Our assessment
The evidence shows that this product is primarily a source of calcium, a mineral essential for bone health. Our assessment: if you are looking to support bone density and muscle function, calcium is a well-supported choice. However, you should be aware of the potential risks and medication interactions associated with high calcium intake [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for specific side effects of this product. The FDA has received a total of 592,059 adverse event reports across all dietary supplements [FDA data]. For calcium generally, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium can cause poor muscle tone, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you consider your total daily calcium intake from food and supplements. If you take this product, take it separately from any medications listed above by at least 2 hours. Consult with your doctor before starting, especially if you have a history of kidney stones, heart disease, or take prescription medications [NIH ODS].
