Our assessment
The evidence shows that Natrol Probiotic Acidophilus BioBeads contains calcium, a mineral important for bone health. Our assessment is that this product may support bone density if you are not already meeting your calcium needs through diet. However, the data on calcium is mixed regarding heart and prostate cancer risk, and we must be clear about potential interactions [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It supports bone mineralization and helps with muscle relaxation and nerve signaling [NIH ODS]. For this product to be effective, you need to consider your total daily calcium intake from all sources.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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] [FDA data].
Our recommendation
Start by assessing your dietary calcium intake before adding this supplement. Be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend consulting your healthcare provider to check if this product is right for you, especially if you take any of these medications. Data not available for specific dosage or form of calcium in this product.
