Our assessment
The evidence shows that this product, Spring Valley Iron 65 mg, contains calcium as its active ingredient. Our assessment is that calcium is a well-established mineral for bone health, but the specific dosage and formulation of this product require careful consideration. The data provided does not include the exact amount of calcium per serving, so you should check the label to confirm the dosage [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but the specific report count for this product is not available. Regarding calcium, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Check the product label for the exact calcium dosage per serving. If you are taking any medications, particularly antibiotics or thyroid medication, take calcium supplements at least two hours apart. Do not exceed the recommended daily allowance without consulting your healthcare provider, as high calcium intakes carry significant risks [NIH ODS].
