Exchange Select Zinc 50 mg
Brand: Exchange Select · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 50 mg of zinc per serving, which far exceeds the recommended daily allowance for adults [NIH ODS]. While zinc is an essential mineral, taking 50 mg daily can lead to copper deficiency over time, and we generally do not recommend this dose without a confirmed deficiency and medical supervision [NIH ODS].
How it works
Zinc supports your immune system and helps with wound healing. However, at 50 mg, you are taking more than three times the RDA for most adults [NIH ODS]. Think of it like a high-dose therapy — it is not intended for daily, long-term use unless prescribed by a doctor for a specific condition [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements [FDA data]. For zinc specifically, high doses can cause nausea, vomiting, and reduced copper absorption [NIH ODS]. Data not available for side effect report counts specific to this product. Taking 50 mg daily for extended periods may weaken your immune system rather than help it [NIH ODS].
Our recommendation
We recommend you do not take this product daily. A safer dose for general health is 8-11 mg per day for adults [NIH ODS]. If you choose to use this product, take it only for a short period (such as when fighting a cold) and consider taking a copper supplement to prevent deficiency [NIH ODS]. Always consult a healthcare provider before starting high-dose zinc [NIH ODS].
