Our assessment
The evidence shows that NOW Probiotic-10 25 Billion contains calcium as an ingredient. Our assessment is that while calcium is essential for health, this product is primarily a probiotic, and you should be aware of the potential risks and interactions associated with its calcium content. Data not available on the specific probiotic strains in this product.
How it works
Calcium supports bone mineralization and density, and it plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as a structural builder for your bones and a regulator for your muscles and nerves [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though a specific count for this product is not available. Regarding calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because data on the specific probiotic strains is not available, we cannot make a specific recommendation for this product for general gut health. If you are taking any of the medications listed, be aware that the calcium in this supplement could interfere with their absorption [NIH ODS]. For a more targeted recommendation, consider seeking a product with documented strain-specific research.
