What is zinc?

Zinc is an abundant trace mineral that is used in every cell in your body. It is vital to many body systems because it is involved in the growth of new cells and is present in numerous enzymes. It also helps with the processing of nutrients from your food and is even involved in the healing of wounds.

Although it is a crucial part of our bodies, we can’t make it ourselves, and some people find it hard to get enough in their diet. This is most common among people with restricted diets or pre-existing health conditions. The symptoms include rashes, diarrhoea, slow healing and impaired growth and development.

The Benefits of Zinc

Zinc plays an essential role in maintaining good health. It can boost your immune system and is often suggested as a way to help your body fight off colds. After several studies, it was concluded that the studies show a reduction in symptoms if the zinc was taken after symptoms developed. If participants took it for five months, the incidences of cold symptoms and time off work was decreased.

However, it was also decided that not enough was known about the correct dose or the potential side effects to recommend it as a cold treatment. The broader effects on the immune system appear to come from its ability to stimulate some immune cells and reduce oxidative damage by free radicals.

About 5% of the zinc in your body is in your skin; it is crucial to wound recovery and taking supplements or applying it directly to the area has been found to speed up healing. Having enough zinc is also linked to overall signs of good health. It has been linked to skin health, a reduction in inflammation and is often used to support continued good health in the elderly.

What are the different forms of zinc?

Zinc can be found in numerous forms and each has a distinct effect. Some of the most common are:

Zinc sulfate – This is a water-soluble form of zinc which is easy to ingest, but it often remains in your blood, then passes out in urine without increasing the zinc levels in your body.

Zinc acetate – is a form commonly used to boost the immune system. It’s also known as zinc diacetate or zinc salt dihydrate and is used for a wide range of health conditions

Zinc citrate – combined with citric acid this is most easily absorbed, and it’s an excellent way to build up your level of zinc.

Zinc Picolinate-This form is attached to amino acids meaning that your body can recognize it quickly and absorb it effectively. This is often considered to be the best way to raise your zinc levels quickly.

Chelated zinc- This is a process by which zinc is bonded to another substance to make it more easily absorbed. One example is when it is combined with glycine to form zinc bisglycinate.

Are there any side effects?

Taking too much zinc or if it builds up in your system over time can cause toxicity. Many individual factors have an impact on when toxicity may occur, but the NHS recommends that taking less than 25mg per day will keep you within safe levels.

Too much can affect how your body absorbs other minerals. The most common symptoms of zinc toxicity include nausea, diarrhoea, headaches, poor immune responses and stomach pain. If you have any concerns about taking zinc or if you experience any symptoms, it’s vital to stop taking any supplements and speak to your doctor.
