The immune system is the key to your overall health and especially now during a global pandemic, everyone is wondering how they can strengthen their immune system.
According to the Cleveland Clinic, the
immune system is a network of organs, white blood cells, proteins (antibodies),
and chemicals. It works to protect your body from bacteria, viruses, parasites,
and fungi that cause infection and illness.
But since our
bodies are different, that means our immune systems are different, too. “Signs that a person has a weak
immune system is truly individual,” explains Maya Feller, MS, RD, CDN, of
Brooklyn-based Maya Feller Nutrition. “If you are experiencing significant
systemic changes or onset of symptoms, it is important to seek out the help and
guidance from your primary care provider or specialist so they can help
determine the appropriate course of action.”

VITAMIN D
and COVID-19
We have known
for a long time that it is important to maintain healthy Vitamin D levels for bone health, cardio metabolic health, and
a strong immune system.
There is
emerging evidence that Vitamin D deficiency may be relevant to the risk of
developing COVID-19 infection and to the severity of the disease based on
information from Dr. Joanne Manson, Professor of Medicine at Harvard Medical
School. It was found that there was about an eight-fold higher risk of
having severe illness among those who entered with Vitamin D deficiency
compared with those who had sufficient Vitamin D levels.
Additionally,
a recent publication in the British Medical Journal indicated that those
participants in a study who had normal Vitamin D levels had a 70% lower risk of
respiratory infection than those with significant Vitamin D deficiencies.
It is important to be outdoors and
physically active, while maintaining social distancing. This will lead to
increased synthesis of Vitamin D in the skin, just from the incidental sun
exposure.
It is recommend
to begin dosing with 5000 IUs (125 mcg) a day; people with autoimmune diseases
should probably start with 10,000 IUs a day,” says Steven Gundry, MD, author, medical
director at the International Heart and Lung Institute, and founder of
GundryMD. Sources for Vit D information at www.VitaminDCouncil.com
VITAMIN C
Rationale for Using
Vitamin C in Patients With COVID-19
Vitamin C (ascorbic acid) is a water-soluble vitamin that is
thought to have beneficial effects in patients with severe and critical
illnesses. It is an antioxidant and free radical scavenger that has
anti-inflammatory properties, influences cellular immunity and vascular
integrity, and serves as a cofactor in the generation of endogenous
catecholamines.
Because humans may
require more vitamin C in states of oxidative stress, vitamin C
supplementation has been evaluated in numerous disease states, including
serious infections and sepsis.
Because serious
COVID-19 may cause sepsis and acute respiratory distress syndrome (ARDS), the
potential role of high doses of vitamin C in ameliorating inflammation and
vascular injury in patients with COVID-19 is being studied. Consuming foods and
nutrients with Vitamin C has shown to help in recovery by its positive impact
on cellular repair.
Vitamin B Complex
“B vitamins—particularly vitamin
B6, vitamin B9 (or folic acid), and vitamin B12—support
strong immune function,” explains Serena Poon, CN, CHC, CHN, chef,
nutritionist, and founder of the Culinary Alchemy program.
“A deficiency of vitamin B6
is associated with a decrease in antibody production among other immune
system–weakening functions. A deficiency in vitamins B9 and B12
can ‘drastically alter immune responses’ through a variety of processes.
Vitamin B12 is solely found in animal products, so a
vitamin B12 supplement is particularly important if you are a vegan or
vegetarian.”
Zinc
Zinc is an essential mineral that must
be consumed via diet and that you need to consume it daily since the body lacks
the ability to store the mineral. “Zinc supports the functioning of immune
cells like neutrophils and macrophages,” she explains. “As a result,
a zinc deficiency can lead to a higher risk of infections.
Zinc is thought to potentially drive
down the duration and severity of symptoms associated with the common cold by
preventing the entry of the virus into cells and stopping it from multiplying
in the body.”
Vanessa Rissetto, MS, RD, a registered
dietitian nutritionist and co-founder of Culina Health, adds that zinc can help
symptoms like nasal congestion, nasal drainage, sore throat, and coughing.
Prebiotics and
Probiotics
The digestive system and the immune
system are interconnected, and a balanced digestive system is crucial for
immune function.
Along with eating a diet rich in
vegetables and fruits, adding probiotics to your diet can support your
digestive tract by adding good bacteria that supports a balanced microbiome.
Prebiotics are fibers that act as fuel for probiotics.
N-Acetyl Cysteine
NAC
This supplement that supports
detoxification, respiratory health, and muscle recovery after workouts. NAC is
a precursor to glutathione, the body’s most powerful antioxidant particular for
the liver.
Astragalus
This plant has been used in Chinese
medicine for thousands of years, and has many evidence-backed benefits,
including immune support, heart disease and diabetes prevention, and increasing
strength and stamina.
It’s important to note that people who
are on immunosuppressants, anticoagulants, and diuretic medications should not
take astragalus.
Final Thoughts
About Immunity.
Leaky Gut Syndrome or as it’s referred
to in medical literature, “increased intestinal permeability” is a recognized
risk factor for autoimmune dysfunction and considered by many professionals
a hidden epidemic.
More than ever, its vital that we focus
on a healthy gut lining by reducing any gut permeability, as experts
feel this is the foundation of a strong immune system. Most nutritional experts
recommend focusing on removing inflammatory foods, repairing the gut lining
with medical foods and nutrients, and restoring a proper bacterial balance.
