21st Century Iron 65 mg

Brand: 21st Century · Form: TABLET [E0155]

Our assessment

The evidence shows that iron is a critical mineral for your health, but the 65 mg dose in this product is a high-potency supplement. For most adults, the RDA for iron is 8 mg to 18 mg daily, so this amount is intended for specific, diagnosed deficiencies. You should only take this dose under the guidance of a healthcare provider, as excess iron can be dangerous [NIH ODS].

How it works

Think of iron as a key component in your blood's oxygen transport system. It is essential for making hemoglobin, the protein in red blood cells that carries oxygen from your lungs to the rest of your body. Without enough iron, your body cannot produce enough healthy red blood cells, leading to fatigue and weakness [NIH ODS].

Safety profile

Data not available for this specific iron product. However, FDA has received a total of 592,059 adverse event reports across all supplement categories. High doses of iron can cause stomach pain, constipation, nausea, and vomiting. The most serious risk is iron toxicity, which can damage the liver and other organs, especially in children [FDA data].

Our recommendation

Do not take 65 mg of iron unless a blood test has confirmed iron deficiency and your doctor has recommended this dose. Start with a lower dose if possible, and always take iron with a small amount of vitamin C (like a glass of orange juice) to improve absorption. Store this product safely out of reach of children, as iron overdose is a leading cause of poisoning in kids [NIH ODS].
