Sunshine Naturals Iron
Brand: Sunshine Naturals · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sunshine Naturals Iron is a straightforward mineral supplement. However, based on the data provided, the product label lists "Calcium" as the ingredient, not iron. Our assessment: this product appears to be a calcium supplement. For a general audience, calcium is essential for bone health, but you need to be aware of its specific benefits and risks [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling. Without adequate calcium, your body will pull it from your bones, which can weaken them over time [NIH ODS].
Safety profile
Safety data is critical here. The FDA received a total of 592,059 adverse event reports for supplements in this category. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Symptoms of too much calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of medications like bisphosphonates, certain antibiotics (tetracycline and fluoroquinolone), levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the recommended dosage of this specific product. We recommend you check the label for a specific serving size. For general calcium guidance, do not exceed the tolerable upper intake level without medical supervision, and always take calcium supplements at a different time than your thyroid medication or antibiotics to avoid absorption problems [NIH ODS].
