Our assessment
Our assessment: The evidence shows that the primary ingredient in this product, calcium, is critical for bone health, but the data also reveals significant safety considerations you need to be aware of. While calcium supports bone density and muscle relaxation [NIH ODS], we must be cautious about the high level of adverse event reports associated with this supplement category.
How it works
Think of calcium as a structural building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition, while also aiding neuromuscular relaxation to support muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The FDA received 592,059 adverse event reports for products in this category [FDA data]. The data shows that high calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: You should only take calcium supplements if you have a confirmed deficiency or cannot meet your needs through diet. Be aware of the potential risks, including interactions with prescription medications. Data not available on the specific dosage for this product, so follow the label instructions carefully and consult your healthcare provider before starting this supplement [NIH ODS] [FDA data].
