Douglas Laboratories Zinc Picolinate
Brand: Douglas Laboratories · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Douglas Laboratories Zinc Picolinate is a targeted form of zinc designed for better absorption. Our assessment is that zinc is an essential mineral, but specific data on this exact product’s clinical effects is limited. For general zinc supplementation, the NIH ODS data confirms zinc supports immune function and wound healing, but the provided data does not include specific dosage or efficacy studies for this brand. Data not available on clinical trials for this specific product.
How it works
Think of zinc as a critical cofactor for hundreds of enzymes in your body. Zinc picolinate is a chelated form, meaning zinc is bound to picolinic acid, which may help your body absorb the mineral more efficiently compared to standard zinc salts. The NIH ODS data explains that zinc supports immune cell function, protein synthesis, and DNA repair. However, the provided data does not include specific mechanism details for the picolinate form — only general zinc mechanisms are available.
Safety profile
Based on the FDA adverse event data, there are 592,059 total reports across all supplements, but specific report counts for this product are not available. The NIH ODS data notes that high zinc intake can cause nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. Chronic high doses can lead to copper deficiency and reduced immune function. Data not available on specific side effect reports for Douglas Laboratories Zinc Picolinate [FDA data] [NIH ODS].
Our recommendation
Start with one capsule daily, following the label directions. Because high zinc can interfere with copper absorption, do not exceed the tolerable upper intake level of 40 mg per day for adults [NIH ODS]. Take zinc at least two hours apart from calcium or iron supplements to avoid competition for absorption [NIH ODS]. Data not available on specific dosing for this product beyond label instructions.
