Rugby Prenatal Vitamins

Our assessment

The evidence shows that Rugby Prenatal Vitamins, like all prenatal supplements, are designed to fill nutritional gaps during pregnancy. The key ingredient with the most robust data from your provided information is calcium [NIH ODS]. While calcium is essential for your baby's bone development and your own nerve and muscle function, it is critical to understand the specific risks and interactions associated with this mineral [NIH ODS].

How it works

Think of calcium as a building block and a messenger. It supports bone mineralization, which is the process of depositing minerals into your skeleton to build strong, dense bones for both you and your developing baby [NIH ODS]. It also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS]. Getting enough calcium during pregnancy is vital, but more is not always better.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, though specific reports for Rugby Prenatal Vitamins are not isolated in this data. For the ingredient calcium, the data warns of significant risks from high intakes. High calcium levels in your 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].

Our recommendation

Our recommendation is to take this supplement exactly as directed by your healthcare provider. Do not take additional calcium supplements without medical advice, as the total calcium from your prenatal, other supplements, and diet can add up quickly [NIH ODS]. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these, separate your prenatal vitamin by at least 2 hours. Data on other ingredients in this specific product is not available.
