Immune Boosting Vitamins and Foods

Updated: Mar 16


Research shows that specific vitamin deficiencies are associated with low immunity. The World Health Organization has declared a coronavirus pandemic. Coronavirus infects the lungs of immune compromised patients that can lead to severe pneumonia symptoms and death. Many people infected by it do not develop symptoms and do not need special treatment. It is a severe problem for the elderly, who have the most vitamin deficiencies along with other coexisting conditions. Smokers and chronic alcohol drinkers also have immune compromised systems. However, I find that most healthy people, ages 20-60, have multiple vitamin deficiencies on their nutrition testing results.

The immune system requires the following vitamins: A, C, D, Zinc, and Glutathione to properly support the body and flush out toxins it comes in contact with. Gluathione inparticularly is good for the lungs and liver. The liver runs two phases of detoxification to remove waste or environmental toxins from the body. Glutathone is required for both of these phases. Please go to my references below to visit research articles on how each of these vitamins support the immune system differently.


Here is a list of foods that contain these immune boosting vitamins:


Vitamin D: Tuna, mackerel, salmon, beef liver, egg yolks, and cheese.


Vitamin A: Beef liver, cod liver oil, sweet potato, carrots, black-eyed peas, spinach, broccoli, and sweet red pepper.


Vitamin C: Broccoli, cantaloupe, cauliflower, kale, kiwi, orange, grapefruit, papaya, red, green or yellow pepper, sweet potato, strawberries, and tomatoes.


Zinc: Organic grass fed meat, shellfish, chickpeas, lentils, beans, seeds, nuts, eggs, and brown rice.


Glutathione: Asparagus, avocado, cabbage, brussel sprouts, spinach, broccoli, garlic, chives, tomatoes, cucumber, almonds, and walnuts. However, a variety of factors can affect the levels of this vital nutrient, including storage and cooking.


You can get these vitamins from the food sources above but many people do not digest and absorb their food optimally. This is called malabsorption. Malabsorption leads to vitamin deficiencies. All chronic illnesses are associated with vitamin deficiencies. There are many natural ways to heal malabsorption but it is important to understand the root cause of why it is happening before simply treating it the same way for everyone. The first, best way to aid in proper absorption of nutrients is by chewing thoroughly. This allows the body enough time to produce enzymes that break down and digest food. So it's important not to rush when eating so that you can absorb all those vitamins you are consuming from your food.


Supplements do not substitute a healthy diet

Supplements can strengthen your body. They can not substitute a healthy diet of fresh fruits, vegetables, and whole grains. These vitamins should be taken in addition to eating foods rich in these vitamins. Supplements support what you might be missing which may be important during this time


To aid in absorption, liposomal liquid versions of these vitamins may be best but capsules also work well. You can also get these vitamins intravenously which go directly in the blood and bypass the stomach altogether. Another vitamin that cleanses the body and supports your mitochondria, the battery of your cells, is called PQQ. I am taking all of these plus PQQ as I continue to travel and see patients.


You can buy all of these high quality supplements on my online dispensary while they still last here: https://us.fullscript.com/welcome/drfelty. For updated coronavirus information, please visit The World Health Organization website: https://www.who.int/. I will post another article on coronavirus prevention. Stay tuned and stay calm. Remember, your body knows how to heal itself when it has what it needs. Making sure you are consuming these vitamin rich foods and supplements enables your body to fight off infections better.
