Doctor Reveals Little-Known Immune Health Secret

Critical News for Anyone 40 or Older


If you’ve reached the age of 40, 50, or more, you’ve certainly noticed your body changing.

Some of these age-related changes are obvious. More gray hairs seem to pop up daily . . . muscles start to lose some of their tone . . . and of course, wrinkles develop in once-taut skin.

Our culture is obsessed with keeping these changes at bay. We spend billions of dollars annually on face lifts, wrinkle creams, hair dye, and other anti-aging measures.

Unfortunately, as noted holistic medical physician Dr. David Brownstein warns, these changes are not the ones we should be most concerned with. After all, a wrinkle-free face and tight skin will do nothing significant to help you enjoy a long, healthy, happy life.

On the other hand, a different age-related change has a major impact on your quality of life as you grow older. And while you’ve probably never even heard about it, Dr. Brownstein encourages anyone 40 or over to give it serious consideration — starting today.

So what is this change that takes place as you grow older?

Well, it has to do with your immune system. And while this information may not sound sexy, trendy, or exciting, you should know that the aging process alters immune function substantially. So substantially, in fact, medical researchers have now given these age-related changes a distinctive name: immunosenescence.

You’ll have a better understanding of what this terms means shortly. But first things first.

Dr. Brownstein has seen that most of his patients do not even really understand where their immune system is located . . .

Your Immune System Extends Throughout Your Body

Your immune system is not just one “thing.” It is an entire network of cells, tissues, and organs that work together to protect you from potential hazards.

Your bone marrow, your thymus gland, your lymphatic system, skin, gut, spleen, and other areas are all involved in your immune-system function.

Two main components of immune function are intimately interconnected. These components work together to give you around-the-clock surveillance and defense.

Your first-line immune defense is called the innate immune system. Your skin, which provides a mechanical barrier to antibodies, is part of this innate system. Other examples of innate immune first-line defenders are the mucus and cilia lining your respiratory tract, as well as the saliva in your mouth and pH in your digestive tract. All of these mechanical and chemical defenses are part of your innate immune system and they work to protect your body from potential threats to your health.

The innate system also contains several types of immune cells, many of which are white blood cells. For example, neutrophils are a specific type of white blood cell, and the most numerous innate immune cells in your bloodstream. They are able to engulf and ingest invading organisms.

The second component of immunity is your adaptive immune system. Its weapons include antibodies against specific organisms, as well as a specific group of immune cells.

Adaptive immunity relies heavily on another type of white blood cell called a lymphocyte. These cells come in different forms. B lymphocytes are involved in antibody responses. During these responses, B cells secrete antibodies, which circulate in the bloodstream and other body fluids. These antibodies bind specifically to the foreign antigens that stimulated their production. This binding process functions to inactivate and neutralize pathogens.

Cell-mediated immune responses are the second class of adaptive immune response. In cell-mediated responses, activated T lymphocytes react directly against foreign antigens to either destroy them directly or signal other cells from the innate system for help.

Immune memory is a central feature of the adaptive immune response. When B or T cells become activated, they multiply rapidly. When the immune issue becomes resolved, these cells stop dividing but are retained in the body as memory cells. If the same pathogen enters the body again, a memory cell is set to react and remove the pathogen before it becomes established.

And here’s where age comes into the picture . . .

Aging Has a Huge Impact on Immune System Function

The term immunosenescence means that, with advancing age, some of your crucial immune system functions become altered.

Immunity relies heavily on T cells, which are produced primarily in the thymus gland located in your chest.

Your immune system contains two types of T cells. Naïve or “virgin” T cells, which are abundant early in life, respond initially to potential health concerns. However, once these cells respond to a specific threat, they convert to memory T cells. These memory cells are programmed to remember and respond to threats that recur.

Think about school teachers, hospital nurses, and pediatricians — these individuals come into direct contact with hundreds of immune‑system threats every day. Ideally, their T cells would encounter these immune‑system threats and the memory cells would then be programmed to remember and respond to those hazards whenever they occur in the future. Unfortunately, years of relying heavily on the body’s adaptive immune system can take a toll on these cells.

With aging, your thymus gland shrinks and the supply of naïve T cells can become depleted, making the immune response less vigorous. Additionally, worn‑out memory T cells begin to accumulate in excessive numbers, which leads to an imbalanced inflammatory response.

Immunosenescence also involves other changes. Your bone marrow contains stem cells that develop into a variety of immune‑related cells. With advancing age, bone marrow may become less able to produce these stem cells. Some of these are precursors to cells involved with your innate immune system, while other stem cells give rise to adaptive immune cells.

With aging there is often a decrease in the number of T helper cells and a decrease in what are called natural killer or NK cells. These NK cells are important in immune regulation. They help to eliminate used up or senescent immune cells that secrete pro‑inflammatory chemicals.

Are you starting to see why it’s so important to maintain optimal immune function as you grow older?

These 4 Factors Also Impact Your Immune Function

Of course, the aging process is not the only reason for sub-optimal immune function. You should also be aware of these four additional factors that could potentially affect healthy immune-system function.

How to Support Your Immune System

Factor #1: Chronic, long-term stress can upset the balance of immune inflammatory responses. That’s why it’s important to maintain healthy relationships and avoid social isolation, decrease stress levels, and seek appropriate help for any life-impacting emotional issues. If you are feeling overwhelmed and run-down, chances are your immune system is feeling it too.

Factor #2: Poor quality sleep also affects immune health and inflammatory balance. Good sleep enhances the formation of immunological memory, which in turn enhances adaptive immune response. Most experts recommend seven to nine hours per night of high-quality sleep for adults.

Factor #3: Too little exercise and unhealthy weight gain can also affect your immune system. The immune system cells need to co-exist in a certain balance for good health to be maintained. Many factors, including diet and excess body fat, can tip this balance, creating immune cells that can harm, rather than protect, our bodies. Excess body fat, particularly abdominal fat, triggers the production of so-called “pro-inflammatory” immune cells, which circulate in the blood and promote inflammation in our bodies. Maintaining an optimal weight with diet and exercise can help support healthy immune function.

Factor #4: Dietary factors play a critical role in immune health. It’s important to eat plenty of phytonutrient- and antioxidant-rich foods, including dark leafy greens, tomatoes, peppers, broccoli, berries, and other colorful fruits. Unfortunately, Dr. Brownstein has found that many of his patients — even those over 40 or 50 — eat far too many fast or packaged foods and far too few fruits and vegetables. That led him to look for a practical solution to help support immune health.

Targeted Nutrients Promote Healthy Immune Function

Because of the effects of aging, stress, and dietary factors on immune function, Dr. Brownstein began to look for specific nutrients that support the healthy functioning of this vital body system. Almost immediately, one nutrient came up again and again during his research.

Wellmune® With Beta Glucans

Dr. Brownstein was excited to learn about the natural ingredient Wellmune, an advanced nutritional product shown in clinical studies to safely boost key immune responses that help keep your body healthy1.

Wellmune is a natural and unique beta glucan derived from a proprietary strain of yeast. It strengthens the body’s natural defenses by activating key immune cells — without over-stimulating your immune system. This in turn supports overall health and well-being.

In addition, Wellmune helps mobilize the natural response of immune cells to maintain energy and focus, and helps protect against the harmful effects of stress.

Once swallowed, immune cells in the GI tract take up Wellmune and transport it to immune organs throughout the body. While in the immune organs, immune cells called macrophages digest Wellmune into smaller fragments that are slowly released over time. These fragments bind to neutrophils, the most abundant immune cells in the body. In fact, neutrophils account for up to 60% of all immune cells.

By strengthening the function of key immune cells, Wellmune is a safe and effective natural solution for those concerned about healthy aging.

For your peace of mind, Wellmune is patented, Generally Recognized As Safe (GRAS) under U.S. FDA regulations, non-allergenic, and GMO-free.

And as good as Wellmune is for your immune system, Dr. Brownstein didn’t stop there . . .

After extensively researching nutrients with beneficial effects on immune function, he decided to formulate an immune health “multi-tasker.”

With that goal in mind, he created RETAMIN®. This advanced all-natural dietary supplement contains Wellmune and eight additional ingredients specifically chosen to help strengthen immune cells and promote immune system balance as well as overall health.

Retamin supplemental facts

So in RETAMIN, in addition to Wellmune, you’ll also find:

Maitake Mushroom — Another Source of Immune-Supporting Beta Glucans

Beta glucans are naturally occurring polysaccharides which are not produced by the body. The only way to get them is through outside sources, which include nutrients such as Wellmune and maitake mushrooms.

Researchers have been looking at beta glucans for over a century because of their ability to promote immune-system function. As immunomodulators2, they increase host immune defense by activating the complement system, enhancing the function of macrophages and natural killer cells.

Maitake is known in Japan as the “dancing mushroom.” With its beta glucan properties, maitake has been widely researched for its effects on the immune system, activating a host defense response by stimulating the proliferation of certain immune cells.

Zinc — a Trace Element Critical to Immune Function

Researchers believe that zinc helps play a role in maintaining healthy thymus function in aging individuals3. As you’ve already heard, the thymus is important in the health of your adaptive immune system, as it is vital to the development and maturation of T cells. Zinc serves as a molecular signal for immune cells and works as an antioxidant to decrease oxidative stress and balance the inflammatory response4.

Unfortunately, older adults frequently don’t consume enough of this nutrient. One study reported that those aged 60-65 years old had intakes below 50% of the recommended daily allowance of zinc5.

Immune Health Superstars — the Antioxidant Vitamins A, C, and E

RETAMIN contains three antioxidant superstar vitamins: vitamin A, vitamin C, and vitamin E.

Vitamin A is an antioxidant vitamin that plays a role in both innate and adaptive immunity6. It functions in the development of certain immune cells, including T helper cells and B cells. It also functions in antibody response to specific antigens and helps maintain the structural integrity of mucosal immune barriers.

Vitamin C (ascorbic acid), another antioxidant vitamin, plays a key role in the immune system and the antioxidant defense system7. It helps reduce DNA damage in immune cells and stimulates the production and function of immune cells such as neutrophils and lymphocytes. Animal studies indicate that supplemental vitamin C increases antibody production and balances the release of inflammatory chemicals.

Vitamin E is also a powerful antioxidant. Vitamin E helps protect cell membranes of immune cells, and enhances lymphocyte function8. It helps to maintain a balanced inflammatory response and works to scavenge free radicals. Studies indicate that very few people in the U.S. meet the requirements for vitamin E from food intake alone.

Vitamin D — the Hormone-Like Vitamin

Most people know that Vitamin D is absolutely essential for optimal health, but they may not be aware that Vitamin D is actually a hormone, because it must be synthesized before it can be used by the body. Vitamin D is obtained through sun exposure and then activated by the liver and kidneys. Because of its unique properties Vitamin D is needed for many of the body’s internal processes, and is particularly important to immune health.

According to the National Institutes of Health, older adults are at increased risk of developing vitamin D insufficiency. That’s because with aging, skin cannot synthesize vitamin D as efficiently. Plus, older individuals are likely to spend more time indoors, and they may have inadequate intakes of the vitamin9.

RETAMIN contains vitamin D, which stimulates immune cell proliferation and modulates both the innate and adaptive parts of the immune system10. Vitamin D affects the ability of B and T cells to “communicate” with each other in order to regulate the level of immune system activation.

Astragalus — the Traditional Chinese Herb

RETAMIN also contains the herb astragalus, which has been used in traditional Chinese medicine for thousands of years. Astragalus is considered an adaptogen, meaning it helps protect the body against various stresses — physical, mental, and emotional.

Astragalus also displays antioxidant properties. Emerging research suggests that astragalus helps protect, support, and gently stimulate the immune system.

Olive Leaf Extract From the Biblical Tree of Life

In the Bible, the olive tree is known as the “tree of life.” I’m sure you’ve heard of the heart-healthy Mediterranean diet, which includes olives and olive oil.

However, a unique molecule known as oleuropein — a potent polyphenol antioxidant — has been isolated from the leaf of the olive tree. Olive leaf extract inhibits DNA damage from oxidative stress, and this helps with inflammatory balance necessary for optimal immune function.

As you can see, RETAMIN is not a simple one-ingredient nutrient. Dr. Brownstein has created a comprehensive formula that covers the bases when it comes to keeping your immune system happy.

Of course, Dr. Brownstein takes RETAMIN himself on a daily basis. He understands how important it is to maintain a healthy immune system — especially with his busy family life, medical practice, and active lifestyle.

But you don’t have to take his word for it . . .
