Our assessment
Our assessment: The evidence on calcium is clear — it is essential for bone health, but supplementation requires caution. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. You should carefully evaluate your dietary calcium intake before adding a supplement.
How it works
Think of calcium as a structural cornerstone for your body. It supports bone density and mineral deposition, and it also helps with muscle relaxation and nerve signaling [NIH ODS]. This makes it vital for your skeletal strength and neuromuscular function.
Safety profile
The FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Before taking this supplement, have your healthcare provider assess your total calcium intake from food and other supplements. Do not exceed the RDA without medical supervision. If you take any of the listed medications, separate them from calcium by at least two hours [NIH ODS]. For the specific dosage of this Premier Research Labs product, data is not available for the liquid formulation.
