Pure Encapsulations Iron-C
Brand: Pure Encapsulations · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Pure Encapsulations Iron-C provides calcium, a mineral essential for bone health and muscle function. However, data on this specific product is limited, and we must rely on general calcium supplementation research to guide you. Our assessment is that calcium from food sources is generally preferred, but supplements can fill a gap when dietary intake is insufficient.
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. If your diet is low in dairy, leafy greens, or fortified foods, a supplement like this can help you meet your daily needs.
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplement categories, though data specific to this product is not available. For calcium, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake. Most adults need 1,000 to 1,200 mg daily from all sources [NIH ODS]. Do not exceed the tolerable upper intake level without medical supervision. If you take thyroid medication or antibiotics, separate your dose from calcium by at least 2 hours [NIH ODS]. Our recommendation: prioritize food sources first, and use this supplement only to bridge a verified gap. Consult your doctor before starting, especially if you have kidney issues or a history of heart disease.
