Zink-Portal is a German-language health information website focused on zinc, its role in the body, and topics related to zinc deficiency. It explains why this essential mineral matters for metabolism, the immune system, skin, hair, and nails, and provides information about possible deficiency symptoms, risk factors, daily requirements, dietary sources, supplements, and research. Visitors can explore guidance on zinc and subjects including colds, allergies, skin and hair conditions, wound healing, children’s health, pregnancy, fertility, and psychological wellbeing.

The site also offers a zinc-deficiency self-test to help users consider whether they may be at risk, while noting that deficiency can be difficult to identify. Zink-Portal includes a shop and directs visitors to ways to buy Unizink 50, a zinc aspartate product indicated for zinc deficiency that cannot be corrected through diet. Customers can order through the site or find a local pharmacy, including options for collection or delivery, and links to online pharmacies.

The website advises consulting a doctor or pharmacist and reading the product leaflet
