Our assessment

Data not available for the specific brand's reputation or quality testing beyond general FDA oversight.
How it works
Think of calcium as the building block for your bones. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your muscles relax after contracting and supports proper communication between your nerves and muscles.
Safety profile
FDA received 592,059 adverse event reports for calcium-containing supplements. Side effects reported include constipation, nausea, and weight loss at high intakes. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [FDA data]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start by checking your total daily calcium intake from food and other supplements. The 600 mg from this product is a common dose, but do not exceed 2,000-2,500 mg total per day from all sources. Take this supplement with food for better absorption. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Space your dose at least 2 hours apart from these medications.
