Our assessment

Our assessment is based on the calcium content and general safety data from the NIH [NIH ODS].
How it works
Think of calcium as a building block and a messenger. It supports bone mineralization, helping deposit minerals into your skeleton for density and strength. It also plays a key role in neuromuscular relaxation, which means it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should discuss calcium supplementation with your healthcare provider, especially if you take any medications. Stick to recommended daily intake levels and do not exceed them without medical supervision, as the risks from high calcium intake are serious [NIH ODS]. Data not available for specific side effect report counts for this product.
