It was designed by a leading and published nutraceutical research scientists to boost immunity in 7 key ways, systematically.
Just a small dropper full a day can support immunity.
Let’s look at how each ingredient works to support your immunity:
Bupleurum Root (Chaihu)

Bupleurum is a member of the Apiaceae family of plants and has been a staple of Traditional Chinese Medicine (TCM) for over 2,000 years. It is referred to as "Chai Hu" in TCM texts.
Studies show:
Bupleurum Root (Chaihu) alleviates a wide spectrum of disorders in a multi-target manner through its immunomodulatory (immune-stimulating), hepatoprotective (liver supporting), and effects.
In a human study Bupleurum Root (Chaihu) reportedly supports the bodies natural defenses in influenza, the common cold, malaria, and pneumonia, with the majority of patients.
Studies show that it has antioxidant and protective abilities, which can help with the normal inflammatory process associated with challenges (inflammation can be more dangerous!)
Bupleurum has a stimulating activity that helps the body to process steroids that is beneficial in strengthening the immune system.
Elderberry Fruit

Elderberry is the dark purple berry from the European elder tree. It has long been used and studied for its ability to positively impact symptoms related to seasonal immune challenges.
One study showed that elderberry interacts the early by blocking key viral proteins responsible for both the attachment and entry into the host cells.
Another study showed a significant reduction of normal symptoms duration and severity in air travelers.
Research found compounds in black elderberry (Sambucus nigra) could directly impact cellular entry and subsequent replication, in part attributed to the anthocyanidin responsible for the vivid purple coloring of the fruit.
Several studies have demonstrated that elder extract is highly effective in mitigating flu-like symptoms—specifically, the flavonoids in the elderberry extract binding.
Echinacea Herb

Echinacea is the name of a group of flowering plants in the daisy family. Studies have linked echinacea to benefits like supporting a normal inflammatory response, a healthy immune response, and desired blood sugar levels .
Studies on Echinacea extracts have shown that some of them, but not all, possess multiple beneficial actions in the maintenance of normal of respiratory function.
Echinacea seems to activate chemicals in the body that interact with inflammatory responses, which might improve symptoms.
Because of its immune-supporting and normal inflammatory effects, echinacea can be used to support upper respiratory systems. In fact, in clinical studies it support the structure function benefits of the pulmonary system in those study participants.
Astragalus Root

Astragalus is an herb that has been used in traditional Chinese medicine for centuries. It has many researched health benefits, including immune-supporting, healthy aging, and normal inflammatory effects.
One study showed astragalus root may help reinforce immunity in animals with challenges.
Astragalus root extract may alter the function of the immune response mediators and cell migration via HPA in macrophages.
Astragalus membranaceus, a traditional Chinese herb, has been used to reinforce pulmonary airways.
Licorice Root

Licorice refers to the root of a plant called Glycyrrhiza glabra. It has been used therapeutically since Egyptian times, and its active compound, glycyrrhizin, has been studied for its role in aiding digestion and immunity.
Recent studies have shown that licorice root metabolites possess many pharmacological activities like immune-support, cellular adaptation, and other activities.
Glycyrrhizin has strong immune-supporting and healthy-inflammatory properties.
Licorice may support normal respiratory health.
Ascorbic Acid

Ascorbic acid is a form of vitamin C involved in the repair of tissue and the enzymatic production of certain neurotransmitters; enzymes use it to support immunity..
Ascorbic acid, due to its effects and diversity of regulated pathways, can support immunity.
Ascorbic acid is essential for effective immune system function and, further, it can be a potent immune system vitamin when high glycemic dietary carbohydrates are restricted.
Ascorbic Acid is essential to reinforce the immune system by increasing adding value to the protective systems of the organism.
Zinc Sulfate

Zinc sulfate is a natural form of the mineral that can help reverse deficiency. Zinc is essential for immunity, and over 2 billion people don’t get enough daily zinc.
Zinc also is an antioxidant and has healthy-inflammatory actions that can help boost immunity and reduce the effects of infection.
Zinc plays a critical role in virtually all aspects of the immune system. Zinc is needed for the optimal function of the many different types of white blood cells that protect the body from illness and infection, in addition to cytokine production, phagocytosis, and other immune system processes. Even mild zinc deficiency can weaken the immune system.
Zinc has been studied as a way to reduce the duration of a common challenges. Some studies have found that zinc lozenges may reduce the duration of difficult symptoms and may assist normal upper respiratory function during times of stress.
This Cochrane review provides convincing evidence from 13 randomized placebo-controlled trials regarding zinc’s potential role in immune support and function..
Researchers have also discovered that zinc may have other immune-health properties that help your body have a strong first response at the on set of symptoms.
