Our assessment

The evidence shows that calcium is essential for your bone health and muscle function. For the Bronson Laboratories Calcium 1000 Complex, our assessment is that it can be a useful tool to help you meet your daily calcium needs, but you must pay close attention to the total amount of calcium you get from all sources, including food and other supplements [NIH ODS].

How it works

Think of calcium as a key building block for your body. It supports bone mineralization and density, which helps keep your skeleton strong. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

Data not available on specific side effects for this product from the FDA data provided. However, general safety information shows that high calcium intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in your 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]. The FDA has received a total of 592,059 adverse event reports across all products, but the specific number for this supplement is not available [FDA data].

Our recommendation

We recommend you carefully review your total daily calcium intake from food and all supplements to avoid exceeding the upper limit. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take this supplement at a different time than these medications. Always consult your healthcare provider before starting a new supplement.
