Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. However, our assessment is that you should approach this supplement with caution. The data on calcium is clear about both benefits and significant risks, and you need to be aware of both before taking it. For most adults, getting calcium from food is safer than from supplements [NIH ODS].

How it works

Think of calcium as a structural builder for your bones and a signal conductor for your nerves and muscles. It supports bone mineralization, meaning it helps deposit minerals into your skeleton to keep it dense and strong. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

The FDA has received 592,059 total adverse event reports for this product. Specific safety concerns from the data include: high calcium intake might increase the risk of heart disease and prostate cancer. Elevated 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] [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation is to prioritize dietary calcium sources like dairy, leafy greens, or fortified foods before considering this supplement. If you do choose to take it, do not exceed the recommended dose on the label. Be especially cautious if you have a history of kidney stones, heart disease, or if you take any of the medications listed in the safety profile. Talk to your doctor or a pharmacist to check for potential interactions with your current medications [NIH ODS].
