Welcome to our shop, Benefits of Oyster Turquoise Pendant, Like most seafood, oysters are high in protein & low in calories. This shellfish is a good source of selenium, copper, iron, & vitamin B12. They are also very high in zinc, with just one 3-ounce serving more than doubling the daily recommended intake of zinc for adults Thanks for visiting my shop.
