As the colder months approach, it’s important to prioritize immune system health. Luckily, there are a number of vitamins and minerals that can help give your body the boost it needs to fend off potential colds and illnesses.

Here are three key vitamins to focus on during the chilly season.

Vitamin C

Vitamin C is one of the most well-known immune system boosters out there, and for good reason.

According to the National Institutes of Health, this nutrient has been shown to stimulate the production of white blood cells, which are essential in fighting off infections.

There are a number of ways to up your vitamin C intake during the winter. Citrus fruits such as oranges, grapefruits, and lemons are great sources, as are strawberries, kiwis, and red bell peppers.

You may also want to consider taking a supplement, especially if you don’t eat many fruits and vegetables on a regular basis.

Vitamin D

While vitamin D is commonly associated with bone health, it’s also an important player in immune system function. In fact, a lack of vitamin D has been linked to a higher risk of respiratory infections and other illnesses.

You can get vitamin D from a few different sources, including sunlight and certain foods. Fatty fish like salmon and tuna are great options, as are egg yolks and some fortified dairy products.

If you’re concerned about getting enough vitamin D, consider talking to your doctor about a supplement.

Zinc

Zinc doesn’t get as much attention as vitamin C or D, but it’s still a key nutrient for immune system health. Studies have shown that zinc can help reduce the duration and severity of colds, as well as potentially prevent them in some cases.

If you’re looking to up your zinc intake, you can find it in a number of foods such as oysters, beef, pork, and chicken. Vegetarians can also get their fix from nuts, beans, and whole grains.

Like with vitamin D, there are also supplements available if you need a boost.

Final Thoughts

Good overall health is important in keeping your immune system strong enough to fight off colds and other illnesses. In addition to focusing on vitamin C, D, and zinc, be sure to eat a balanced diet, exercise regularly, and get enough sleep.

That way, you’ll be giving your body the best chance to stay healthy throughout the winter.
