Copper Gluconate Supplement: Zinc Balance and the 0.052 mg Line
A copper gluconate supplement supplies copper in tiny amounts, because the body needs less than a milligram a day. Reviralis prints copper gluconate 0.052 mg per two capsules, 6% of the Daily Value. The adult need is 0.9 mg and the upper limit 10 mg. Zinc is the nutrient that can crowd copper out.

Why is a copper gluconate supplement so small?
Because adults need only 0.9 mg of copper a day, and the upper limit is 10 mg (NIH ODS, Copper).
The label line 0.052 mg is the same as 52 mcg. That is 5.8% of the need and 0.5% of the limit. Copper is a trace mineral: it helps make red blood cells and connective tissue, and it is found in shellfish, nuts, seeds and whole grains.
| Measure | Amount | Share the label line fills |
|---|---|---|
| Label line (2 capsules) | 0.052 mg (52 mcg), 6% DV | Printed |
| Adult need | 0.9 mg (900 mcg) | 5.8% |
| Upper limit | 10 mg | 0.5% |
How do copper and zinc balance each other?
They compete, so excess zinc lowers copper over time (NIH ODS, Zinc).
The same label prints zinc 10 mg, about 192 times the copper weight. NIH ties copper loss to zinc above 40 mg for weeks, so 10 mg is not the worry. Some makers add a little copper to zinc products as a precaution. Whether that is the reason here, the label does not say. For the zinc side, see the zinc post.
Who should ask before taking a copper product?
People with a condition that changes how the body handles copper, such as Wilson disease, and people with liver disease.
Ask your clinician if that is you, whatever the dose. Also ask if you are pregnant or nursing, as the Reviralis label advises. Keep taking prescribed medicine, including any antiviral, and bring the bottle to the pharmacy counter. No source tests Reviralis itself.

See packsWhat do the other trace mineral lines look like?
All small: chromium 12 mcg, manganese 0.4 mg, molybdenum 10 mcg and selenium 50 mcg.
Only zinc and selenium come close to a full day's need. The copper line is the smallest by weight. A tiny line is not a flaw. It reflects how little the body needs, and why a pile of trace minerals on a label should not impress anyone by itself.
FAQ01
Reviralis questions people ask
How much copper is in Reviralis?
The label prints copper as copper gluconate, 0.052 mg per two capsules, or 6% of the Daily Value. That equals 52 mcg. Adults need 0.9 mg and the upper limit is 10 mg.
Why do zinc products add copper?
Zinc and copper compete for absorption, and excess zinc over weeks can lower copper. Some makers add a little copper for that reason. The Reviralis label does not give its reason.
Is 0.052 mg of copper enough?
It is about 6% of the 0.9 mg adult need, so it is a small top-up, not a full source. Shellfish, nuts, seeds and whole grains supply most copper in the diet.
What is the upper limit for copper?
NIH sets the adult upper limit at 10 mg a day. The label line of 0.052 mg is about half of one percent of that. People with Wilson disease should ask a clinician before any copper product.
