Bio-K Plus 100% Probiotic

Brand: Bio-K Plus · Form: CAPSULE [E0159] On Market

Our assessment

The evidence shows that Bio-K Plus 100% Probiotic contains calcium, which is a mineral essential for bone health. Our assessment is that this product may support your bone density and muscle function, but the data provided is limited to the calcium content alone. We cannot evaluate the probiotic strains or overall effectiveness based on the available information [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton. It works by supporting bone mineralization and mineral deposition, which helps maintain strong bones. Additionally, calcium plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

Data on adverse events for this specific product is not available. However, for calcium supplements in general, safety concerns include potential risks with high intakes. Some research suggests that high calcium 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]. The FDA has received a total of 592,059 adverse event reports across all supplements, but this number is not specific to this product [FDA data].

Our recommendation

Our recommendation is to consider your overall calcium intake from all sources, including food and other supplements, before adding this product. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement separately from these medications. Because data on the probiotic strains is not available, we cannot provide a specific recommendation for probiotic benefits. Consult your healthcare provider to determine if this product is right for your needs.
