Zinc has long been a topic of interest, especially during the colder months when people start thinking more carefully about their diet. Zinc is an essential mineral with an authorised claim on the GB Nutrition and Health Claims Register: zinc contributes to the normal function of the immune system. As a natural health shop in Bedford, we’ve seen many customers ask about zinc at this time of year, so here’s a plain look at what zinc is, where it comes from, and how to choose a supplement sensibly.
What Does the Research Say About Zinc?
Zinc is an essential mineral that the body can’t make on its own, so it must come from food or supplements. On the GB register, the authorised wordings include “zinc contributes to the normal function of the immune system” and “zinc contributes to normal cognitive function”. Beyond that, research continues into how the body handles zinc. One paper highlights how genetic differences in zinc transport can affect how well the body uses zinc, which may explain why some people are more vulnerable to low intakes. Another study looked at how different forms of zinc, like zinc citrate or picolinate, are absorbed and used by the body. The results suggest that the bioavailability of zinc can vary depending on the form and other dietary factors.
Research also looks at how different zinc forms compare. For example, a study on sheep found that certain forms of zinc, like potentiated zinc oxide, had better absorption and retention than others. This suggests that the way zinc is delivered can make a difference in how well the body uses it. However, it’s important to note that these studies were conducted in animals, and more research is needed to fully understand how these findings apply to humans.
How Can You Get Enough Zinc?
Zinc is found in a variety of foods, including meat, seafood, legumes, and nuts. However, for those who may not get enough through diet alone, supplements can be a useful option. At Pumpernickel, we stock several zinc-containing products, and we’re always happy to talk through the labels with you. Our Optibac Probiotic Gut Health Gummies include zinc along with vitamin D and calcium, while our FSC Zinc (Picolinate) with Copper is a targeted supplement for those looking to keep an eye on their intake.
For those who prefer a liquid form, our Zincatest 100ml is a convenient option, and for children, the Animal Parade® KidZinc® Lozenges come in a tasty, child-friendly format. Whichever you choose, check the label for the amount of zinc per dose and the form used, and feel free to ask us if anything is unclear.
Things to Keep in Mind with Zinc
Zinc supplements are widely used, but it’s worth knowing that some research suggests high levels of phytate, found in plant-based foods, can reduce the body’s ability to absorb zinc. This means that if you’re relying on a diet high in whole grains, legumes, or seeds, you may want to be mindful of how much zinc you’re getting. A 2026 study also raised questions about potential interactions between zinc and certain compounds, so it’s always wise to consider your overall diet and any other supplements you’re taking.
As always, we recommend speaking to your GP or pharmacist if you’re taking any medication or are pregnant, as they can provide guidance tailored to your individual needs.
