Oysters are the single richest dietary source of zinc available in nature, and zinc is the mineral most directly tied to testosterone production, immune resilience, and hormonal balance. MK's Oyster Extract delivers concentrated nutrition from wild-caught Irish oysters harvested from the clean Atlantic waters off Ireland's coast, providing zinc and iodine alongside the full spectrum of oyster-native minerals including copper, selenium, and taurine. Four capsules delivers whole-food mineral nutrition that supports hormone health, thyroid function, and metabolic vitality from a source humans have relied on for thousands of years.
