Our assessment
The evidence shows that Nature's Way Completia Prenatal Multi-Vitamin contains calcium, which is a key mineral for supporting your health during pregnancy. However, the data we have is limited to this single ingredient, so a full assessment of the complete formula is not possible based on the information provided. Our assessment focuses on what the data confirms: calcium plays a critical role in your body, but you need to be aware of specific safety considerations [NIH ODS].
How it works
Think of calcium as a structural builder and signal messenger for your body. It supports bone mineralization, helping to deposit minerals into your skeleton to maintain bone density. At the same time, calcium supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves transmit signals properly. This dual role is essential during pregnancy for both your health and your baby's developing bones [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for all supplements, but specific report counts for this product are not available. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you take this prenatal vitamin as directed on the label, but be mindful of your total calcium intake from all sources, including food and other supplements. Because calcium can interfere with certain medications, take this supplement at a different time than any prescription drugs you may be using. If you have a history of kidney stones, heart conditions, or take thyroid medication or antibiotics, consult your healthcare provider before use. Data not available on other ingredients in this formula [NIH ODS].
