Build A Balanced, Robust Immune System With Science-Based Nutrition

In the Nutrition For Immune Optimization Course, Chris Masterjohn, Ph.D., reveals the exact research-based foods & nutrients you need to revitalize your immune system, lessen vulnerability to disease, and recover quickly if you get sick.

The right nutrients mean you stay healthy longer & recover faster

20%

The average American gets sick 4 to 6 times per year and has a 20% chance of catching the flu [1, 2].

50M

50 million people are diagnosed with autoimmune disease—80% are women [3].

You might be scared of reinfection with COVID-19, a cancer diagnosis, or chronic pain from an out-of-control immune system.
But what if there were specific, well-researched foods that bolstered and balanced your immunity and supported your chances of long-term health?

Discover the most potent foods, nutrients, and science-based strategies for lifelong immune health in the Nutrition For Immune Optimization Course

A malnourished immune system may increase your risk of...

Chronic pain

In one study of 150 patients with persistent musculoskeletal pain, 93% were deficient in vitamin D. Another study found that 86% of over 250 patients with rheumatic diseases, such as osteoarthritis and rheumatoid arthritis, were low in vitamin D [4, 5].

Autoimmune disease

A recent systematic review and meta-analysis of over 60 studies found that those with autoimmune disease had significantly lower levels of zinc in their blood when compared to those without autoimmune disease [6]. Multiple studies show the protective benefits of vitamin A in type 1 diabetes, multiple sclerosis, inflammatory bowel diseases, and lupus [7].

Upper respiratory tract infections

One study reported that low vitamin D levels were connected to a 36% increased risk of upper respiratory tract infection and a 467% increased risk in people with asthma [8]!

Heart disease

A study of nearly 28,000 adults found that higher intakes of vitamin B1 were connected to a 17% decreased risk of high blood pressure, a 9% decreased risk of coronary heart disease, a 14% decreased risk of heart attack, and a 31% decreased risk of heart failure. [9]

Frequent illnesses

Since 1928, vitamin A has been referred to as “the anti-inflammation, anti-infective vitamin,” and low levels are linked to an increased risk of both viral and bacterial infections [10, 11]. Additionally, in a study of 249 COVID-19 patients, those with deficient zinc levels (below 50 mcg) were directly connected to worse symptoms, longer time to reach stability, and higher rates of mortality. [12]

Leaky gut

Vitamins A and D, glutamine, and plant polyphenols are some of the most powerful compounds that support healthy gut barrier structure and function. Deficiencies in vitamins A and D lead to shorter villi length (the microscopic hairlike structures that absorb nutrients in the small intestine) and lower levels of alpha defensins (proteins that protect the intestinal barrier from pathogens), while glutamine is necessary for both the repair and maintenance of the gut barrier [13, 14]`.

Neurodegenerative disease

A recent statistical review of 15 studies found that higher intakes of vitamin E were linked to a 21% reduced risk of dementia and a 22% reduced risk of Alzheimer disease [16].

“A wealth of data show that vitamins A, B6, B12, C, D, E, and folate; trace elements, including zinc, iron, selenium, magnesium, and copper; and the omega-3 fatty acids play important and complementary roles in supporting the immune system. 

Inadequate intake of these nutrients are widespread, leading to a decrease in resistance to infections and an increase in disease burden [17].”

Dr. Chris Masterjohn combines his scientific expertise with out-of-the-box thinking to translate complex science into new, practical ideas you can use to support your journey toward vibrant immune health.

He earned his Ph.D. in Nutritional Sciences from the University of Connecticut in 2012, and worked as a postdoctoral researcher in the Comparative Biosciences department at the University of Illinois at Urbana-Champaign. 

He went on to serve as Assistant Professor of Health and Nutrition Sciences at Brooklyn College, part of the City University of New York before leaving academia to become a full-time writer and independent researcher. 

The power of food and nutrients to maximize immune function has been a personal and professional focus of 
Dr. Masterjohn for over a decade. 

In the Nutrition For Immune Optimization Course, he offers his years of research and expertise in 10 easy-to-implement lessons.

The truth about inflammation 

What you’ve heard is true—inflammation isn’t all bad.

Your immune system uses inflammation as its primary tool to protect you from bacteria, viruses, parasites, and other pathogens that can cause serious harm.

But that’s hard to believe when your joints hurt, you’re dealing with stubborn weight gain from autoimmunity, or you were just diagnosed with heart disease…all driven by chronic inflammation.

The bottom line on inflammation? Balance.

Chronic inflammation is deadly.

Acute inflammation is life-saving.

In the Immune Nutrition Optimization Course, Dr. Masterjohn will show you the exact foods, nutrients, and lifestyle choices you need to bring balance back to your immune system’s most powerful tool.
