Sundown Naturals Iron 65 mg
Brand: Sundown Naturals · Form: TABLET [E0155]
Our assessment
The evidence shows that Sundown Naturals Iron 65 mg provides a high dose of elemental iron. However, we must be clear: the data available for this specific product is limited, as the label and ingredient information are marked "See label," and the NIH ODS data provided is for Calcium, not Iron. Based on the data we have, we cannot make a direct assessment of this iron supplement’s efficacy or mechanism. For general context, calcium supports bone mineralization and neuromuscular relaxation [NIH ODS], but this does not apply to your product.
How it works
Because the data provided focuses on calcium, we cannot describe how this iron supplement works. For calcium, think of it as a building block for your bones and a regulator for muscle and nerve function [NIH ODS]. However, for iron specifically, data is not available to explain its mechanism in this context.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For this specific product, side effect data is not available. Based on the calcium data, 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
We cannot recommend Sundown Naturals Iron 65 mg based on the data provided, as the ingredient-specific information is missing. For calcium, you should be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Before taking this iron supplement, consult your healthcare provider to determine if it is appropriate for you, as we do not have sufficient data to confirm its safety or efficacy.
