Brand: Swanson Premium Brand · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this Swanson Premium Brand Iron (Ferrous Fumarate) 18 mg supplement provides a standard dose of iron, a mineral essential for making hemoglobin and transporting oxygen. However, based on the data provided, the ingredient information for this specific product is incomplete, as the label is listed as "See label" and no mechanism or interaction data for iron is included. For calcium, the data shows it supports bone mineralization and nerve signaling, but high intakes may increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Iron is a critical component of hemoglobin, which carries oxygen in your blood. Without it, you can feel tired and weak. The calcium data provided explains that this mineral works as a master regulator for bone density and muscle relaxation, helping your nervous system and skeletal structure function properly [NIH ODS].
Safety profile
Data not available for iron-specific side effects from the FDA data provided. However, the FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high levels can cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Because the data for this specific iron product is limited, we recommend you speak with your healthcare provider before starting this supplement. If you are looking to support bone health, do not exceed the recommended intake of calcium without medical guidance, as high levels carry specific risks [NIH ODS]. Always check the label for complete ingredient and dosing information.
