Build Resilient Immunity in 2023

Build Resilient Immunity in 2023

Last month, Dr. Ryan and I had the pleasure of attending a seminar taught by Dr. Dan Murphy, DC. Dr. Murphy is one of the foremost experts on nutrition and functional medicine in the chiropractic profession. He lectured on topics such as brain injury and concussion, nutrition for cognitive and immune system health, the beneficial effects of red laser therapy, and the prevention of dementia and Alzheimer’s disease using nutrition and lifestyle modification.

Perhaps the most impactful topic for me was Dr. Murphy’s lecture on ‘host immunity.’  Host immunity refers to the strength, resiliency, and adaptability of a given patient’s immune system.  The better the patient’s immune system, the more effectively that patient can combat all forms of disease and illness affecting the body. Dietary and lifestyle modifications such as exercise, proper sun exposure, and evolutionarily consistent eating are examples of techniques patients can use to improve their host immunity.

In my opinion, mainstream media does not focus enough on host immunity. Instead, we are told strategies such as staying up to date with the latest vaccine or booster, avoiding close contact with sick individuals, wearing masks in public, or taking medication for any physical or mental stress your body is subjected to. When did we become so weak we had to start relying on all of these external, synthetic inputs to keep us healthy? Since when did being around other people endanger us, rather than strengthen our immune system by presenting our immune system with a wide array of pathogens and creating a more robust immune system? I recall when ‘chicken-pox’ parties were the norm. Each individual has the opportunity to have an extremely strong, smart, and resilient immune system.  

Dr. Murphy suggests a number of vital supplements for optimizing host immunity. First and foremost are omega-3’s and vitamin D.  Aim for around three grams of omega 3’s each day. For many, this means supplementing with a high quality fish oil supplement. Omega 3’s help with the inflammatory balance in the body and foster an environment where immune cells can combat external infections and diseases. Next up is vitamin D.  Your goal should be around 5,000 mg per day. Getting vitamin D from natural sunlight is the best option, however, during the winter months supplementation is often necessary. Nearly every cell in the body, including our immune cells, possess a vitamin D receptor and is positively activated when this hormone is at proper levels. Vitamin D is also great for bone mineral density, memory, and mental health.  

No lecture on immune health is complete without mentioning vitamin C.  Did you know the benefits of vitamin C were first discovered among sailors with scurvy? Scurvy is a connective tissue disease causing gum disease, hair loss, excessive bleeding, and poor healing from wounds and infection. When the sailors were given oranges, which are high in vitamin C, the symptoms of scurvy all but disappeared. Alas, the immune benefits of vitamin C were front page news! Vitamin C has a host of health benefits including reducing the duration of the common cold, helping with the synthesis of collagen so you can have healthy skin, hair, and nails, and acts as a strong antioxidant with some research suggesting anti-cancer and anti-Alzheimer’s benefits. Vitamin C is found in the highest quantity in citrus fruits. If supplementation is deemed necessary, liposomal vitamin C is your best option. Liposomal vitamin C is encapsulated with a fat or lipid coating improving absorption and decreasing gastrointestinal distress.  

The final three nutrients are magnesium, zinc, and vitamin A. Magnesium is a mineral acting as a cofactor in over 600 reactions in the body, and is important for normal immune function, energy production, blood pressure regulation, and blood sugar control. Magnesium deficiency is common in developed countries. Aim for about 300-600 mg per day of magnesium from a whole food source or supplement. If supplementing, I recommend taking either magnesium threonate or magnesium glycinate, since these have the best absorption in the body and brain. Zinc is an essential mineral associated with proper wound healing and immune system function. It is an antioxidant and important for maintaining proper testosterone levels.  I recommend 15-30 mg of zinc daily. Vitamin A refers to a group of chemical compounds composed of retinol and its metabolites. Vitamin A is essential for optimal immune function, and is also important for our skin and vision. Take around 5,000 IU of vitamin A each day.  

Coming up soon, I will take a deep dive into the importance of exercise and sleep for healthy host immunity. At the surface level, a balanced combination of aerobic (endurance) and anaerobic (strength) training will help develop a robust individual with a strong immune system.  Consistent, quality sleep each night is essential for immune health because melatonin benefits the immune system by decreasing inflammatory reactions in the body, notably the ‘cytokine storm’ seen with covid-19. Supplementing with 3-10 mg of melatonin while symptomatic may provide some benefit, however, I do not recommend long term supplementation of melatonin.  Melatonin is a hormone produced by the body, and long term supplementation may decrease our body’s capacity for producing the hormone on its own.  

Make 2023 the year for improving host immunity. With covid-19 in the rearview mirror,  prepare yourself now for any future health crises that may affect our society. If we all commit to focusing more on healthy host immunity, the need for societal wide shutdowns and vaccination may not be necessary!
