Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, the data on calcium supplementation is nuanced, and we recommend a cautious approach. For most adults, getting calcium from food is preferable, and supplements should only be used to fill a verified dietary gap [NIH ODS].
How it works
Think of calcium as the primary building block for your bones. It supports bone mineralization and density by helping deposit minerals into your skeleton. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for products in this category. Based on NIH data, high calcium intakes might increase the risk of heart disease and prostate cancer. Too much 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] [FDA data].
Our recommendation
Before taking this supplement, you should calculate your daily calcium intake from food. Do not exceed 2,000–2,500 mg of total calcium per day from all sources. If you take medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, you should take this supplement at a different time to avoid absorption issues [NIH ODS]. We recommend discussing your specific needs with your healthcare provider.
