Our assessment
Our assessment: The evidence shows that calcium is essential for bone health, but you should be cautious with high-dose supplementation. For a product like Signature Care High Potency Iron 65 mg, the primary ingredient is iron, but we must address the calcium data provided. The data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key structural component — it supports bone density and mineral deposition, and it helps your muscles relax and nerves signal properly [NIH ODS]. When you take calcium, it works with other minerals to maintain skeletal strength and neuromuscular function.
Safety profile
Based on FDA data, there are 592,059 total adverse event reports across all supplements, but specific side effect counts for calcium alone are not broken out in this data. Side effects from high calcium levels include 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
Our recommendation: Since this product is Signature Care High Potency Iron 65 mg, you should not take additional calcium without consulting a pharmacist or doctor, as calcium can interfere with iron absorption. The data does not provide specific dosing for calcium in this product. Stick to the recommended dietary allowance for calcium from food sources unless your healthcare provider advises otherwise [NIH ODS].
