Your immune system is your body’s natural defense to toxins, viruses, and impurities that can make you sick, and may even kill you. The stronger your immunity, the less likely you’ll be struck down by the common cold, the flu, and, yes, COVID-19. However, most people have no idea what they should be doing to fortify their immune system. In this article, we drill down on the best foods and supplements for immune support.

Foods That Boost Immunity

Your first line of defense should be to boost your immune system with food. Most people know that fruits and vegetables that contain antioxidants and phytochemicals are good for immunity, but they fail to appreciate the bad effect that sugar has on their immune system.

Sugar boosts insulin levels which, in turn, decrease the levels of white blood cells in the body. It can also result in an overgrowth of yeast and bacteria. The interaction of stress and other hormones can also inhibit the natural functioning of the immune system.

The best way to reduce the effects of sugar on your immune system is to choose your foods in accordance with the glycemic index. Select low-glycemic carbohydrates, fruits, and vegetables to supply the nutrients that your immune system needs. Here are a dozen of the best immunity-boosting foods:

  • Citrus fruits
  • Bell peppers
  • Broccoli
  • Garlic
  • Ginger
  • Spinach
  • Yogurt
  • Almonds
  • Walnuts
  • Kiwifruit
  • Papaya
  • Chicken

Water as an Immunity Booster

You know how important water is to your health and well-being. Go without it for a week, and you’ll die! What you may not fully appreciate is how vital keeping yourself well-hydrated is to your body’s immune system.

Among its many other jobs, water transports toxins and waste products away from your cells. When you are lacking in water, the ability to remove these impurities from your body is compromised.

Water also replenishes the lymphatic system, which contains antibodies and white blood cells. In addition, water is the major mode of transport around the body, carrying nutrients and oxygen. Unless we are well hydrated, every function will suffer.

Make it your goal to drink half a gallon of water (2 liters) every single day. To start off right, when you first get up in the morning, drink at least 8 oz (250 mls) of water.

Should I Be Taking Vitamins?

Do you really need vitamins? The answer is yes, but with a qualification.

Supplements are by their very definition intended to be an adjunct to a healthy diet. Unless you are covering all of your nutritional bases with a macronutrient-balanced diet that delivers the protein you need for muscle gain, the carbs for training energy, and healthy fats that promote fat loss, you will simply be wasting your money on supplements. So, get your nutritional basics sorted out before you start spending money on supplements.

Working out places a lot of stress on the body. In order to meet those demands and undertake the bodily repair and recovery that is needed, exercisers need more nutrients than sedentary people. Even when you are following a healthy, balanced diet, there are a number of nutrients that you probably won’t be getting in sufficient quantity to meet your body’s needs.

The Importance of Sleep

Sleep is a natural immunity booster. You have probably experienced its power yourself. When you’ve been down with a cold or the flu, sleep is your most powerful healer. When you sleep, your body gets to rest and repair itself. Research also indicates that the more hours of sleep you can get each night, the more efficient your immune system will be. Conversely, when we fail to get enough sleep, we severely compromise our immune system.

Getting into a habitual pattern of quality sleep for 7–9 hours each night is the most important thing you can do to boost your immune system.


Learning how to strengthen the immune system is more important in today’s pandemic climate than it has ever been. Your first strategy when it comes to fortifying your immune system should be to ensure that your diet is packed with such immune system–boosting foods like citrus fruits, nuts, berries, and cruciferous vegetables. Make sure, too, that you are drinking around half a gallon of water each day.

When it comes to supplements, we recommend those that contain vitamin C, zinc, selenium, elderberry, and turmeric. Three of the best immune-boosting supplements on the market right now are VIRUTech Immune Instant and Shroom Tech Immune from Onnit Supplements and 1AND1 Shield Immune Support.
