Mommy's Bliss Probiotic Drops + Vitamin D

Our assessment

The evidence shows that this product combines two ingredients—calcium and vitamin D—that work together to support bone health. However, based on the data provided, our assessment is that you should be aware of the specific risks associated with high calcium intake, especially if you are taking other medications. The FDA has received a total of 592,059 adverse event reports for products in this category, which signals a need for careful monitoring [FDA data].

How it works

Think of calcium as a building block for your bones. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS]. Vitamin D helps your body absorb this calcium, making the combination effective for maintaining strong bones.

Safety profile

Data not available for side-effect counts specific to this product. However, based on the calcium data, 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation is to use this product only if you have a confirmed need for supplemental calcium and vitamin D. Be cautious with your total daily intake from all sources, as high levels pose serious risks. If you take any of the medications listed—such as thyroid medication or certain antibiotics—take this supplement at a different time of day to avoid absorption issues [NIH ODS]. Always consult your healthcare provider before starting, especially given the 592,059 total adverse event reports on file [FDA data].
