CVS Pharmacy Extra Strength Probiotic 15 mg

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, the data for this specific CVS Pharmacy product is limited. For calcium specifically, the primary role is supporting bone density and neuromuscular relaxation [NIH ODS]. You should be aware that calcium supplements carry important safety considerations, and you need to manage your intake carefully.

How it works

Think of calcium as a structural building block for your bones. It supports bone mineralization, which is the process of depositing minerals into your bone matrix to keep them strong [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, 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

Before taking this product, you should consult your healthcare provider to determine if you need extra calcium. If you take any medications, especially those listed above, discuss potential interactions with your pharmacist or doctor [NIH ODS]. Start with the lowest effective dose and monitor for side effects like constipation or nausea. Data not available for the specific probiotic ingredients in this product.
