Oysters hold more bioavailable zinc than any food on earth, and for good reason! Their immune system relies on a powerful antioxidant called superoxide dismutase (SOD) to neutralize free radicals during immune responses. But to make SOD, they need zinc—a lot of it. That’s why oysters naturally accumulate zinc at levels far beyond any other animal.

The zinc in oysters is bound to natural transport proteins, making it highly absorbable, unlike synthetic or chelated zinc supplements. When you consume whole food oyster powder like OysterVive, you’re not just getting zinc… you’re getting a form your body instantly recognizes and uses to support immune health, antioxidant defense, thyroid function, skin, hormones, and more.
