Nutricost Zinc Picolinate 50 mg
Brand: Nutricost · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Nutricost Zinc Picolinate 50 mg provides a highly absorbable form of zinc. However, the 50 mg dose is significantly above the Tolerable Upper Intake Level (UL) of 40 mg per day for adults, which raises a safety concern [NIH ODS]. Our assessment is that you should be cautious with this product, as long-term use at this dosage may lead to copper deficiency and other adverse effects [NIH ODS].
How it works
Think of zinc as a gatekeeper for your immune system and cellular repair. Zinc picolinate is a chelated form, meaning it is bound to picolinic acid, which may enhance absorption [NIH ODS]. Zinc supports over 300 enzyme functions, including DNA synthesis, wound healing, and proper immune cell activity [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this product category. Data not available on specific event counts for this exact product. High zinc intakes (over 40 mg daily) can cause nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches [NIH ODS]. Long-term use of high doses may also lead to copper deficiency, which can cause anemia and neurological issues [NIH ODS].
Our recommendation
Unless you have a diagnosed zinc deficiency confirmed by a healthcare provider, do not take this 50 mg dose daily. A safer dose is 15–25 mg per day for most adults. If you choose to take this product, consider taking it with food to reduce stomach upset and do not exceed 40 mg total zinc from all sources per day [NIH ODS].
