Immune Boosting 4 Better Health – What supplements do we recommend?

Many or our patients, colleagues and loved ones have reached out to us to inquire about “ways to reduce their chances” of becoming seriously ill with the corona virus which causes COVID19.

Since this virus is a novel virus (meaning it is new and research on it’s replication and activation in human bodies is evolving daily), we are unable to offer definitive recommendations specific for COVID19. However, it is our passion to inspire ways for keeping your immune system in its best shape as a best defense against viruses.

When our body has an ‘invader’ our immune system produces Cytokines.  These proteins signal the body to ‘start fighting’ (a good thing most of the time).  This ‘fight’ automatically upregulates inflammation in the body and is the primary underlying ‘driver’ for symptoms and how well the body adapts to the ‘invader’.  This is what we call an ‘upregulated immune system’. Depending on how strong the immune system is, and what else might be ‘distracting’ it (poor diet, lack of sleep, stress) decides the level of a ‘burden’ a virus becomes on the immune system.  While there may not be definitive research available yet specific to COVID19, there is a plethory of science backing the following methods to reduce inflammation:

  • Optimize Quality Sleep – Aim at 7-8h of good quality sleep. Sleep is where our immune system gets it’s energy to function optimally, it is when we detox, cortisol drops (ie: rest and digest) and when our pancreas rests to lower insulin.
  • Concious Eating – eat the rainbow, whole foods, less sugar, processed carbs, focus on less boxes, bags, cans)
    • If eating packaged food – read nutrition label for sugar/serving and look at ingredients. Can you read them? Do you know what they’re made of? Avoid dyes, Trans fats, HFCS and sugar substitutes a much as possible
    • For some removal of gluten or dairy can drastically reduce inflammation (top 2 Food sensitivities)
    • The amount we eat is a major factor of inflammation as well. Overeating increases the immune response. This increased immune response causes the body to generate excessive inflammation, which may lead to a number of chronic diseases and less ‘response’ for viruses and bacteria
    • Optimize healthy proteins – try to reduce inflammatory cooking techniques
    • Keep sugar intake to less than 20g/day – read nutrition labels
      • Reducing/removal of high glycemic foods
        • Grains
        • Dairy
        • Desserts, candies, cookies, syrups, etc
        • Often sugar is hiding in our daily beverages
  • Reducing Stress as much as possible – Stress aka ‘fight/flight’ puts us in ‘sympathetic’ nervous system response which automatically reduces immune system function
    • SHUT OFF TV (and reduce reading articles/watching posts on social media about things you can not control
    • If needed reach out for Mental health support – reach out and be honest with loved ones, practitioner, counselors – don’t wait!
    • Think “Frozen” and “Let it go!”
      • Exercise – walk – hike – yoga can be helpful. Exercising is a great stress release for many, but too much can also add to the ‘sympathetic’ nervous system response of fight/flight/freeze which often reduces the immune system’s power
      • Qigong
      • Tapping (EFT)
      • Meditation and yoga-nidra
      • Reading fiction, romance, travel, hobby books
      • Watching comedies
  • Optimize digestion and gut function -Your gut health and your immune system are intricately linked.  Everyone should have at least one bowel movement every day. If there is constipation, diarrhea, heartburn and/or bloating work on correcting this (or reach out to a practitioner to support you).

Are there supplements that help to boost the body’s immune system?   At this time, there are no specific vaccines or uniformly successful treatments for COVID-19. However, emerging research on several specific botanical and nutraceutical agents is promising which can optimize the immune system’s ability to adapt and support the body during any virus.   These are listed below. As always, we recommend you run any supplementation by your medical practitioner.

Vitamin, botanical, supplement Supportive research Supports immune system Reduces viral growth Precautions
Curcumin 500-1,000 mg, 2x daily with food Curcumin has been shown to reduce inflammation and decreases viral activity



Has anticoagulant properties – caution if taking blood thinners
Quercetin 500 mg orally, 2x daily away from meals Quercetin is found in fruits and vegetables and has a wide range of benefits, including decreasing viral growth



Caution in those patients with kidney damage
Zinc acetate, citrate, picolinate, or glycinate; zinc gluconate (as lozenge if possible) 30-60 mg orally daily, in divided doses with food A large body of research shows that zinc has strong anti-viral properties against many viruses. yes


Can reduce overall copper and iron levels in the body if taken long term
N-Acetyl cysteine (NAC) 600-900 mg, 2x daily away from meals


N-acetyl cysteine promotes the production of glutathione, a potent antioxidant that supports immune function. It also reduces the severity of the flu


People taking nitroglycerin should avoid due to risk of extremely low BP and headaches
Vitamin D 5,000 IU orally, daily with healthy fat Vitamin D enhances immune system function, reduces viral growth, and can reduce upper respiratory infections



High doses long term without vitamin K can increase calcium in the bloodstream
Vitamin A 10,000-25,000 IU, daily with healthy fat Vitamin A is anti-inflammatory, enhances immune function, and supports the lining of the respiratory tract



High doses long term can increase risk of bone loss and pain in joints and bones
Vitamin C 1-3 g orally, daily with food Vitamin C contributes to immune defense by supporting various cellular functions of the immune system. Vitamin C has been used in hospital ICUs to treat COVID-19 infection



High doses may cause diarrhea and insomnia

Avoid doses >1,000mg/d with history of oxalate kidney stones

Melatonin 5-20 mg, taken at bedtime with or without food In addition to promoting restful sleep, melatonin has been shown to reduce inflammation



Potential for daytime sleepiness depending on dosage and hours slept
Selenium 200-400mcg in divided doses with food Inhibits pro-inflammatory pathway and reduces viral replication



High doses long term may lead to hair/nail loss, tremors, nerve damage and kidney issues.
Juice Plus (dehydrated fruits and vegetables) with food Improves Immunity while lowering oxidative stress



Fasting Mimicking Diet(5 days/month for 3 months)
Offers anti-inflammatory effects and may contribute to alleviate autoimmune disorders as well as immunosenescence by removing old damaged cells and replacing them with young and functional ones.


Not recommended for Diabetics or anyone under 18 years old

Micheal Annantuonio – 36 years old

“After suffering for over 2 years and seeing many practitioners (who often dismissed my fatigue & pain) Dr Zub adjusted my medications and supplements. As a result, my baseline functioning and health is finally better. Dr. Zub works as a partner with you the patient, is earnest, humble and actively learning She is a Gift!”

“I feel like I have finally found a physician who is willing to work as a partner with me with the goal of improving my health. Dr Zub is an outstanding physician both from a diagnostic and a Functional Medicine perspective. I’ve recommended her to many of my friends.”

Karen Bird – Needham MA

“In a very short amount of time, Dr. Zub has been able to identify and address underlying chronic health issues that I have been dealing with, that other doctors were unable to do. I love 4 Better Health’s approach to treat the entire person thru a therapeutic partnership and get to the root of issues, not just throw medicine at a symptom. I truly sing her praises and have already referred others to the practice. I truly wish I had found Dr. Zub a long time ago as she has been life changing!”

Linda LaCamera(1)“Finding 4 Better Health was a blessing after many years of traditional medicinal doctors /Endocrinologists being unable to get me to feeling optimal. Dr Zub listened to me, truly heard me & devised a proactive plan for me to have a better life. My body is still healing, but I am no longer barely functioning to get through my daily life. I can exercise again without being completely depleted of energy. I have been able to successfully lose 20 pounds. I feel I can always contact Dr. Zub with any questions or concerns I may have. We continue to work together to find the right course of action for my health. I can’t say enough great things about their practice.”

Thank you, Dr. Zub, for taking a genuine interest in each aspect of my life affecting my health and vitality; and for taking the time to educate me on the ways in which my body functions on a metabolic level, and the things I can do to better manage my energy and well-being!”

Colleen Adams

“Prior to working with Lisa I’d have to be home-bound one day every other weekend in order to deal with my problem. Now that I don’t need to do that anymore I’m back to hiking/mountaineering, kayaking, bike riding, snow-shoeing, being with friends, and spending time in the White Mountains. I am soo thankful for all 4 Better Health has done for me. You had a MAJOR hand in getting me back into this kind of shape [and I’m looking forward to getting even stronger and more fit]. I feel in command of my life again and I am enjoying doing all the outdoorsy, active things I love to do! What a gift you have given me!”

John Curcio

jenweightloss“My weight has always been a fight. I was having trouble sleeping  and walking upstairs because of pain in my hip and knee. I have tried a million diets but in the end I never felt in control of what I ate. When I made the decision to do the cleanse/detox I had my reservations. But it changed me. What I want
to eat and what my body craves. I feel better than I have in years. I am  sleeping better than ever and taking the stairs every chance I get. In 6 months I’ve gone from 265# to 180#. It’s all planning and consistency!”


I was exhausted and in pain- aching from my neck to toes and waking up 4 or 5 times a night. My doctors told me it was just old age. Within a week of taking a few supplements and small changes to my diet recommended by 4 Better Health; my pain was drastically reduced and I began sleeping so much better. I am doing much more than I had been able to do in a very long time, my spirits are better, my outlook is better and I couldn’t ask for anything more. I would recommend this practice to everyone.
