Coronavirus, Precautions, and Strengthening the Immune System

Prior to this recent outbreak of the Wuhan coronavirus, it is likely that most people had never heard of this strain of virus even though other forms have caused significant outbreaks in the past. Coronaviruses are a group of viruses that cause diseases in humans and other mammals, birds, bats, and reptiles. When humans are infected most forms of the virus cause mild respiratory infections but, as we have seen with the Wuhan coronavirus, in rare cases a coronavirus infection can be lethal. 

With increased attention, many people are asking what they can do to help protect themselves from a coronavirus. While washing your hands, wearing a mask, and avoiding travel are key precautions, it is also important to focus on building a stronger immune system. In a previous article, I discussed natural approaches to addressing low immune function. With a strong immune system, you are safer from attack by all but the most virulent microorganisms. It is also likely that you would experience fewer colds or viral infections and have better overall resistance to infections. 

The principles involved in boosting your immune system are quite simple. The first goal is to make sure that you provide the immune system with vital nutrients by consuming a health-promoting diet and utilizing proper nutritional supplementation. A deficiency of virtually any single nutrient can significantly impair immunity. The next step is following a healthy lifestyle that includes getting enough sleep and engaging in a regular exercise program. Supplying optimal nutrition and learning to effectively deal with stress go a long way in supporting central control mechanisms to keep the immune system functioning in a peak state. Boosting your immune system not only increases your resistance to colds and flu and other infections but also can help protect yourself against chronic diseases.

Everyone knows how important vitamin D is good for healthy bones, but its role in human health goes well beyond that. Modern research now shows that vitamin D targets over 2,000 genes (about 10% of the human genome) in the human body. It is now known that low levels of vitamin D can contribute to the development of at least 17 varieties of cancer as well as heart disease, stroke, high blood pressure, autoimmune diseases, diabetes, depression, and many more common health conditions. As it relates to preventing the flu, here is what is known:

Since it is estimated that one out of every two Americans is likely to have blood levels below 20 ng/ml, widespread vitamin D supplementation may prove to be more effective and less costly than conventional flu shots. To ensure optimal vitamin D status, recently most health experts, myself included, are advocating daily dosages of 2,000 to 5,000 IU, even in apparently healthy adults. The research definitely supports this higher dosage level, especially during the winter months. 

Liposomal vitamin C is an advanced form of vitamin c designed for better absorption and utilization within the body. Liposomes are small spherical cells that are composed of an outer layer made of fatty acids known as phospholipids derived from either sunflower or soy. Liposomes also have an inner compartment composed of water and water-soluble active ingredients. The water-soluble ingredient like vitamin C is protected within the inner compartment by the liposomal structure. 

The primary advantage of liposomal vitamin C is improved absorption. The ability of our intestinal cells to uptake higher doses of vitamin C has a threshold. That is why higher doses of vitamin C can cause excessive gas and/or diarrhea. The bioavailability of liposomal vitamin C is significantly greater than regular vitamin C, it is taken up into the body at almost double the level that of regular vitamin C. Liposomal vitamin C is often promoted as an oral alternative to getting an intravenous (IV) dosage of vitamin C. Take 1,000 mg once or twice daily for added protection during the cold and flu season.

There are no natural products with proven clinical efficacy against the coronavirus, but there are several that make a lot of sense to provide general support. Here are some of the best considerations:

Wellmune is a beta-glucan from baker’s yeast that has been shown to be effective in preventing upper respiratory viral infections (colds and the flu) in several double-blind studies . Subjects were treated daily with either 500mg of Wellmune or a placebo for 90 days. In one of these study results, the Wellmune group reported:

Monolaurin is a fat found in coconut oil that is also available as a dietary supplement. It exerts some interesting antiviral effects with confirmed activity to viruses similar to coronavirus. Many viruses, as well as bacteria and protozoa (parasites) are enveloped by a protective membrane composed of fatty substances (lipids). Current research indicates that monolaurin dissolves lipids in the fatty envelope, basically disintegrating the organisms’ protective shield and causing them to be easily destroyed by the immune system. Though monolaurin has not been studied on coronavirus, it may have some benefit. The typical dosage of monolaurin in 1,000-1,500 mg twice daily. 

Serratia peptidase or serrapeptase is a digestive enzyme that also helps keeps mucus secretions in an optimal state – not too thick and not too watery. Originally isolated from a bacteria that resides in the intestines of the silkworm, it is also called “silkworm” enzyme as it is what breaks down the cocoon to free the silk moth. In addition to its nonspecific effect on host defenses against infection, serrapeptase was recently shown to exert antiviral effects by digesting proteins that coat the virus. Other proteolytic enzymes, e.g., bromelain, may also be effective. The dosage for serrapeptase is based upon enzyme activity: 80,000-100,000 SPUs twice daily between meals on an empty stomach.

Astragalus root (Astragalus membranaceus) is a traditional Chinese medicine used to treat viruses . Clinical studies in China have validated it is effective when used as a preventive measure against the common cold. It has also been shown to reduce the duration and severity of symptoms in acute treatment of the common cold, as well as raise white blood cell counts in chronic leukopenia (a condition characterized by low white blood cell levels). Research in animals indicates that astragalus apparently works by stimulating several factors of the immune system. In particular, it appears to stimulate white blood cells to engulf and destroy invading organisms and cellular debris as well as enhance the production of interferon (a key natural compound produced by the body to fight viruses). Follow label instructions.

If you have had close contact with someone who is confirmed to have, or being evaluated for, 2019-nCoV infection, you should monitor your health starting from the day you first had close contact with the person and continue for 14 days after you last had close contact with the person. Watch for these signs and symptoms:

If you develop fever or any of these symptoms, it is important to be evaluated by your healthcare provider right away.
