The body cannot produce zinc itself and must obtain it from food or supplements. Zinc is a cofactor in 300+ enzymes and plays a role in immune function, DNA and protein synthesis, cell division, skin, and hormone regulation.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAlthough the body contains only about 2-3 grams of zinc (distributed throughout all tissues), the mineral is involved in an astonishingly wide range of processes. Zinc fingers — protein structures in which zinc plays a central role — are essential for reading and replicating DNA. In addition, zinc is a component of, for example, superoxide dismutase (an important antioxidant enzyme) and plays a role in the production and storage of various hormones, including insulin and testosterone.\u003c\/p\u003e\n\n\u003cp\u003eIn food, oysters are the densest source (up to 39 mg per 100 grams), followed by meat, legumes, nuts, seeds, and whole grains. Plant-based sources contain phytates which can reduce zinc absorption — this is a point of attention for vegetarians and vegans. Soaking, sprouting, and fermenting beans, grains, and seeds reduces the phytate content and improves absorption.\u003c\/p\u003e\n\n\u003cp\u003eAn important nuance in zinc supplementation: high zinc intake over a longer period (\u0026gt;15 mg\/day for months) can lower copper status because zinc and copper compete for absorption.
