Why is Zinc Good for The Immune System? How Does It Work

The antioxidant zinc is found in different foods and is produced as a dietary supplement. It enables healthy growth and development in children and enhances immunity through several mechanisms. 

So, why is zinc good for the immune system? The article below explains!

What is Zinc?

Before finding out “Why is zinc good for the immune system?”, let’s learn what zinc is:

Zinc is the second most abundant trace mineral after iron and is an essential component of every cell. More than 300 enzymes involved in immune cell formation, metabolism, digestion, brain function, skin health, DNA synthesis, and protein synthesis rely on zinc.

A diet deficient in zinc will impair the sense of taste and smell. One of the enzymes required for these senses is dependent upon zinc.

In summary, zinc plays a huge role in health and well-being. The element presents itself in various food types, which include:

• Shellfish: crabs, oysters, lobsters, clams and mussels
• Poultry and meat
• Fish: flounder, sardines, salmon, mackerel, and tuna
• Nuts and seeds: lentils, chickpeas, black beans
• Eggs
• Dairy goods: cheese, yogurt, milk, and butter
• Vegetables: kale, mushroom, asparagus, and peas
• Whole grain: quinoa and oats

How Zinc Supports the Immune System

Why is zinc good for the immune system? Here are the reasons:

Enhance Immune Response

Zinc is associated with optimal immune response function. Low zinc individuals have fewer T cells that fight infection and almost no thymus, which produces T cells. When they receive zinc, these people's thymuses expand and release immune cells.

Studies are conducted to prove zinc's ability to lower inflammation in the body, which is connected to diseases like dementia, depression, and heart disease. According to a 2013 study by Ohio State University, Zinc 'lures' into cells that fight infection, preventing the immune system from overregulating. A 2017 study by Poland's Jagiellonian University Medical College indicates that zinc possesses anti-inflammatory and antioxidant properties that may prevent disease.

Infection Prevention

Why is zinc good for the immune system? The element supports the immune system by activating enzymes that break down viruses and bacteria's proteins and stop them from spreading. Additionally, it raises the activity of anti-infection cells.

According to a 2017 US study, adding 4 mg of extra zinc to one's daily diet greatly enhances cell health, enhancing one's ability to fight against infections and illnesses. In addition to preventing DNA damage and oxidative stress, zinc prevents chronic diseases.

Wound Healing

Zinc is also involved in tissue regeneration and wound healing by stopping bleeding, fighting infections, forming new cells, and repairing tissues; it also reduces inflammation and edema that result after surgery.

Because zinc is required for the entire healing process and functions at the minuscule cell level, insufficient zinc may hinder appropriate wound healing. A study published in 2017 shows that zinc enhanced the general health and healing speed of sixty patients with diabetic foot ulcers.

Chronic Disease Prevention

Why is zinc good for the immune system? The production, storage, and secretion of insulin depend on zinc. Lack of this element can contribute to insulin resistance and reduce glucose tolerance in type 2 diabetes. Thus, consuming enough zinc may aid in managing or preventing diabetes.

Zinc deficiency also raises the risk of cardiovascular illnesses. In this case, the body will lack support for lowering oxidative stress, controlling blood clotting, and preserving blood vessel structure.

Because of its immune-boosting properties and antioxidant properties, zinc may lower the risk of several chronic diseases.

FAQs

There are a few FAQs you should know before start taking zinc:

1. Who needs to stay away from Zinc?

Some people, such as those who have had stomach surgery in the past or who have received continuous intravenous nutrition, are more likely to have a copper deficit. These people should avoid taking zinc supplements since they may lower copper levels even further.

2. Why is Zinc sold in 50 mg?

According to a 2014 study of 72 people with the progression of age-related macular degeneration (AMD), taking 50 mg of zinc sulfate daily for three months dramatically delayed the disease, protecting patients against vision loss and blindness.

3. Can you use zinc oxide on a daily basis?

Yes. Products containing zinc oxide are usually safe to use regularly, and your daily skincare regimen should include SPF. However, ensure you follow the manufacturer’s and product’s instructions while using.

4. Is it better to take zinc at night or in the morning?

There’s no specific best time to consume zinc. The most effective time to absorb zinc is when your stomach is empty. But if it makes you uncomfortable, take it with a meal or snack. Avoid high-fiber foods like beans and whole grains, as they may reduce your body's absorption of zinc. Because zinc can interfere with certain drugs, avoid taking it right before or right after penicillamine and antibiotics.
