Infectious Threats Are Lurking Around Every Corner

ais-s02-a

The immune system is under constant attack from "foreign invaders."

Not just from viruses and bacteria in the air we breathe, but also from emotional stress, environmental toxins and more. Even certain foods are known to trigger an inflammatory response, or internal stress in the body.

Lack of sleep and a poor diet can also weaken the immune system, leaving the body more susceptible to infection.

If an infectious agent builds up in the body, the immune system can become overwhelmed… making it harder for the body to fight back.7

ais-s02-a

And the older we get, the more difficult it is to respond to immune challenges.8

ais-s02-b

Plus, the more stress in our lives9, and the more environmental toxins we're exposed to, the more battles the immune system has to fight…

The more the immune system has to fight, the greater the chance it can become overwhelmed, losing the battle to microorganisms all around us.

Your body's ability to combat viral and bacterial infections relies on nutrients from REAL whole food, powerful antioxidants and proper inflammatory response.

When your body doesn't have the support it needs, it's vulnerable to attack.

Weak immune support can lead to:

  • Higher risk of frequent infections & severe symptoms.
  • More frequent pneumonia, common cold and other infections.
  • Infections that keep coming back.
  • Infections that don't respond to medications.
  • Severe sickness from a common cold.
  • Sinus & lung infections.

The bottom line is… if your immune system is weak, it may mean you're more likely to get sick than other people. It's also more likely that there may be complications if you do get sick. An illness that is minor for other people could be more serious for you.

That's Why Taking a REAL Whole Food Vitamin Is the Best Support for a Strong Immune System

Unfortunately, Most People Still Think a Bottle of Vitamin C Is All You Need.

ais-s04a

You see, most Vitamin C is made from only ascorbic acid. Especially those brands that you find in the supermarket and big box stores.

Ascorbic acid is only one small part of vitamin C and it doesn't even exist in nature by itself.

Natural Whole Food Vitamin C used in premium supplements like Advanced Immune Support is Real Vitamin C.

Real Vitamin C includes a complex of ascorbic acid, broad-spectrum bioflavonoids and other nutrients the immune system needs to produce and regulate immune cells capable of identifying, containing, and neutralizing potentially harmful pathogens.1

Elderberry is another source of immunity support most people look for, but not all elderberry supplements are created equal.

Elderberry Concentrate is more potent and effective at reducing the duration and severity of cold and flu symptoms, according to multiple controlled human studies.10

And for the best, look for Elderberry made from concentrate that's also "farm-to-finish" with no extracts.

Farm-to-finish elderberries contain all available elderberry actives meaning it contains the active ingredients for maximum effect, unlike extracts.

But you won't get enough or the right kind of Real Vitamin C with bioflavonoids and "farm-to-finish" Elderberry Concentrate from a regular immunity vitamin.

ais-s04b

Finally, most store-bought supplements don't support both the innate immune system and the adaptive immune system for complete support when you need it the most.

Don't Settle for Anything Less Than…

The Body Needs Support for Both Functions of The Immune System

For protection from "foreign invaders", the body needs every part of the immune system to be strong.

As you may know, the immune system is actually made up of two systems: the innate immune system and the adaptive immune system.

ais-s06b

The innate immune system is the first line of defense the body has. It includes your skin, stomach acid, cough reflex and mucus, which traps bacteria and other small particles. However, it cannot distinguish between specific pathogens. It attacks any invader.

When the innate immune system fails to completely overcome a toxic or microbial threat, it hands off the fight to the adaptive immune system.

ais-s06a

The adaptive immune system takes a molecular "fingerprint" of the invader and attacks its weakness. By keeping copies of each pathogen or "fingerprint" in its memory, it gets stronger over time.

Adaptive immunity empowers "acquired immunity," which is the strongest protection the body can have against any invader.

Acquired immunity is so powerful that it can overcome reinfections even before symptoms appear.

ais-s06c

Advanced Immune Support contains clinically-studied ingredients proven to support both the innate immune system and the adaptive immune system.

This helps activate natural "Killer T-Cells," also known as NK cells. Killer T-Cells are a type of white blood cell with enzymes that can kill cells infected with a virus.11

What Makes Advanced Immune Support So Effective?

Advanced Immune Support contains clinically-studied ingredients proven to support both the innate immune system and the adaptive immune system.

It contains Whole Food Vitamin C. Which is REAL Vitamin C. That includes a complex of ascorbic acid, broad-spectrum bioflavonoids and other nutrients the immune system needs to produce and regulate immune cells capable of identifying, containing, and neutralizing potentially harmful pathogens.1

In addition to Elderberry, Zinc, Vitamin D3, Selenium, N-Acetyl Cysteine, 1,3-Beta-Glucan and more.

Plus to amplify the effects, Advanced Immune Support also contains Humic and Fulvic Extracts, to help optimize absorption of each and every ingredient in Advanced Immune Support.

Advanced Immune Support may simply be the best immunity support you can buy without a prescription.

Here's what's inside each and every powerful dose:

Advanced-Immune-Support-Front copy
ing-icon-01

Real Vitamin C & Antioxidant Support

Made from a broad-spectrum bioflavonoids, including quercetin, that works synergistically to help our bodies produce and regulate vital immune cells. Immune cells are capable of identifying, containing, and neutralizing potentially harmful pathogens.1

ing-icon-02

BerryShield® Elderberry Concentrate

Elderberry has an extensive history in helping to reduce the duration and severity of cold and flu symptoms. This non-GMO concentrate made from the Haschberg variety of "farm-to-finish" elderberries contains all available elderberry actives, unlike extracts, for a more potent and effective product. It is associated with reduced duration and severity of cold and flu symptoms according to multiple controlled human studies. 2

ing-icon-03

Vitamin D3 & Zinc

These two powerful nutrients are essential for immune health and function. They help boost the production of immune proteins, limit natural inflammatory responses from getting out of control, and may help slow the replication and mutation of viral infections.3, 12

ing-icon-04

Selenium

Selenium has been studied extensively for its effects on viral immune responses. Many studies are now suggesting that sufficient selenium intake may help slow the replication and mutation of certain viral infections.

ing-icon-05

Quercetin

Quercetin has powerful antioxidants and antiviral activity. It has shown an ability to help inhibit histamine release, decrease proinflammatory cytokines, and may help suppress IL-4 production.

ing-icon-06

N-Acetyl Cysteine (NAC)

This potent semi-essential amino acid is a powerful antioxidant and precursor to the "Master Antioxidant", glutathione. NAC is used to help ease symptoms of respiratory conditions by acting as an expectorant and improving glutathione activity in the lungs. Studies also show NAC to have a positive effect on lymphocyte immune cells.

ing-icon-07

Reishi Fruiting Body Extract

Reishi is frequently touted for its high 1,3-Beta-Glucan and 1,6-Beta-Glucan content. 1,3-Beta-Glucan is linked with increased activation of immune cells and total immunoglobulin production. Additionally, Reishi is recognized as an adaptogen due to its potential to support adrenal health and cortisol regulation.

ing-icon-08

Beta Glucan / BGF-Immune®

Beta Glucan helps stimulate both the innate and adaptive immune cells that detect and eliminate harmful bacteria and viruses. This clinically-studied for immune function ingredient is highly purified 1,3-Beta-Glucan, produced via a unique fermentation process to provide support for a healthy immune function by working on the cells of the innate immune defense system. Innate immune defense system responses and immune cell bindings are specific to 1,3 linkages unlike other sources of Beta-Glucan. 1,3 linkage cell receptor bindings can mobilize a complex set of immune defense mechanisms including targeted immune cell activation. And it's lower molecular weight means it's easily absorbed in the body for maximum benefit. 5

ing-icon-09

ResistAid® Larch Arabinogalactan

In a placebo-controlled, double-blind, randomized clinical trial, ResistAid® was shown to significantly reduce the occurrence of viral cold episodes and the duration of cold symptoms compared to a placebo. Additional experimental studies suggest larch arabinogalactan may increase the effectiveness of natural Killer T-Cells.13

ing-icon-10

Olive Leaf Extract

With a long history of use in the Mediterranean, Olive Leaf Extract helps support a healthy and balanced immune response. An 8-week study suggests olive leaf extract may positively alter white blood cell responses. Additionally, other studies have linked olive leaf extract with limited bacterial and viral replication.

ing-icon-11

Humic & Fulvic Extracts

These key ingredients not only have strong antibacterial and antiviral properties that may help reduce the severity and duration of infections. But they also help optimize nutrient absorption of every ingredient in Advanced Immune Support.6
