Zinc has many vital roles in the body. It supports the immune system to work normally and plays a role in protecting cells from oxidative damage. It’s needed for normal bone, cognitive function and fertility and reproduction, as well as maintaining normal vision. It also plays a role in maintaining normal skin, hair and nails, and helps to maintain normal levels of testosterone in men. It’s needed for normal DNA synthesis and cell division, contributes to normal protein synthesis and is needed for the normal use of macronutrients, such as protein, carbohydrate and fat in the body. 

Zinc also contributes to normal growth in children up to three years of age. With so many vital functions, it’s good news that many fish, including clams, cockles, prawns, lobster, mussels, sprats and octopus, provide zinc. Anchovies, crab and oysters, are particularly rich sources.
