Our assessment
The evidence shows that this product combines a probiotic with vitamin D, but the data provided does not include specific information on vitamin D itself. For the calcium content that may be relevant, our assessment is that calcium is a well-supported mineral for bone health, but you should be aware of significant safety considerations. The data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your muscles — it helps deposit minerals into your bone matrix and supports proper muscle contraction and nerve signaling [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all products in this database [FDA data]. For calcium specifically, the data notes that high intakes might increase the risk of heart disease and prostate cancer. High calcium levels in 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on side effects specific to this product is not available.
Our recommendation
Given the data provided, do not rely on this product as your primary calcium source without consulting your healthcare provider. Be aware of the potential for high calcium intakes to cause serious side effects and medication interactions [NIH ODS]. If you are taking any of the listed medications, discuss timing with your pharmacist to avoid absorption issues. Data not available for other ingredients in this specific product.
