Boosting Your Immune System – Part 2

Help Protect Against COVID-19

This is the second in a two-part blog post series on ways to boost your immunity. During this time of the COVID-19 pandemic, it is especially important to maintain as healthy an immune system as possible. For those whose immune systems are already compromised, it is even more important to do whatever you can to boost your immunity, so your own system can launch the best defense against any viral invasions.
As I shared in my previous post, I highly recommend seeing an integrative medical doctor, functional medicine doctor, homeopath or other holistic health practitioner like a chiropractor or osteopath who can recommend high quality supplements that you can take to help boost your immune system and any other supplements that would work best for you given the specific conditions you might have.
When you visit your local health food stores, like Sprouts, Whole Foods, Frazier Farms and Nature’s Weigh, you can browse in the immune system section and speak with the customer service people there who will often recommend supplements that have worked very well for them and other customers. Most have a very good return policy.

1. Jillian Kubala’s Recommendations

Jillian Kubala, MS, RD, wrote a blog post about what she thinks are the top 15  best supplements to help boost your immune system. Included in her list are vitamin C, vitamin D and zinc. Garlic, licorice and echinacea are also among her top 15. To find out what the others are, you can read her entire post here. At the end of her post, she offers some cautionary advice:
“Many supplements on the market may help improve immune health. Zinc, elderberry, and vitamins C and D are just some of the substances that have been researched for their immune-enhancing potential.
“However, although these supplements may offer a small benefit for immune health, they should not and cannot be used as a replacement for a healthy lifestyle.
“Maintaining a balanced diet, getting enough sleep, engaging in regular physical activity, and not smoking are some of the most important ways to help keep your immune system healthy and reduce your chances of infection and disease.

Jillian Kubala, MS, RD, from

“If you decide that you want to try a supplement, speak with your healthcare provider first, as some supplements may interact with certain medications or are inappropriate for some people.
“Moreover, remember that there’s no scientific evidence to suggest that any of them can protect against COVID-19 — even though some of them may have antiviral properties.”

2. Naturopathic Doctors’ Recommendations asked six naturopathic doctors to share their favorite foods that can help boost immunity and prevent illness.  Here are the choices of their favorite foods to help both the microbiome and the immune system: ginger, onion and garlic, bone broth, fermented foods, medicinal mushrooms and root vegetables.
Joshua Corn, ND, MS, recommends ginger for its many health benefits:
“This warming food has a variety of benefits during the cold winter months. Ginger has anti-inflammatory compounds that can help ease aching joints and muscles. Ginger tea is great for nausea or upset stomach and can be used after a big meal to promote digestion. Ginger also promotes circulation and warms the body, helping all your fingers and toes stay nice and toasty. One of my favorite recipes that include ginger is a coconut, carrot, ginger soup. Adding to the power of ginger, carrots are packed with vitamin A and C to help boost immune function. The coconut milk in this soup has beneficial fats that can help improve our intestinal and immune health. Ginger is easy to incorporate into soups, stews, curries, or teas so you get a daily dose of spicy goodness.”

Laura Enfield, ND, LAc, discusses the many benefits of using bone broth to support your immune system and for your overall health and well-being:
“In addition, you also receive a healthy dose of collagen, gelatin, and amino acids such as proline, glutamine, and glycine. All of these play a role in boosting the immune system, supporting digestive health and detoxification, and giving us nutrients to stay healthy. Bone broth can be used in so many different ways, it doesn’t just have to be used for soup. I frequently will cook my rice using bone broth, braise veggies in it, drink a cup of it, and yes, add it to soups and stews.”

Michelle Simon, Ph.D., ND, recommends a recipe of root vegetables to help improve the microbiome and immune system:
“I love a good roasted root vegetable medley in the winter.  Chopping up rutabagas, turnips, red and golden beets, purple potatoes, red potatoes, garnet yams, carrots of all colors, kohlrabi, onions, parsnips, you name it and I can put it in the mix.  Toss with a little olive oil, salt, and pepper and top with fresh rosemary for the last half hour of roasting, yum.  And it looks as good as it tastes!”
You can check out in more detail what these and other naturopathic doctors recommended to help keep the immune system strong here.

3. Dr. Eva Detko’s Recommendations

Dr. Eva Detko has written a two-part blog post series on boosting your immunity. In the first part, she emphasizes the importance of stress and how it can affect your immune system. She also writes about how sleep — the quality of it or not getting enough of it — can drastically affect your immune system either in positive or negative ways.
In the second post, Dr. Detko writes about antiviral foods, botanicals, vitamins, minerals and other supplements, essential oils, what she calls “infoceuticals,” among others, that can each have a positive effect on the immune system.
To check out her two posts, go to:

Dr. Eva Detko, from

Dr. Detko also notes that both exercise as well as cold and heat exposure are extremely effective at improving immune function. “One thing for sure, you cannot have optimal health without moving your body. Generally, the less physically fit you are, the more susceptible you are going to be to infections. You can overdo it too so you really do need to make sure you are moving at the right level for you,” she maintains.
She also points out how important it is for the body to be hydrated because a “dehydrated body cannot fight infections particularly well, and most people these days are chronically dehydrated.”  She affirms that “hydration is NOT just about drinking water,” but also about having the “right levels of minerals to rehydrate your body.” In addition to adding some sea salt to your water, Dr. Detko advises those seeking to boost their immunity to use hydrogen water.  A powerful antioxidant, molecular hydrogen is also an antiviral. At her practice, she has an “infoceutical” called Polarity, which she notes “is also very helpful when it comes to rehydration.”

To strengthen the immune system, she recommends taking cold showers for proper cold exposure and using an infrared sauna. She notes that “there is research that shows that you are 30% less likely to catch a virus if you use saunas regularly.” She explains how being exposed to cold showers for brief periods of time can help build immunity and also stimulate your vagus nerve (a phenomenon called hormesis).

Another one of her recommendations is to  gargle with hydrogen peroxide or a strong saline solution. “Coronavirus attaches itself to the throat and mucous membranes first, after which it travels to the lungs,” she explains. “This process takes a few days. So a good preventative measure is to gargle every day.” She notes that “strong gargling stimulates the vagus nerve. And that stimulation can help strengthen your immune function.”

4. Dr. Eric Zielinski’s Recommendations

Dr. Eric Zielinski, who specializes in teaching others how to use essential oils to improve health, wrote a blog post on some simple ways to bolster your immune system.
He writes about the kinds of lifestyles that can inhibit effective immune response. Among them are a poor diet, mental and emotional stress, a sedentary lifestyle and inadequate sleep. He also writes about the very negative effects that sugar has on the immune system. He has some simple but very important recommendations. The areas he highlights for improvement are diet, lifestyle, sleep, supplements and exercise.
He writes about ways to help minimize stress:
“Stress is a major culprit of immune inhibition. Most stresses in the Western world are perceived – our body is reacting as though we are fighting for our lives, but it might actually be financial, interpersonal, or simply not giving ourselves a break. In order to lessen this perceived stress, we might:
  • Practice mindfulness
  • Incorporate meditative relaxation methods, such as yoga
  • Create a more balanced schedule
  • Prioritize adequate sleep

Dr. Eric Zielinski from

Here is what he shares about the importance of getting adequate sleep:
“Without enough sleep, we don’t allow the brain and immune system enough time to interact. Simply creating a period of restfulness before bed and enjoying a full night of sleep can help to bolster the immune system, particularly during times when threats are more likely.”
You can access the entire content of his post here.
He and his wife also share a recipe to help boost the immune system. You can check out their recipe here. If you are interested in learning ways to boost your child’s immune system, you can check out Dr. Zielinski’s article on this subject here.

5. Dr. Amy Rothenberg’s Recommendations

Dr. Amy Rothenberg, who is both a naturopathic doctor and classical homeopath, has written several articles on actions you can take to help you stay safe and well during the pandemic and on how you can nurture a resilient immune system.
You can access her articles on immune system resilience here.
She has written a thorough article on ways to best boost immunity and defend against COVID-19.  She suggests reducing any sugar and processed foods in your diet, while including healthy food choices such as “veggies, fruit, nuts, seeds, fish, poultry, meat, olive oil, whole grains and legumes.”
She also recommends increasing your daily exercise regimen while reducing your stress levels through meditation and other activities: “And if meditation is not your jam, hobbies, making art or music, or zoning out organizing your spice drawer, all that counts for stress reduction, too. Bring in music, more upbeat podcasts, books, positive news outlets. I have been enjoying the weekly sports podcast Only A Game, and Modern Love (a collaboration between the New York Times and NPR), as well as the uber-upbeat Kind World. Consider putting a limit on the amount of screen time you have each day, as it continues to be associated with obesity, poor diet and depression.”

9. Dr. Isaac Eliaz’s Recommendations

Isaac Eliaz, MD, MS, LAc, wrote a post titled, “Antiviral Toolkit: Natural Agents that Optimize Immune Response and Fight Viral Invaders.” In his comprehensive post, he has an array of suggestions ranging from those involving lifestyle, to calming a “cytokine storm,” and using a variety of medicinal mushrooms.
He also recommends some antiviral herbs, including:
  • Chinese skullcap root
  • Licorice
  • Horse chestnut
  • Japanese knotweed root

Dr. Isaac Eliaz – Photo from

In this post, Dr. Eliaz writes about the immune system and what is referred to as a “cytokine storm.”
He explains that “when your immune system detects infectious microbes — like viruses or bacteria — it activates an alarm system. One of the main alarm proteins, called galectin-3 (or Gal-3), starts sending urgent alerts to other immune system cells. In that role, Gal-3 sets off many immune reactions, including inflammation.”
Normally, this response helps the body recognize and defend against invasion. But when it goes into overdrive, it can cause an extreme inflammatory response known as a “cytokine storm.” Dr. Eliaz explains that this kind of a “storm” triggered by infectious microbes can not only cause severe and potentially deadly inflammation throughout the body, but also lead to some very serious health consequences and conditions. Those he cites include respiratory failure, kidney and liver damage and septic shock.

He notes that these “cytokine storms can be especially dangerous in respiratory infections, making it nearly impossible to breathe as the lungs become overwhelmed by inflammation.” He recommends keeping the immune system “balanced and regulated” to avoid these dangerous “cytokine storms” that can lead to “potentially fatal outcomes.”

11. Dr. Paul Herscu

I have written about Dr. Paul Herscu in two previous blog posts. A naturopathic doctor and classical homeopath, he has been following epidemics for many years and provides updates to doctors, homeopaths, students and others whenever there is an epidemic or pandemic.
In his update on April 12, 2020, Part 12 of his update series, he shares recommendations for staying healthy during this pandemic.
In an online webinar I attended about the COVID-19 pandemic, Dr. Herscu explained that anyone who has been treated by a homeopath and who knows what his or her constitutional remedy is can use that remedy to bolster immunity and take it prophylactically about every 10 – 14 days at a 30C potency.
Here is what he also recommends to help prevent getting COVID-19 and to help boost immunity, along withgood public health measures you should take seriously and follow aggressively”:

Dr. Paul Herscu from


  • Cut down on alcohol, sugar and refined foods
  • Vitamin C – 1,000 mgs
  • Vitamin D, 2,000 IU – 5,000 IU, depending on your Vitamin D status
  • Zinc 10-15mg
  • Elderberry (Sambucas nigra) one teaspoon syrup daily
  • Mushroom Immune Formula that has several mushrooms, 2-3 times a week
  • Resveratrol (may work with MERS-Cov) 500mg
  • Go for a walk each day/exercise at home
  • Good rest and enough sleep
  • Stay hydrated
  • Keep in touch with loved ones, for their sake and yours. The health impact of social isolation is also not good!
  • Don’t panic

12. Dr. Will Cole

Dr. Will Cole, a functional medicine doctor, who has a practice in Monroeville, PA, and who also sees patients online, has a number of blog posts on boosting immunity. Some are written by him and others by guest writers.
This one was written by a guest author and reviewed by him suggesting nine ways to help boost immune function, including using an infrared sauna, going out in the sunlight and using Manuka honey. To read the entire post,  you can check it out here.

13. Author Lynne McTaggart’s Recommendations

I also wanted to share that for those whose immune systems have not been able to shield you from COVID-19, author Lynne McTaggart, has several blog posts regarding the effective use of high doses of Vitamin C and intravenous use of Vitamin C to combat coronavirus and also the flu and pneumonia.
In one post, she writes about the work of Dr. Enqian Mao, chief of Emergency Medicine Department at Ruijin Hospital, a major hospital in Shanghai, affiliated with the Joatong University College of Medicine. He is also a member of the Senior Expert Team at the Shanghai Public Health Center, where all Chinese Covid-19 patients were treated.
McTaggart writes: “Mao was no stranger to vitamin C. He’d used it to successfully treat serious infections, such as pancreatitis and sepsis (life-threatening blood infections), for a decade. When Covid-19 first emerged, Dr. Mao immediately recommended intravenous vitamin C for the patients being treated at his facility.

Lynne McTaggart from

“In the event, Dr. Mao eventually treated about 50 patients with moderate to severe illness with intravenous vitamin C, using doses of 10-20 g a day for 7-10 days.”
He reported to some of his prominent colleagues that all his patients improved and had much shorter hospital stays than patients who did not receive the IV vitamin C treatments. Without the IV vitamin C regimen, patients receiving standard treatment stayed in the hospital an average of 30 days.
To read her full article, you can access it here.
In another article she quotes prominent doctors who regard using high doses of vitamin C as a way to cure those with COVID-19. She writes about a Get Well Health Expo she attended in Olympia. She was especially struck by the talks of two of the doctors there:
“Of nearly 50 brilliant talks and demonstrations, two delivered by Dr. Damien Downing, a pioneer in ecological medicine and president of the British Society of Allergy and Environmental Medicine, and Dr. Thomas Levy, a cardiologist and one of the world’s experts on vitamin C, offered the same message: there is a simple solution to the coronavirus, which has gripped the world in fear.
“Dr. Downing was one of a team of orthomolecular doctors (who offer therapeutic nutrition based on biochemical individuality) to put together an effective plan of attack for the coronavirus.”
She noted that he and the others released a statement in late January by the Orthomolecular Medicine News Service. It affirmed that the coronavirus pandemic “can be dramatically slowed or stopped with the immediate widespread use of high doses of vitamin C.”
To read her complete post that provides patient-based evidence of the remarkable way that high-dose vitamin C can help coronavirus patients recover, go here.

14. More Recommendations and Resources for You….

I have offered you a wealth of information to help you boost your immunity and stay safe and well during this coronavirus pandemic. Many of the resources I share mention the importance of making some lifestyle changes to help improve your immune function.
Better sleep, elimination of sugar and processed foods from your diet, eating healthy plant-based foods, reducing or stopping any alcohol intake, getting out in the fresh air and in nature, calling friends and family, exercising and nourishing your heart and soul through meditation and music are just some of the ways to help support your immune system and help uplift your heart.

Using an infrared sauna, doing safe and effective detoxing of your body, doing yoga, stretching, strength training, T’ai Chi or Qigong are just a few of the other ways to help your body, mind and spirit feel better. There are so many online resources and free resources that you can access, many of them for free. I wrote about some of these in a previous blog post.
When you feel better emotionally, you are always helping your immune system feel better too. My mother always used to encourage me to take a vacation from worry. I encourage you to do that as well.
Generally, when you are doing something that you really enjoy, something that makes your heart sing, you are helping boost both your immune system and your spirit. Whether it’s singing, dancing, painting, writing, learning a new language, cooking a new dish, playing with animals or walking in nature, take time to enjoy, replenish and recharge. It is the best medicine for both your soul and your immune system.
