Trace Minerals Research Ionic Copper 3 mg
Brand: Trace Minerals Research · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
Our assessment: Trace Minerals Research Ionic Copper 3 mg provides a specific form of copper. For most adults, the Recommended Dietary Allowance (RDA) for copper is 900 mcg (0.9 mg) per day, and the Tolerable Upper Intake Level (UL) is 10,000 mcg (10 mg) per day [NIH ODS]. A 3 mg dose is above the RDA but well below the UL, so it is a reasonable amount for supplementation if you have a confirmed need. However, data on the specific benefits of this ionic form versus other copper supplements is not available. We cannot make a specific claim about this product's efficacy beyond the general role of copper in the body.
How it works
Copper is an essential trace mineral that acts as a cofactor for several critical enzymes. It is necessary for energy production, iron metabolism, and the formation of connective tissue and neurotransmitters [NIH ODS]. It also helps maintain nerve cells and your immune system [NIH ODS]. The "ionic" form in this product means the copper is in a dissolved, charged state, which is the form your body can absorb. Data on the specific absorption rate of this particular product compared to other copper forms is not available.
Safety profile
The safety profile for copper is well-established. The FDA has received adverse event reports for copper products. Side effects from excessive copper intake can include nausea, vomiting, and abdominal pain [FDA data]. Data on specific report counts for this exact product is not available. Taking 3 mg daily is generally considered safe for most adults, but taking too much copper over time, especially amounts above the UL of 10 mg, can lead to liver damage and other serious issues [NIH ODS]. Copper can also interact with zinc, as high doses of one can cause a deficiency in the other [NIH ODS].
Our recommendation
Our recommendation: Do not take this supplement unless you have a confirmed copper deficiency or your healthcare provider has advised it. The vast majority of people get enough copper from their diet, which includes foods like liver, shellfish, nuts, and seeds [NIH ODS]. If you are taking a zinc supplement, be aware that high zinc intake can interfere with copper absorption, and you may need a separate copper supplement to maintain balance [NIH ODS]. Start with the lowest effective dose and monitor for any side effects. Always consult your doctor before starting a new supplement, especially one containing a trace mineral.
