CBD, the Immune System, and Covid-19


With the threat of Covid-19, many of us are taking extra steps to strengthen our immune systems. These steps can not only protect us, but also the people we love. And since we love you, we’ve gathered the following information to help you take an active stance in supporting your immune system.   

CBD and the Coronavirus

While the effects of CBD are still controversial and under researched, most people agree on its ability to influence immune response and inflammation. According to Dr. Garcia de Palau, a Spanish cannabis clinician, “[cannabis] is immunosuppressive when there is a hyper-immune response, but otherwise it regulates and corrects the immune system. In fact, you could say it functions like the endocannabinoid system, bringing equilibrium to the organism.” This is significant because in severe cases of Covid-19 patients experience an overreaction of the immune system. 

 However, as promising as this sounds, we can’t say for sure whether CBD can calm the hyper-immune response and inflammation associated with Covid-19. Other research even suggests CBD may have antiviral effects, but again, claiming to understand its effect on this novel virus would be careless.

 How CBD Can Help


On the bright side, the International Association of Cannabis as Medicine emphasizes, “There is no evidence that the use of cannabinoids could increase the risk of viral infection.” This suggests continued use of CBD is safe during the coronavirus pandemic. This is important because CBD has a few tried-and-true benefits we could all use at a time like this. CBD’s anti-anxiety and antidepressant properties can be a valuable tool against the weight of our current situation. According to the American Psychological Association, stress weakens the immune system, indicating it’s more important than ever to manage our stress. Finally, CBD’s potential to increase sleep quality takes us to our next suggestion for strengthening your immune system.



A simple way to boost your immune system is to get more sleep. I know, I know… easier said than done. Between anxiety, social media, and streaming services full of binge-worthy content, setting a bedtime requires quite a bit of self control. Here are a few tips that can help: cut caffeine, reduce alcohol intake, and stay active during the day. And now for the kicker - turn off the gadgets! Sleep.org recommends turning technology off at least 30 minutes before hitting the hay. 

 Diet & Vitamins 


Another way to improve immune function is by focusing on diet. Start by increasing your plant-based intake and limiting dietary fats. Here's a list of some immune supporting vitamins you can design your meals around, or get from quality dietary supplements.

  • Beta-Carotene: Found in sweet potatoes, carrots, and green leafy vegetables. Known to boost immune function by increasing disease-fighting cells in the body.

  • Vitamins C and E: Both are antioxidants that destroy free radicals in the body and support natural immune response. You can find vitamin C in red peppers, oranges, strawberries, broccoli, mangoes, lemons, and other fruits and vegetables, and vitamin E in nuts, seeds, spinach, and broccoli.     

  • Vitamin D: Found in fortified cereals, plant-based milks, supplements, and sunlight.  Research shows vitamin D may reduce the risk of viral infections, including respiratory tract infections.  

  • Zinc: Found in nuts, pumpkin seeds, sesame seeds, beans, and lentils and known to help boost white blood cells, which defend against invaders.
