Our assessment
The evidence shows that this product contains calcium, a mineral with well-documented benefits for bone health. For a general audience seeking a probiotic, the presence of calcium is a relevant factor to consider. We will focus on the calcium component as provided in the data.
How it works
Calcium is a master regulator for your body. It supports bone mineralization and density, and it also plays a critical role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key building block for strong bones and the signal that helps your muscles relax after contracting.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high levels in the blood 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific probiotic strains or their dosage in this product. Because the data only provides information on calcium, we cannot recommend this product as a probiotic. If you are taking any of the medications listed, be aware that calcium may interfere with their absorption [NIH ODS]. Consult your personal healthcare provider for advice tailored to your health needs.
