Our assessment
The evidence shows that Sundown Naturals Perfect Iron is a calcium supplement.

How it works
Calcium acts as a master regulator for your body. It is critical for bone mineralization, helping to deposit minerals and maintain bone density [NIH ODS]. It also supports neuromuscular relaxation and proper nerve signaling [NIH ODS]. Think of it as the key mineral that keeps your skeleton strong and your muscles and nerves communicating effectively.
Safety profile
Safety data is complex. The FDA has received 592,059 total adverse event reports for all supplements, but this number is not specific to calcium or this product [FDA data]. The NIH ODS warns that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high blood levels can cause serious issues including constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific dosage of this product. Do not exceed the daily recommended intake without medical supervision. If you take any of the listed medications, separate your calcium dose by at least 2 hours or as directed by your doctor. Before starting any supplement, especially one with potential serious side effects at high doses, consult with your healthcare provider [NIH ODS].
