Trace Minerals Research Ionic Iron 22 mg

Our assessment

The evidence shows that Trace Minerals Research Ionic Iron 22 mg provides a specific dose of iron in a liquid ionic form. For iron supplementation, it is critical to use only the precise amount you need, as both deficiency and excess carry significant health risks. Our assessment is that this product may be appropriate for individuals with a confirmed iron deficiency, but it is not a supplement to take without a doctor’s guidance and lab testing. Data on the specific efficacy of this ionic form compared to other iron supplements is not available.

How it works

Iron is a critical mineral that your body uses to make hemoglobin, the protein in red blood cells that carries oxygen from your lungs to all your tissues [NIH ODS]. Without enough iron, your body cannot produce enough healthy oxygen-carrying red blood cells, leading to fatigue and weakness. An "ionic" form means the iron is in a liquid solution of charged particles, which some manufacturers claim allows for faster absorption, though this specific claim is not verified by the data provided. The recommended dietary allowance (RDA) for iron is 8 mg daily for adult men and 18 mg daily for premenopausal women [NIH ODS].

Safety profile

Safety data specific to this product is not available. However, iron is a potent mineral with a narrow safety margin. The FDA has received adverse event reports for iron supplements, including 48 reports of nausea, 22 reports of constipation, and 15 reports of abdominal pain [FDA data]. Taking too much iron can be toxic, especially for children, and can cause gastrointestinal distress and damage to the lining of the stomach. Anyone with hemochromatosis, a genetic condition causing iron overload, should avoid all iron supplements [NIH ODS].

Our recommendation

We recommend you only take this product if a healthcare provider has confirmed you have iron deficiency through a blood test (such as a ferritin or hemoglobin test). Do not exceed the recommended dose of 22 mg per day, as this amount exceeds the RDA for adult men. Start by taking it with a small amount of food to reduce stomach upset, but avoid taking it with calcium-rich foods or coffee, which can block absorption [NIH ODS]. If you experience constipation or nausea, reduce the dose or take it every other day. Always keep iron supplements out of reach of children.

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
