Supporting Immune Function

During this critical health crisis, our best defense may be our very own immune system. As an integrative approach, along with medical treatment, I would like to discuss what I would do (and what I have done) to help to maintain my immune function. It all begins with a healthy diet and being properly hydrated (with water). Unfortunately, sugar, alcohol, and other acid-forming (processed) comfort foods may suppress immune function. Supporting the friendly flora in the intestines, with diet, as well as pre and probiotics, can also assist the immune system. I would suggest more of a plant-based diet, since it is more alkaline, and bacteria and viruses may be more likely to thrive in an acidic environment. When ill, and especially for a person with a poor appetite, soup, and an organic egg can provide easily digestible nutrients. This would include the proteins the immune system needs to produce immunoglobulins. I would also take a whole food supplement to provide basic nutrients that are in a better absorbable food form. In addition to vitamin C with bioflavonoids, we should also be aware of the relationship that vitamin D has with the immune system. As more people are sheltering at home and not going outdoors, supplementing with vitamin D3 during this time may also be helpful.

Although not officially FDA approved, there are some supplements that I have used in my nutrition and natural healing practice that may help support immune function. (Anyone can contact me with questions). Elderberry extract, such as Sambucol or Sambucus, may have some benefit. I have also been using a strong liquid echinacea extract, called Natural Immunity, to enhance immune function for over 25 years. Monolaurin, a substance found in coconut oil may also be helpful. Manuka Honey, which can also be used in tea, has been studied for its antimicrobial effects. Oscillococcinum, a homeopathic ingredient, has also been used. Some people may also use oil of oregano and olive leaf extract. Ginger (as a tea) and licorice root extract may also have some benefit. (Some people with hypertension may be cautioned against the use of licorice). 

Temperature checks could be done, however, as with other viral infections, an asymptomatic person (silent spreader) may be more infectious before exhibiting symptoms when the virus is replicating. Symptoms are more apparent, such as fever when the immune system began responding. Fever can be a controversial issue as some people have been conditioned to fear it and suppress it with medications. Fever is a natural defense by the body in response to infections. A fever may be beneficial by stimulating and enhancing our immune system, particularly T-lymphocytes and Natural Killer Cells activity. A fever may also increase the benefits of interferon, an anti-viral protein produced as one of the body’s natural defenses. A word of caution, a fever can be dangerous when associated with dehydration, (especially for children) therefore it is important to consume a lot of fluids, always consult with your physician or your child’s pediatrician.

 Zinc lozenges are popular during the cold and flu season, but overuse can interfere with copper absorption. This may contribute to a microcytic anemia that would mimic iron deficiency. Only take zinc if you are certain that you have a viral infection, such as the cold or flu, otherwise, zinc taken during a bacterial infection, may not be beneficial to us, but rather to the bacteria. 

In general, when going out, not only masks and gloves may be protective, but also consider protective eyewear if you anticipate being in a high-risk environment, such as crowded areas. Viral respiratory droplets can enter through the eyes. It was recently found that the eyes contain a high concentration of ACE2 receptors, which is the preferred receptor for COVID-19.
