With all of today’s medical advances, many diseases are still incurable by available drugs. Even when drugs can cure diseases, they usually come with side effects, sometimes worse than the disease itself.

For example, available drugs today are not able to cure viruses. They merely shorten and lighten the symptoms that are caused by viruses. You recover from illnesses because your own immune system works for you to fight off viruses that cause these illnesses.

Your immune system: The core of your health

When your immune system is strong, you can resist illnesses without a single sniffle. Even when you do come down with an illness, the length and intensity of the symptoms you experience correlate with how strong your immune system is. The stronger your immune system, the lighter your symptoms and the shorter it takes for you to recover.

You can actually nourish and take care of your best doctor in the whole world, your own immune system, so that it works effectively protect your health and fend off diseases.

How your immune system works with amazing complexity

Your immune system is an extremely complex yet well coordinated collection of lymph nodes, organs and cells, all working together, releasing different chemicals at different times.

Your immune system works 24 hours a day to protect you from enemy invaders like bacteria, viruses, parasites, pollution, and even your own dead cells.

Think of your immune system as an army, where different battalions come together, using different weapons to fight enemies.

Main lymphoid organs

Bone marrow and thymus are your main lymphoid organs.

Bone marrow creates red and white blood cells. White blood cells are our immune cells.

Thymus is the training centre of your immune system. Just like how an army trains its inventory, airforce and navy, our thymus trains immune cells called T-cells to perform specific functions.

Peripheral lymphoid organs

Your immune system also consists of peripheral lymphoid organs, such as tonsils, spleen, lymph nodes, and appendix.

For example, swollen lymph nodes under the arm indicate that your immune cells are fighting an infection.

Antibodies: Missiles of the immune system

Your immune cells are very protective, shooting off very specific missiles to invaders at all times. These missiles are called antibodies or immunoglobulins.

When there is bacteria invasion, for example, these cells jump into action by releasing bacteria-specific antibodies, which kill the bacteria.

Macrophage: Garbage man of the immune system

The macrophage is both a messenger and a fighter. When it sees enemy cells, it will call other immune cells to the battlefield. It fights enemies by grabbing and swallowing them.

Natural Killer (NK) cells

There are several types of T-cells that join in the fight against invaders.

One powerful type of T-cell is the Natural Killer (NK) cell. It kills enemies by releasing certain chemicals, for example it can seek and destroy a cancer cell long before it develops into cancer mass that is detectable by human.

The number one reason you get sick

Your immune system is very intelligent and hardworking. It works every second around the clock to protect you from deadly enemies. Without the immune system, you could die in a matter of hours.

But why do so many of us still get such terrible diseases with such an army inside us?

Because we have a malfunctioning immune system.

Invaders get into your body at any second… even a cut in your tongue creates opportunities for infection. Thankfully, your immune system is always working to protect you.

Pollution and dust create risks for lung cancer. Your immune system defends you, but when it becomes weak, cancer cells could start to grow.

There is no effective medicine to prevent diseases. You must depend on your own immune system to defend you and prevent you from getting sick in the first place.

A malfunctioning immune system

Most diseases are caused by a malfunctioning immune system. Your immune system can malfunction in a number of ways.

When your immune system is weak, you can get diseases like flu, infection, hepatitis, or cancer.

On the other hand, when your immune system overreacts, you get allergies and autoimmune diseases.

Autoimmune diseases like Rheumatoid Arthritis and Multiple Sclerosis are examples of a self-attacking immune system. The immune system attacks your own body cells because it can’t differentiate between enemy cells and friendly ones. For example, Rheumatoid Arthritis occurs when the immune system mistakes the joint as enemy cells and tries to destroy them.

How Nutritional Immunology can help your immune system

A malfunctioning immune system can create disaster in the body.

So how do you prevent these diseases from attacking your families? How can you ensure that your immune system is always strong and healthy?

There is a science that can help us. It’s called Nutritional Immunology.

Nutritional Immunology studies the effect of nutrition on the immune system. It goes beyond basic nutrition like protein, carbohydrate, fat, vitamins and minerals. These nutrients are easily available to us today. Instead, Nutritional Immunology looks at three types of nutrients:

  1. Antioxidiants
  2. Phytochemicals
  3. Polysaccharides

Nutritional Immunology studies the types and species of plants with the most antioxidants, phytochemicals and polysaccharides content. It studies the parts of the plants with the most nutrients. For example, grape seeds are rich in OPC, a very powerful antioxidant, and ginseng berry is even more powerful than ginseng root.

Nutritional Immunology also studies the best age to harvest and the best ways to process plants to prevent nutrient loss. For examples, mushrooms must be harvested when young, but cactus is more nutritious when it is older. Soy must be heated well, but cactus cannot be boiled.

1. Antioxidants

Antioxidants help to delay aging. Because your risks of getting diseases increase as you age, a diet rich in antioxidants can help slow down the aging of your cells, tissues, and your immune system.

Antioxidants are the reason why some people have younger biological age than their chronological age. For example, a 50-year-old who regularly consumes foods high in antioxidants can have the immune system of a 30-year-old.

Many different plant foods have high levels of antioxidants.

Grape seeds and rose hips are good examples. OPC, the antioxidant in grape seeds, is 20 times more potent than vitamin C, and 50 times more potent than vitamin E.

2. Phytochemicals

Phytochemicals, also known as phytonutrients, help you prevent all types of diseases.

For example, phytochemicals in cactus help to heal wounds faster. Soy is very rich in phytochemicals that improve cholesterol and suppress cancer.  The phytochemicals in ginseng berry help fight obesity and diabetes.

3. Polysaccharides

Polysaccharides are long chain sugars that prevent cancer or help existing cancer patients to get better faster by activating the Natural Killer (NK) immune cells which go around the body seeking and destroying cancer cells.

Mushrooms are rich in polysaccharides. Some good mushrooms are Agaricus Blazei Mushroom (ABM or Brazilian mushroom), reishi (ganoderma or lingzhi), shiitake, maitake and cordyceps mushrooms.

How to get all the nutrients you need for your immune system

A diet rich in plant foods keeps your arteries clear so that the immune system cells could flow smoothly. Conversely, a diet rich in animal products are high in fat and can therefore clog the arteries, jeopardising the immune system.

In order to be effective and well absorbed by the body, nutrients must be obtained from wholesome plant foods.

Multivitamins that have been extracted and isolated from their wholesome food form and into vitamin pills make them a chemical or a drug. Such chemicals can have side effects. For example, beta carotene or vitamin A is an antioxidant found in carrots. A study in Finland showed that smokers who take beta carotene pills have more risk for lung cancer than smokers who don’t. But when you eat lots of carrots, you don’t experience such toxic side effects.

Studies show that eating nutritious foods and exercising more help to prevent at least 30% of cancers, 80% of heart disease, and 90% of diabetes.

The convenience of Nutritional Immunology food formulations

Eating about 30 different varieties of wholesome plant foods every single day helps ensure you get the nutrition that your immune system needs in order to function effectively and protect you from various illnesses.

However, the realities of modern life make it difficult for most of us to prepare all those plant foods every single day.

Thankfully, there is a really convenient and safe alternative to make eating all those plant foods every day really easy.

What are Nutritional Immunology food formulations and products?

Dr Jau-Fei Chen, PhD, the founder and pioneer behind the science of Nutritional Immunology, is an immunologist and microbiologist who has spent decades of research in Oncology and Immunology, studying different types of plants that can help our body build the best defense against life’s most common illnesses.

Through decades of hard work and dedication, her whole food formulations are now available to everyone in convenient powdered and liquid botanical beverages.

Every ingredient in every product goes through over 2,000 different tests to ensure that they are free of pesticides, harmful chemicals, and heavy metals, far surpassing any organic certification standards. Each ingredient is then prepared in the optimal processing method that would preserve the most nutrients. For example, soy must be heated to a specific temperature while most vegetables are not cooked.

All Nutritional Immunology products contain only carefully selected wholesome foods from specific species, specific parts of plants, and with synergistic combination. This clearly distinguishes them from any other product available in the market today.

Nutritional Immunology food products are NOT vitamins, supplements, herbal medicine, or even natural remedies. They are merely foods. Foods that provide the right nutrition, the fuel that our immune system really needs.

This convenience is so important in today’s fast-paced world, enabling us to eat a wide variety of highly nutritious plant foods every single day.

The Nutritional Immunology difference: What sets it apart

1. The Science

Nutritional Immunology products deliver optimal levels of the polysaccharides, antioxidants and phytochemicals found in wholesome plant foods.

They  are not isolated elements that support vitamin and mineral claims. And they are not synthetic, man-made vitamins or compounds that resemble those found in nature.

Nutritional Immunology products are effective because of the amount of research and professional expertise devoted to each product formulation:

  • Researching the different types of plant foods that contain the most phytochemicals, antioxidants and polysaccharides
  • Studying which plant species is most beneficial to the human immune system; for example, there are over 80 species of ginger but all contain varying amounts of nutrients
  • Analysing which parts of a plant — roots, seeds, berries, flowers — are the most nutritious
  • Selecting the most appropriate harvest time; for example, mushrooms must be harvested when still young to obtain optimum quality, while ginseng and cactus yield more nutritional values the older they are
  • Using appropriate processing techniques; for example, some plants must be heated before use while others should not be heated

2. The Process

Premium quality ingredients are grown and harvested in conditions that yield the highest levels of immune-supporting compounds. The ingredients are then prepared with only water and NO harsh chemicals. Freeze-drying is used to help preserve the energy stored as plant enzymes in all the ingredients.

All Nutritional Immunology products are formulated in-house (nothing is outsourced) based on the science of Nutritional Immunology.

The company owns and controls their own GMP-certified manufacturing facilities in USA and Singapore. The US facility also complies with FDA requirements.

Every single product is packed using state-of-the-art technology to ensure they are contaminant-free and that they retain all their nutrient content.

3. The Ingredients

All of the ingredients used in each product are wholesome foods that have been synergistically combined to yield maximum benefits for our immune system.

There are never any synthetic, artificial compounds or stimulants in the ingredients of Nutritional Immunology products.

Some of these foods are hard to come by in our typical diet, for example, cactus pads, cactus fruit, American and Asian Panax ginseng, Ji-Lin ginseng, ginseng berry, rose, a variety of mushrooms such as Cordyceps, ABM, maitake, shiitake, ganoderma or reishi, cassia seeds, ashitaba,, and kumazasa.

WHY NUTRITIONAL IMMUNOLOGY PRODUCTS? Nutritional Immunology formulations deliver optimal levels of the polysaccharides, antioxidants and phytochemicals found in specific parts and species of whole plant foods. They are NOT supplements made of isolated or synthetic vitamins and minerals that resemble those found in nature.

4. The Mission

Dr Jau-Fei Chen set out on a mission in 1987, over 30 years ago, to create a disease-free world through the science of Nutritional Immunology.

Every thing that her company has done stems from that one mission. Nutritional Immunology empowers you through education and convenience so that you can truly take control of your own health by knowing exactly how to eat, what to eat, and actually having these foods available to you very conveniently.

5. The Reputation

The quality and safety standards of Nutritional Immunology products are unmatched.

They are committed to continued research, studies, and sourcing only the best ingredients, using the best possible processing and packaging technology, so that you can very conveniently consume unique but extremely healthful plant foods every single day, regardless of how busy you are.


Every major organ system in your body relies on your immune system to defend it from viruses, bacteria, parasites, allergens, free radicals, DNA damage, insulin resistance, and the aftermath of inflammatory responses.

The better your immune system is at doing these jobs, the healthier you are. And the better you equip it with proper nutrition, the more effective it will be at doing its job.

Nutritional Immunology products support functions of vital body systems by balancing the immune system’s activity or energy in that system. If used properly along with other healthy lifestyle choices, each formulation brings balance to the body, resulting in reduced health risks and a better quality of life.

Taken according to the directions on the labels, the products are safe for all ages, should not cause harmful side effects and pose no risk of “accidental overdose” because their ingredients are whole foods.

Nutritional Immunology is a very complete science. It has discovered and is still discovering the various benefits of the plant world.

By keeping your immune system strong and in good balance, you are helping it to work more effectively to protect your health and the health of your loved ones.

In addition to good nutrition, exercise and deep breathing increase lymph circulation which in turn improves immune function.

Don’t let stress affect you. When you are stressed out, your body release corticosteroids, which suppress your immune system. Relax, and smile more.

Creating a life of excellence starts with your health. And you have the powers in your own hands to take control of your health.
