Our assessment
Our assessment: This product provides a combination of calcium and vitamin D-3. The evidence shows that calcium is essential for bone mineralization and neuromuscular function [NIH ODS]. However, you need to be aware of significant safety considerations and potential medication interactions before starting this supplement.
How it works
Calcium acts as a master regulator for your body, supporting bone density and mineral deposition, while also aiding muscle relaxation and nerve signaling [NIH ODS]. This combination helps maintain skeletal health and proper neuromuscular function.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Data on the exact number of adverse event reports for this specific product is not available.
Our recommendation
We recommend consulting your healthcare provider before using this supplement, especially if you take any medications. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should also be cautious not to exceed recommended daily intakes, as high levels pose serious health risks. Start with the lowest effective dose under medical supervision [NIH ODS].
