Allergy Research Group Zinc Citrate 50
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains 50 mg of zinc citrate per serving. Zinc is an essential mineral that supports immune function and wound healing. However, our assessment is that you should be cautious with this dosage, as the Tolerable Upper Intake Level (UL) for zinc is 40 mg daily for adults. Taking 50 mg may exceed safe limits without medical supervision [NIH ODS].
How it works
Think of zinc as a gatekeeper for your immune system — it helps your body produce and activate T-cells, which are critical for fighting off infections. Zinc also supports over 300 enzymatic reactions in your body, including those involved in DNA synthesis and protein production [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For zinc specifically, side effects from high doses include nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. Chronic intake above 40 mg daily can lead to copper deficiency, which may cause anemia and neurological issues. Data on exact report counts for zinc citrate is not available [FDA data] [NIH ODS].
Our recommendation
We recommend you do not take this supplement without first consulting a healthcare provider. The 50 mg dose exceeds the safe upper limit of 40 mg per day. If you have a confirmed zinc deficiency, your doctor can advise on appropriate dosing. For general immune support, a lower dose of 15-25 mg daily is typically sufficient [NIH ODS].
