Celtic Oysters are the ocean's answer to a multivitamin. They are an amazing source of vitamin B12, as well as key minerals such as copper, iodine and selenium. However, they are most known for being the number one food source of zinc, which is vital for immune function, metabolism, wound healing, taste, smell and hormonal health. See below for a deeper dive into the beneficial nutrients within oysters. We sustainably harvest our Celtic Oysters from clear, unpolluted waters off the southern and western seaboard of Ireland and gently freeze dry them to maintain their fragile nutrients. We then encapsulate them for your convenience and to remove the taste.
