However, supplementing with vitamin C is unlikely to prevent a viral or bacterial infection in humans. Like other vitamins and minerals, it supports the immune system should an individual become infected, Calder says.

An average healthy person may not gain much from supplements, Calder says. Also, consuming too much vitamin C—exceeding the 90 milligrams daily dietary allowance for men and 75 milligrams for non-pregnant women—could cause kidney stones.

Like vitamin C, vitamin D has anti-inflammatory properties. Low vitamin D levels have been linked to increased risks of respiratory infections like cold and flu. A recent study suggests that vitamin D supplements can reduce the duration and severity of common colds.

In the context of COVID, however, the role of vitamin D remains unclear. An October analysis found that inadequate vitamin D in the body did not make people more susceptible to COVID or increase their chances of death from the infection.

The authors showed that supplements did not improve severe symptoms in COVID patients. The body produces vitamin D when skin is exposed to sunlight; but the flesh of fatty fish or fish liver oil are also good sources.

Vitamin C also plays a tremendous role in wound healing, which is a huge part of maintaining your immune system by keeping your skin barrier intact, says Simon.

While orange juice may seem like the ultimate vitamin C source, Simon also recommends eating the following foods to get your fill. Vitamin D improves the function of immune cells by reducing inflammation in the body and decreasing the risk of infection, says Simon.

To help maintain healthy levels, aim for at least 15 minutes of sun exposure a day, according to Harvard Health. Foods high in vitamin D include the following. Vitamin E is another fat-soluble vitamin with powerful antioxidant properties to help support immune cell production.

Add these vitamin E foods to your plate to help boost immune health. Think of zinc as an immunity superstar. Not only does it play a major role in wound healing, but it also aids in the development of immunity cells by impacting the growth of T-cells, says Simon.

While a generally balanced diet is usually suitable for your daily selenium intake, low selenium levels have been shown to reduce immune function. Stock up on some of the following selenium-rich foods.

Inflammation is a sign that your body is working overtime to heal or repair itself, but copper plays a huge role in minimizing its effects by neutralizing free radicals, says Simon.

Research shows that free radicals are unstable atoms in the body that can damage cells and cause illness, but copper has antimicrobial properties to reduce their presence and ultimately calm inflammation.

Maintaining healthy copper levels is a bit of a balancing act, however, because too little copper can suppress your immune function, yet too much copper can be dangerous and lead to cell death.

But no need to overcomplicate it because copper toxicity is rare, stresses Simon. Focus on a varied diet by eating some of the following. Studies have shown that probiotics promote natural antibodies in the body by boosting immune cell production and fighting off infection.

Some research even suggests that probiotics can prevent respiratory tract infections like the cold or flu and reduce urinary tract infections in women.

Foods high in probiotics include the following. Andi Breitowich is a Chicago-based writer and graduate student at Northwestern Medill. As a former collegiate pole vaulter, she has a love for all things fitness and is currently obsessed with Peloton Tread workouts and hot yoga.
