Quercetin is a compound in plants. It is a plant pigment, and it is found in common veggies like kale, radish, and dill. It is a polyphenol that has antioxidant and anti-inflammatory properties in the body. This makes it a nutrient that can have many positive effects. Especially when it comes to the immune system. Research shows that quercetin can decreases histamine activity and reduce inflammation related to allergic reactions. This makes it worth looking at for fighting symptoms related to allergies. For example, it might be useful if you have:

  • Sinus congestion.
  • Mucus in the lungs.
  • Hay fever.
  • Hives.
  • Rashes.
  • Itching.
  • Asthma.
  • Seasonal allergies.
  • Environmental allergies.


Vitamin D is always critical for your immune system. Though it’s most “famous” for its ability to promote calcium homeostasis and bone health, studies show that vitamin D can also:

  • Reduce cancer cell growth
  • Help control infections
  • Reduce inflammation
  • Modulate the immune system
  • Help kill ceratin viruses


Including more zinc in your diet could result in major improvements in your health. Zinc is involved in more enzyme systems than all of the other trace minerals combined.

Over two billion people have a zinc deficiency. There is no functional storage for zinc in the body. So, as soon as you stop getting zinc from your diet, you could be deficient in zinc.

Amazing benefits of zinc:

  • Zinc helps maintain testosterone levels
  • Zinc helps stabilize insulin and lower blood sugar levels
  • Zinc supports muscle repair and regeneration
  • Zinc decreases your risk of thymus atrophy
  • Zinc supports better night vision
  • Zinc decreases your risk of dry flaky skin
  • Zinc decreases your risk of intestinal inflammation


An interesting new study demonstrated that 82% of critically ill COVID-19 patients were vitamin C deficient. Overall, they had 4x less vitamin C than the normal group. In the study, 18% of the group had 8x less vitamin C than normal.

If you don’t have enough vitamin C, you could be predisposed to getting viral infections as well as bacterial infections. Also, if you have an infection, your body’s requirement for vitamin C goes up. This means that people that don’t have enough vitamin C are at risk for more viral infections. Once they have a viral infection, they need more vitamin C to counter it.

Vitamin C:

  • Is an antioxidant
  • It also increases the body’s ability to make antioxidants
  • Supports the immune system
  • It’s crucial in making more phagocytes (which eat pathogens)
  • It’s necessary to make T-cells (which help kill viruses)
  • It increases antibodies (which attack foreign pathogens)
  • It decreases the risk of acute respiratory infection
  • Is a powerful anti-inflammatory
  • It’s especially important if you have an overactive immune system that produces an excessive amount of inflammation
