Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, you should be aware of important safety considerations. Our assessment is that while calcium supports bone density and nerve signaling, the data on high intakes raises significant concerns [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signal regulator for your muscles and nerves. It supports bone mineralization and helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, though specific data for this product is not available. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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] [FDA data].
Our recommendation
If you choose to use this supplement, be cautious about your total calcium intake from all sources. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend consulting your healthcare provider to assess your individual needs and potential interactions. Data on the specific probiotic and fiber content is not available.
