An important note

No supplement will cure or prevent disease.

With the 2019 coronavirus COVID-19 pandemic, it’s especially important to understand that no supplement, diet, or other lifestyle modification other than physical distancing, also known as social distancing, and proper hygiene practices can protect you from COVID-19.

Currently, no research supports the use of any supplement to protect against COVID-19 specifically.

Food Fix: Immune System Boost

1. Citrus fruits

Most people turn straight to vitamin C after they’ve caught a cold. That’s because it helps build up your immune system.

Vitamin C is thought to increase the production of white blood cells, which are key to fighting infections.

Almost all citrus fruits are high in vitamin C. With such a variety to choose from, it’s easy to add a squeeze of this vitamin to any meal.

Popular citrus fruits include:

• grapefruit

• oranges

• clementines

• tangerines

• lemons

• limes

Because your body doesn’t produce or store it, you need daily vitamin C for continued health. The recommended daily amountTrusted Source for most adults is:

• 75 mg for women

• 90 mg for men

If you opt for supplements, avoid taking more than 2,000 milligrams (mg) a day.

Also keep in mind that while vitamin C might help you recover from a cold quicker, there’s no evidence yet that it’s effective against the new coronavirus, SARS-CoV-2.
