Our assessment
Our assessment: This product contains calcium, a mineral essential for bone health and nerve function. The evidence shows that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, it is critical to understand that the data on calcium safety is nuanced and requires careful attention to dosage.
How it works
Think of calcium as a structural building block — it is a primary component of your bones and teeth, helping to maintain bone density and mineral deposition. It also acts as a messenger for your nerves and muscles, supporting muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports for all dietary supplements, but specific side effect counts for calcium alone are not broken out in the data provided. However, the data states 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 approach this supplement with caution. Do not exceed the recommended daily intake for your age and sex. If you take any medications listed in the interactions, take calcium at least two hours apart. Data on the specific dose of calcium in this product is not available, so consult your healthcare provider to determine if this supplement is appropriate for you and to discuss potential risks, especially if you have a history of kidney stones, heart disease, or prostate cancer [NIH ODS].
