5 Supplements to Boost Your Immune System for the Fight Against COVID

It goes without saying that COVID-19 changed the world as we know it. The pandemic increased consciousness of our hygienic routines, our policies as a community, and our overall health awareness. Masks, vaccines, and quarantines also challenged our physical and mental health. Thankfully, we continue to learn more and take steps towards normalcy. COVID won’t disappear overnight, but much like many other illnesses, there are actions you can take to strengthen your body to be in tip-top shape if the fight comes your way. 

Our bodies naturally fight illnesses like COVID through their own built-in suit of armor, so to speak. It is vital to provide that suit of armor with the proper nutrients to keep it operating at max strength. That way, if COVID does come knocking, your body is well prepared for the fight. Research continues to gain new insights, but some results show specific vitamins and nutrients may provide a leg up on preventing contracting COVID. Some supplements may actually decrease the impact of COVID symptoms on your body. 


Quercetin studies continue to be conducted as early results have been positive. Studies have shown that Quercetin may have the capability to inhibit the replication of COVID. Research suggests that Quercetin has antioxidant, antiviral, and anti-inflammatory properties making it a powerhouse for immune boosting. All of these properties could help in the severity of some COVID symptoms. One study showed promising results: Quercetin supplementation may limit the length of your COVID symptoms [1]. Quercetin may have a positive impact on some of the long-term effects that have been associated with COVID as well. So, if you want to prepare your body for COVID or a COVID-related illness, we suggest you add Quercetin to your supplement routine for optimal health.

Vitamin D3

Vitamin D is primarily known as the sunshine vitamin. Research on its role in our overall health is an ongoing process as its benefits continue to be discovered. It was no surprise when research shifted to its potential help during COVID times. Vitamin D supplementation is even being considered in the mental health field, which is especially important due to the pandemic's negative effects on many individuals' mental states.

Over 80 percent of patients with severe COVID symptoms showed to be deficient in vitamin D [2]. Supplementation with vitamin D may strengthen your immune system and provide protective qualities against acute respiratory infections, which could be beneficial when dealing with some of the many symptoms COVID comes with [3]. To maintain your health, add a high-quality vitamin D supplement such as Freeda Vitamin D3


Magnesium is required to create, transport, and activate vitamin D. Which, we know, plays a role in the body's ability to fight illness. When COVID first reached the level of global pandemic, researchers very quickly saw a connection in the severity of the disease with those who have lived in a magnesium-deficient state [4]. A study was conducted where magnesium was included in supplementation for numerous COVID patients. Those who received the magnesium showed a lower risk of requiring oxygen therapy, proving that magnesium may also play a vital role in the fight against COVID [5].

Zinc plays a vital role in our bodies. With potent anti-inflammatory properties and anti-oxidant characteristics, zinc is considered a gatekeeper to the immune system because adequate zinc is required for all immune cells to function [6]. Zinc is commonly associated with treating coughs and colds, making it an imperative supplement for some COVID symptoms. This essential trace mineral also helps activate your T-cells, which call your body's suit of armor to fight, and helps trigger your internal immune response. Try some of our top zinc supplements to keep your immune system strong.

Vitamin C

Vitamin C is an essential nutrient within your body's immune system. Those with vitamin C deficiencies show impaired immunity and are more likely to contract infections and illnesses. Additionally, when your body is fighting infections, your usage of Vitamin C is increased [7].   COVID comes with many symptoms. Some of the most common during the first strain were cold-like symptoms such as cough, chest pain, and difficulty breathing. Vitamin C has been shown to have anti-inflammatory properties and is often suggested to aid in the battle against a cold. It may be able to reduce the severity of COVID symptoms as well. 

Vitamin C is an abundant vitamin within immune cells. Strengthening your immune cells with a proper supply of their make-up keeps your immune system functioning optimally, giving that suit of armor its strongest defense, ensuring that any illnesses that do make it through are significantly weakened.

The benefits of these supplements to your overall health and to help your fight against illness and COVID, continues to emerge. Now, more than ever, you must keep your suit of armor at max defense by giving it the materials it needs to stay strong.
