However, we must be specific about what the data supports and what it doesn't. The calcium in this product supports bone density and mineral deposition, as well as muscle relaxation and nerve signaling [NIH ODS]. You should not rely on this supplement alone for all your prenatal nutritional needs, as data on the other ingredients in this specific product is not available.

How it works

Think of calcium as a structural builder and a signal messenger. It directly supports bone mineralization, helping to deposit the dense minerals your baby's developing skeleton requires [NIH ODS]. It also aids in neuromuscular relaxation, meaning it helps your muscles and nerves communicate properly, which is especially important during pregnancy [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our assessment is that you should use this prenatal supplement as directed by your healthcare provider, but be mindful of your total calcium intake from all sources. Do not exceed the recommended dose, as high calcium levels carry serious risks [NIH ODS]. If you take any of the listed medications (like thyroid hormone or certain antibiotics), separate your supplement intake by at least two hours to avoid absorption issues [NIH ODS]. Always discuss any new supplement regimen with your doctor.
