With the 2019 coronavirus COVID-19 pandemic, it’s especially important to understand that no supplement, diet, or other lifestyle modification other than social distancing and proper hygiene practices can protect you from COVID-19
Note that there are many types of coronaviruses, some of which, like the common cold, cause only minor symptoms — unlike COVID-19, which often results in serious, sometimes fatal symptoms. Here are a few supplements that are known for their immune-boosting potential.
VITAMIN D
Vitamin D is a fat-soluble nutrient essential to the health and functioning of your immune system. Vitamin D enhances the white blood cells that are important parts of your immune defense and decreases inflammation. To increase your vitamin D intake, add these foods to your diet:
- Eggs
- Cheese
- Tofu
- Mushrooms
VITAMIN C
An essential nutrient, Vitamin C acts as an antioxidant. Vitamin C may be particularly helpful in boosting the immune systems of people under major stress. To get your fill of vitamin C, look to these foods:
- Citrus fruits and juices
- Kiwi fruit
- Broccoli
- Strawberries
VITAMIN E
Vitamin E is a powerful antioxidant. Research suggests maintaining ample levels of vitamin E is crucial for maintaining a healthy immune system, especially among older people. To get your fill of vitamin E, look to these foods:
- Wheat germ oil
- Almonds
- Sunflower seeds
- Hazelnuts
- Peanut butter
Zinc
Zinc is an essential mineral involved in the production of certain immune cells. The National Institutes of Health (NIH) caution that even mildly low levels of zinc may impair your immune function. Here are some top food sources of zinc:
- Oysters
- Baked beans
- Cashews
- Raisin bran
- Chickpeas
Omega- 3 Fatty Acids
Omega-3 fatty acids are a type of essential fatty acid known to suppress inflammation and keep the immune system. Try these omega-3-rich foods:
- Oily fish
- Flaxseed
- Walnuts
However, remember that there is no scientific evidence to suggest that any of them can protect against COVID-19 — even though some of them may have antiviral properties. Maintaining a balanced diet, getting enough sleep, engaging in regular physical activity, and not smoking are some of the most important ways to help keep your immune system healthy and reduce your chances of infection and disease.
