Introducing Oysterzinc, a pure zinc supplement made from fresh oysters — aka the highest food source of zinc! Here to support your immune system with natural, whole-food zinc when you're in need.*

Our Oysterzinc is 100% oyster powder from fresh oysters off the coast of Ireland. Made in small batches from only the meat of the oyster (no shells!). No additives or fillers either.

Our process involves slow, gentle convection drying under a low temperature to preserve bioactivity and nutrient integrity, making for the most potent oyster extract around.*
