What do I do to protect myself during cold and flu season?

In general I like to give my body all the important building blocks or components to run optimally. So often today, because of over farming and depleted soils, our foods are deficient in essential vitamins and minerals. I believe it is more important to supplement today.
Keep in mind that quality supplement matter. Do your research on supplement companies. Not all areas in the world have the same level of quality or the same farming or organic standards. Avoid solvents or additives and look for bioavailable, methylated, and buffered options. Aim for powder, liquid, or capsules rather than tablets as tablets can contain more additives. Where are the ingredients sourced, how are they extracted, what tests are run to ensure purity…
Below you will find supplements, foods, teas, and oils I personally enjoy and use. Please keep in mind the information below is based on literature I have reviewed and for educational purpose only. It is always important to consult with your primary care provider before making any changes to diet and lifestyle especially if you take pharmaceuticals.
Foundational Supplements:
Theses are supplements that I find to be general building blocks to a healthy immune system.
Vitamin C: antioxidant and immune supporting, best taken in divided doses 2-3 times daily. In some instances doctors may use high dose intravenous vitamin C to treat some patients with viral infections (Aslam, 2017, Cheng et al, 2020, Saul 2020, Hunt et al 1994).
Zinc: an essential mineral/trace element is party to more than a 100 enzymatic reactions in the body necessary for a healthy immune system integrity. In particular zinc has direct antiviral properties (Read, S.A., 2019, Fraeker et al. 2000, te Velthuis, A. J. 2010).
Magnesium: a cofactor in estimated 700—800 enzymatic reactions in the body ranging from muscle and nerve support to immune support, and is required to convert vitamin D to its active form (Dean, 2017).
Vitamin D3: Not only helps with calcium absorption and strong bones, it plays a very important role in modulating the immune response. Deficiencies can lead to increased vulnerability to infection and autoimmune disease. Vitamin can be made in the skin through sunshine exposure (though only without sun screen application and without showering). Furthermore, most people in the USA live too far north to get enough direct sunshine rays to make vitamin D even in the summer (Aslam, 2017, Martineau, 2017).
B Complex: Supports many systems in the body including a healthy brain and nervous system as well as supporting biochemical reactions in the immune system (Aslam, 2017).
Omega Complex with EPA and DHA and Cod liver oil with Vitamin A: Beneficial to so many systems in the body including growth, development, and brain health. A good source of vitamin A is important for not only vision but also the immune system (Aslam, 2017).
Probiotics: Supportive of a healthy microbiome and a healthy immune response for most people (those with SIBO may need to be very specific and target which probiotic strains they consume) (Azad et al., 2018, Eguchi, K. et al 2019).
Multivitamin Mineral: Look for a quality whole foods product and/or a product with methyl folate and methyl B12.
Probiotics: Supportive of a healthy microbiome and a healthy immune response for most people (those with SIBO may need to be very specific and target which probiotic strains they consume) (Azad et al., 2018, Eguchi, K. et al 2019).
Calcium (optional): may be a good addition to the diet if one is not tolerant of dairy and does not consume enough green leafy vegetables (green leafy vegetables are an excellent source of calcium and collagen for strong and flexible bones). Plays an important role not only in our skeletal system, calcium also helps in immune response signaling (Grinstein, S. & Klip, A, 1989).

Additional Supportive Supplements:
During certain seasons or circumstances, when stressed, fatigued, or unwell more support may be ideal. Increasing vitamin C, D3, and zinc during times of need is helpful, and considering further support may be warranted as well.
Quercetin: A natural food derived antioxidant that is anti-inflammatory and antihistamine, works most efficiently in combination with vitamin C. Excellent for allergy season, supportive of the cardiovascular system, and antiviral (Anand, 2016, Brenton 2014).
NAC: N-acetal cysteine is a precursor to glutathione which is a major antioxidant in the body, and supportive of the lungs and mucosal lining of the respiratory system. Immune supporting and excellent for those living through wildfire seasons. NAC is also known for breaking down mucus (Healthnotes, 2019).
Silver: Look for colloidal silver or a bioavailable silver in throat spray or nasal spray. Strengthening to the immune system and can repair cellular damage. Anti-viral, antibacterial and anti cancer. (Franco-Molina M.A. et al, 2016, Fatima M et al, 2016)).
Elderberry: rich in antioxidants and vitamins that support the immune system, and antiviral (Zakey-Rones, 2004).
Echinacea: antiviral, antibacterial, and anti-inflammatory, strains of avian influenza, herpes simplex, respiratory syncytial, and rhinovirus strains are all very sensitive to echinacea purpurea. (Hudson, J. 2011).
Resveratrol: antioxidant with adaptive immune regulation. Has been studies for effectiveness against some viruses (Lin, et al, 2017).
Astragalus: adaptogenic, modulates stress, immune supporting and antiviral (Kallon S. et al 2013)
Herb Pharm Rapid Immune Support: source of elderberry, echinacea, and several other immune supporting and adaptogens. Excellent aid when needing to ramp things up.
Boiron Chestal Honey: for Cough & Chest Congestion Homeopathic Medicine. Very soothing when dry or productive cough symptoms are bothersome.
Food as Medicine:
Cinnamon: Antioxidants help to fight infection, is anti-inflammatory, anti-fungal, and blood sugar balancing. (Fatima M. et al 2016, Shen Y. et al, 2012).
Garlic: Antiviral properties may be protective against the cold and flu. Garlic may help prevent and may shorten intensity and duration of infection (Mehrobod, P. 2008/2009).
Oregano: immune supporting, antibacterial and antiviral, oregano culinary herb may be immune supporting and oregano oil is natures strongest antibiotic (Giling, D.H. et al 2014).
Licorice: Immune boosting, stress reducing, supportive of the digestive system, antimicrobial, and antiviral (Wang, L. et al 2015).
Raw Coconut Oil: cold pressed unrefined virgin coconut oil is anti-microbial, anti-viral, anti-bacterial, and anti-fungal (Shilling M. et al, 2013).
I love to make a low temperature slow cook crock pot of soup on a regular basis. Packed full of bone and veggie broth, plenty of veggies (fresh or frozen), onion, lots of kitchen spices, rosemary, sage, thyme, oregano, garlic, ginger, turmeric, sea salt, and sea veggies. I portion this out into quart jars and reheat on the stove throughout the week. After reheating I will add some miso, coconut aminos, raw and cultured sauerkraut, and either a lightly cooked egg, or sprouted quinoa and avocado. Food such as this gets me through the worst of cold and flu season keeping me healthy.

There are any more wonderful essential oils. Always research quality, source, and how an oil is extracted. It is very important do your research as some oils may contain solvents and chemicals. I personally acquire my essential oils from doTerra and I am a Wellness Advocate affiliate of this company.
