Our assessment
The evidence shows that Premier Research Labs Premier Probiotic Caps contains calcium, a mineral essential for bone health. Based on the data provided, our assessment is that this product can support your bone density and nerve function, but you must be aware of the specific safety risks and medication interactions associated with calcium supplementation [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and density, and it is also critical for neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your muscles relax after contracting and ensures your nerves send signals properly.
Safety profile
The FDA received a total of 592,059 adverse event reports across all products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in your blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
We recommend you check your total daily calcium intake from all sources (food and supplements) to avoid exceeding safe levels. If you take bisphosphonates, tetracycline or fluoroquinolone antibiotics, levothyroxine, or phenytoin, take this supplement at least two hours apart from those medications, as calcium can reduce their absorption [NIH ODS]. Data not available on the specific probiotic strains or their colony-forming units (CFUs) in this product.
