Immune Boosting Supplements for COVID-19

Last week, I wrote about important lifestyle changes that can help boost your immune system. There’s nothing sexy or novel in these suggestions, but they are an important foundation for maintaining your health. All of these tips are designed to help keep you out of fight/flight/freeze mode so that your body’s immune system is not suppressed by chronic high levels of cortisol. You can read that post here.

The second leg of the immune support/cortisol reducing stool is nutritional supplementation. When choosing products to boost immunity, it really depends on whether someone is acutely infected or not. One size does not fit all.

For people who are trying to prevent the virus or minimize the extent of infection (if it’s been transmitted), here are some recommendations that may help:

  1. Sustained release melatonin. It’s complicated, but suffice it to say that melatonin helps regulate the innate immune system and helps minimize the overload of inflammatory mediators that come along with infection. In addition, it may help deepen sleep… and sleep is very healing. 
  2. Glutathione. Glutathione is a little-known but highly essential bodily nutrient. It has a vast array of important functions to support the health of numerous body organs. It is the body’s premier antioxidant and detoxifier, and it is also a great help for immune health. Glutathione can be found in many foods or can be supplemented. If you supplement, use the liposomal form.
  3. Zinc. Zinc plays a role in keeping your immune system by promoting the growth of T helper cells (white blood cells) that target foreign invaders. It also has antioxidant properties that helps your body ward off oxidative damage from free radicals.
  4. Vitamin A 5000 IU daily. Vitamin A (retinol, retinoic acid) is a nutrient important to vision, growth, cell division, reproduction and immunity. I recommend 5000 IU daily of fully-formed Vitamin A (i.e. one of the retinoids like retinol palmitate vs. just beta-carotene). Take it on a full stomach after a fat-containing meal. 
  5. Vitamin D if levels are lower than 50-60 ng/mL. Deficiency in Vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection. Be aware that Vitamin D depletes magnesium, so this needs to be supplemented as well. 
  6. Vitamin C w/bioflavonoids. If you’re looking to deliver a boost to your immune system, Vitamin C is a must and is widely recommended. Vitamin C and other antioxidants help stimulate white blood cell production and produce certain antibodies that neutralize invading bacteria and viruses. The recommended dose is 1000-3000 mg daily in divided doses. 

This list is by no means comprehensive. I’ve chosen supplements that have been known to help boost the cellular processes that support the immune system. 

Good nutrition is important when it comes to supporting your immune system. Here's a list of supplements that will help the cells that fight infection stay strong and healthy: #COVID-19 #immunesystem #virus #coronavirus #VitaminC… Click To Tweet

And finally… we can respond or react to this situation. We ALL feel vulnerable and that vulnerability creates fear. Vulnerability and fear create a vicious cycle that leads to people to try to CONTROL the uncontrollable. But the truth is, there is no amount of toilet paper or hand sanitizer that will create control of this situation. Pandemics have a pattern and take time to pass (and it WILL pass). The only control we have is keeping our bodies as healthy as possible and stepping up to do our part by staying away from others to prevent the spread and help it pass as quickly as possible. We’ve got this!
