About OystersOysters are bivalve (having two shells) mollusks that are related to clams, mussels, and scallops. They may be served raw, usually sitting on one shell, or smoked, baked, or as the featured ingredient in oyster stew. Oysters are harvested from both Pacific and Atlantic waters.

Oysters might be a superfood that’s good for your health and may even make you feel sexier (and some say it’s a aphrodisiac). They’re an excellent source of zinc, which your body needs for hundreds of different biochemical processes to occur. Zinc deficiency can be bad for your immune system and can inhibit growth. A serving of oysters is also a good source of calcium, potassium, iron, magnesium, and vitamin B-12.
