How you or your family member reacts to a virus (or bacteria) depends in great part on the status of your immune system. Secondly, your immune system depends greatly on your nutrient intake – from foods and supplements. Daily habits can play a role in protecting you from getting the virus (e.g. washing hands) but these basic concepts are well covered in the hourly news

A few facts: 

  • A strong immune system is the best defense against all forms of disease including viruses and chronic diseases. 
  • Coronaviruses have been around for hundreds of years. The current strain is different, but all viruses change (mutate) on a yearly basis.
  • About 20% of common colds are caused by a coronavirus. 
  • The latest version of the Coronavirus was first detected in late December in the Chinese city of Wuhan. It has now considered an official Pandemic. Deaths have occurred while many have suffered mild symptoms to more severe symptoms and recovered.
  • Adults over the age of 50 may be at the highest risk and having hypertension may contribute to the more severe cases.


Some natural therapies to enhance the body’s immune system as well as to kill viruses including flu-like viruses, include zinc, magnesium, vitamin C, Vitamin D3, Iodine and of course Glutathione. The key is quality of the products and dosing.

1.Eat healthy foods: lots of vegetables (preferably organic) and some fruit. Variety is key. Avoid sugar, flour, vegetable oils, and dairy products. These foods can weaken the immune system. 

2. Nutrient-dense foods are still the front-line defense for your immune system. 

3. Supplements: As noted above the following supplements are recommended to enhance your immune system. (If you have contacted the Coronavirus, higher doses are often recommended and may include IV infusions of nutrients if available).

Note that the below is my personal regimen and others may recommend more or less and different dosing:

  1. Vitamin D3/K3. 5,000 mg to 10,000 mg generally recommended for adults. 
  2.  Zinc (divided doses 20 mg with food). 
  3. Glutathione (our No. 1 Antioxidant). Vars Cream or Spray form best. 
  4. Magnesium (400 mg to 600 mg daily).
  5. Probiotics (70% or more of your immune system is in your gut). Multi-strain variety. 
  6. Iodine.
  7. Vitamin C (powder if available). (Don’t’ forget organic berries, apples, oranges, and other natural fruits – not drinks). 2,000 mg to 5,000 mg daily in divided doses. 
  8. Methyl B complex or Methyl B12 and Methyl Folate separately. 

Other helpful hints:

Vitamin A, Fish Oil, and other products could be recommended. 

Get plenty of sleep to strengthen your immune system. Regular exercise and fresh air help. Note: If you go to the gym, make sure you use wipes. If not feeling well, stay home. 

Wow! That seems like a lot of supplements. Yes, but in the functional medicine world and in my world, these are ones many of us take every day. It is always a personal choice as to which ones to take, how to eat, and which ones may be more important to you. You should consult with your health care provider – assuming he or she is knowledgeable in the area of nutrition. 

Saying this, it is important to realize that DIET is still at the top of the list. Eating the following will give you the best protection if they are Organic and preferably locally grown:  

Spinach, Celery, Avocado, Mushrooms, Onions, Asparagus, Cauliflower, Broccoli,  Brussels Sprouts, Zucchini, Green Cabbage, Bell Peppers, Berries, Oranges, Apples. 

Why supplement? Today’s food industry is focused on convenience and fast foods, processed foods, nutrient-deficient/depleted foods with added chemicals and preservatives.
