Bioavailable Zinc Forms
Quercetin + L-Histidine
Added Copper for Balance
Resveratrol Antioxidant Support
Our formula includes two forms of zinc: Zinc Bisglycinate, a chelated form bound to the amino acid glycine, and Zinc Picolinate, known for its bioavailability and stability. This combination helps support zinc absorption and utilization in the body.*
Quercetin functions as a zinc ionophore, which means it can help facilitate zinc’s movement across cell membranes. This may support cellular zinc uptake, an important factor for immune and cellular function.*
L-Histidine, an essential amino acid, works alongside zinc to help carry it into cells, supporting better absorption and function.*
Zinc and copper work together in many enzyme-driven processes in the body. Because high levels of zinc can interfere with copper, we include Copper Bisglycinate Chelate to help maintain healthy mineral balance.*
Resveratrol, a plant-based antioxidant, may help protect cells from oxidative stress and support the function of minerals like zinc and copper.*
Our quality assurance process for our nutritional and supplement products begins with collecting, from our suppliers, Certificates of Analysis (COAs) for our ingredients. We then retest the final product blend. We share our COAs because we believe the results are worth sharing.

"I like this zinc because it doesn’t hurt my stomach if I take it on an empty stomach and that it has copper in it because zinc can lower your copper levels. This is why I love JI products because they think of these things and add ingredients it into the supplement"
