@ Felix, I think better to consume zinc rich food. For example, whole grains and milk products are good sources of zinc. Oysters, red meat, and poultry are excellent sources of zinc. Baked beans, chickpeas, and nuts (such as cashews and almonds) contain good amount of zinc.

@Tarafdar....thanks so much

Dear Felix, thank you for posting this interesting technical question. Personally, I would first ask a doctor to check if I have any zinc deficiency. If a deficiency is confirmed, I would consider buying some zinc supplement according to the doctor's recommendation. Suitable zinc supplements are commercially available in large varieties.

Please also note that the are a few closely related questions asked earlier on RG. Thus it might be worth having a look at the answers given to these questions, e.g.

What are some of the organic Sources of Boron and Zinc?

and others.

Moreover, you can search the "Publications" section of RG for term like "zinc supplementation":

https://www.researchgate.net/search.Search.html?type=publication&query=zinc%20supplementation

As you can see from this example you will receive a long list of relevant references which have been posted by RG members, some of them even as public full texts.

Good luck with your work and best wishes, Frank Edelmann
