Our assessment
The evidence shows that the calcium in this supplement is important for bone health, but you should be cautious about your total daily intake from all sources. Our assessment is that for most adults, getting calcium from food is safer than relying on supplements, especially since high intakes from supplements may carry risks [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone density and mineral deposition, which keeps your bones strong. It also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Data not available for side effects specific to this product. The FDA received a total of 592,059 adverse event reports across all dietary supplements, but report counts for individual ingredients like calcium are not provided here. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels 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
You should check your total daily calcium intake from food and other supplements to avoid exceeding recommended levels. Be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend discussing this supplement with your doctor, especially if you take any of these medications or have a history of kidney issues.
