Swanson Premium Brand Zinc Picolinate 22 mg
Brand: Swanson Premium Brand · Form: CAPSULE [E0159]
Our assessment
Our assessment: Zinc is an essential mineral that plays a critical role in immune function, but the evidence shows that 22 mg of zinc picolinate is a high dose. The Tolerable Upper Intake Level (UL) for zinc from all sources is 40 mg daily for adults [NIH ODS]. Since you are likely getting zinc from food, this supplement could push your total intake close to the UL. We recommend caution with this product.
How it works
Zinc picolinate is a form of zinc bound to picolinic acid, which is thought to improve absorption. Think of zinc as a gatekeeper for your immune system — it helps your body produce and activate T-cells, which are essential for fighting off infections. Zinc also supports wound healing and DNA synthesis [NIH ODS].
Safety profile
Data not available for adverse events specific to this product. However, the FDA has received 592,059 total adverse event reports across all supplement categories [FDA data]. For zinc specifically, taking high doses over time can lead to copper deficiency, nausea, and a metallic taste in the mouth. Taking this 22 mg dose on an empty stomach may cause stomach upset [NIH ODS].
Our recommendation
We recommend you start with a lower dose, such as 11 mg daily, especially if you eat zinc-rich foods like meat, shellfish, or beans. Do not take this supplement with calcium, iron, or certain antibiotics, as they can interfere with absorption [NIH ODS]. For immune support, a standard 11 mg dose is sufficient for most adults.
