8 Supplements to Support Your Immune System During the Pandemic

Vitamins and other supplements in a pharmacy.

Looking to boost your immune system as the world slowly reopens?

You should be!

Having recovered from Chronic Fatigue Syndrome that stemmed from an acute viral infection(s), I’ve learned how deficient we are in many micronutrients and amino acids. Unfortunately, we do not get what we need from the typical “American Diet.

With the pandemic continuing to affect our lives, and with cold and flu season just around the corner, I want to share with you some supplements to help support and optimize your immune system. My list is based on mounting research and evidence supporting their efficacy, which I highlight in my discounted certified online dispensary with Fullscript (20% off everything). 

Studies show that low levels of NAC and Glutathione (along with other pre-existing conditions) have resulted in severe COVID-19 infections. There is also heavily supported evidence on the efficacy of Vitamins C, D3, and Zinc as immune boosters.

Let’s explore the functions and benefits of these supplements one by one.

N-Acetyl-l-Cysteine (NAC)

N-Acetyl-l-Cysteine (NAC) provides cellular antioxidant support and promotes explicitly healthy lung tissue. N-Acetyl-l-cysteine (NAC) is a free radical scavenger that is a byproduct and supports glutathione levels in tissues.

  • Supports cellular antioxidant defense system
  • Promotes healthy lung tissue
  • Used to treat conditions such as asthma and cystic fibrosis
  • Reduces inflammation 


Glutathione is an antioxidant produced in cells. It’s mainly composed of three amino acids: glutamine, glycine, and cysteine. It’s used to treat conditions such as: 

  • Treats asthma 
  • Cystic fibrosis 
  • Reduces inflammation

The value of optimizing your glutathione levels to support your immune system and stave off respiratory infections is quite evident, as glutathione levels may be reduced by:

  • Poor nutrition
  • Environmental toxins
  • Stress
  • Levels decline with age
  • Poor sleep and insomnia 

Several studies indicate that higher levels of glutathione may improve an individual’s responsiveness to viral infections. Endogenous glutathione deficiency appears to be a crucial factor enhancing SARS-CoV-2-induced oxidative damage of the lung and, as a result, leads to severe manifestations, such as acute respiratory distress syndrome, multiorgan failure, and death in COVID-19 patients.

Multiple published studies describe the absorption and functional properties of ReadiSorb Liposomal Glutathione.


Zinc is designed to support the body’s natural defense system, enhances digestion and metabolism of essential vitamins (for example, it affects normal absorption and the actions of B vitamins), minerals, carbohydrates, and other essential nutrients. It is considered an “essential trace element” because minimal amounts are necessary for optimal health. 

  • Supports immune system function
  • Promotes reproductive health

Vitamins for the Immune System

Vitamin D

Vitamin D3 has long played a role in immune health; vitamin D receptors are found on several immune cells, supporting healthy immune cell activation.

  • Supports immune system function
  • Promotes cellular support 

Vitamin C

Liposomal Vitamin C delivers optimal absorption and bioavailability. It also provides the following protective factors: 

  • Antioxidant protection
  • Immune support
  • Supports the production of healthy connective tissue and collagen

Super Herbs with Anti-viral Properties
