Top Supplements to Help Battle Covid-19

If you want to stay resilient against infection, adding a few immune support products, such as Vitamin C, Vitamin D, Quercetin, Glutathione/NAC, Zinc, and Melatonin can help.


A mere six days after the country hit 18 million Covid-19 cases, we've now surpassed the 19 million mark. The US's case numbers more than doubled in less than two months, a staggering rate of increase. Unfortunately, death rates in the US are also on the rise, now totaling more than 332,000. That equates to more than one death per 1,000 Americans.

The recent development of the Covid-19 vaccine has brought a new wave of hope. However, according to the Washington Post, the general public will probably have to wait until late March or April to receive the vaccine. In the meantime, we must continue to enact public health measures to reduce the spread of the Covid-19 virus, such as washing hands frequently, wearing a face mask while in public, avoiding crowded spaces, and more.

If you want to up your defenses against Covid-19, consider adding some nutritional supplements to your daily routine. Blue Sky Vitamin, developed by Dr. Ron Ledoux, has all of your supplement needs covered.

Vitamin C

Vitamin C has long been hailed for its immune-boosting properties. That's because Vitamin C supports cellular function in various immune cells, enhances their ability to fight infections, and is necessary for cellular death, which promotes immune system health by clearing out old cells and replacing them with new ones.

Studies show that Vitamin C supplements reduce the duration and severity of upper respiratory tract infections, like the common cold. A literature review of 29 studies encompassing over 11,300 people found that regularly supplementing with Vitamin C reduced the duration of colds in adults by 8% and in children by 14%. It also found that regular Vitamin C supplements reduced common cold occurrence in individuals under high physical stress by up to 50%.

Another study revealed that high dose intravenous Vitamin C treatment significantly improved symptoms in individuals with severe infections, including sepsis and acute respiratory distress syndrome resulting from viral infections.

Vitamin D

You're probably familiar with Vitamin D as the vitamin you get from the sun. But did you know it is essential for the health and functioning of your immune system? It helps your white blood cells fight off pathogens and decreases inflammation, which studies show helps promote an immune response.

Because our primary source of Vitamin D is the sun and not food, many people are deficient in this important vitamin. Some risk factors for Vitamin D deficiency include living in places with high air pollution levels, living in cold areas, darker pigmented skin, sunscreen use, and no supplement use. Vitamin D deficiency may negatively impact immune system function. One study found that low vitamin D levels are linked to an increased risk of upper respiratory tract infections, such as influenza and allergic asthma.

A 2019 review of studies found that in over 11,300 individuals, supplementing with Vitamin D significantly decreased the risk of respiratory infections in those with Vitamin D deficiency and lowered the risk of infection in people with adequate levels.

This lesser-known supplement has recently increased in popularity for its immune health benefits. More studies are currently suggesting that Quercetin can potentially prevent and treat different diseases, including cardiovascular disease, cancer, and neurodegenerative disease. According to a 2016 overview of Quercetin's properties, it is known for its anti-inflammatory, antihypertensive, vasodilator effects, antiobesity, antihypercholesterolemic, and antiatherosclerotic activities.

Research has shown that Quercetin has both antibacterial and antiviral properties. It has demonstrated antibacterial effects against almost all strains of bacteria, while its anti-infective and anti-replicative ability may contribute to its antiviral characteristics. These factors make it an ideal supplement for warding off infections and sickness.

Additionally, Quercetin acts as a natural anti-histamine by preventing the release of histamine from mast cells (allergy cells) and other allergic substances. This makes it a beneficial supplement for those experiencing seasonal allergies.

NAC (N-Acetyl Cysteine) is essential for the production of Glutathione, one of the body's most important antioxidants. Antioxidants neutralize free radicals that damage cells and tissues; thus, Glutathione is essential for immune health and fighting cell damage.

NAC can help treat symptoms of respiratory conditions by acting as an antioxidant to replenish Glutathione levels in your lungs. This reduces inflammation in your bronchial tubes and lung tissue. NAC also acts as an expectorant, helping to loosen mucus in air passageways.

Studies have shown NAC supplements can help those suffering from a chronic obstructive pulmonary disease (COPD), which causes long-term oxidative damage and lung tissue inflammation, causing airways to constrict and inducing shortness of breath and coughing. NAC supplements have been used to improve COPD symptoms, exacerbations, and lung decline.

Another study found that NAC may help treat bronchitis symptoms by thinning mucus in bronchial tubes and increasing Glutathione levels. It can decrease the rate and intensity of wheezing, coughing, and respiratory attacks.

Other studies have shown NAC might help treat other lung and respiratory tract conditions like cystic fibrosis, asthma, and pulmonary fibrosis, in addition to symptoms of nasal and sinus congestion due to allergies or infections.

Zinc is another mineral essential for immune function because it plays a vital role in immune cell development and inflammatory responses. In fact, zinc deficiency significantly impacts your immune system's ability to function properly, resulting in a higher risk of infection and disease, including pneumonia.

Zinc deficiency is widespread, and up to 30% of older adults are considered deficient. Studies show that zinc supplements may protect against respiratory tract infections, such as the common cold. Additionally, studies show zinc supplements can also reduce the duration of the common cold.

It can also help those who are already sick. A 2019 study of 64 children hospitalized with acute lower respiratory tract infections found that zinc supplementation lowered the duration of illness and hospital stay by two days on average, compared to the placebo group.

You're probably familiar with Melatonin as the hormone that helps support sleep, but it also has important immune system benefits. Recently, researchers have found that Melatonin binds to NLRP3 inflammasomes, key receptors associated with covid-19's attack on the lungs. By binding to these receptors first, Melatonin can blunt injury to the lungs from the coronavirus.

According to Feixiong Cheng, a researcher at Cleveland Clinic's Lerner Research Institute investigating the use of Melatonin as treatment, "Melatonin may not directly promote the host defense system against the virus but increase the tolerance of the host to the virus."

"Increase in the tolerance of the host to the virus will reduce the tissue and organ damage of the host and allow the host to survive sufficiently long to develop an adaptive immune response, particularly the specific antibody, and finally kill or help clean the virus from [the] body," Cheng explained.
