Immunity - Enhance your Body's Natural Defenses

With over 70% of one’s immune system found within the gastrointestinal tract, your gut health is a critical part of your immune health. Combine Immunity with the rest of Silver Fern's gut focused supplements to maximize your body's immune defenses. It's time to take control of your immune system and set yourself up to aggressively fight back against sickness and eliminate the things that make you sick!
- Bolsters the immune system to fight off harmful viruses, pathogens, toxins, and molds
- Destroys or eliminates pathogens that are harmful to the immune system
- Creates beneficial natural antibiotics to selectively kill bad bacteria while supporting the good bacteria
- Reduces the duration and severity of sicknesses
- Reduces common allergy symptoms (runny nose, cough, sneezing, itchy eyes, etc.)
- Weakens the impact of viruses
Immunity Ingredients

Bacillius Subtilis HU58
Bacillus subtilis has been extensively studied on a genetic and functional level for its ability to produce targeted antibiotics and modulate the immune system. Bacillus subtilis can produce 12 strong antibiotics that arepotent fighters of opportunistic and harmful bacteria. This allows for effective reconditioning of the gut microbiome without the decimating effects of broadspectrum antibiotics. Additionally, Bacillus subtilis can improve the body’s natural defenses by producing antimicrobial compounds, cytokines, and immunoglobulins.
Quercetin
Quercetin belongs to a class of nutrients known as flavonoids. This potent antioxidant has antiviral properties and provides immune support in a number of ways. It can increasing neutrophil chemotaxis and respiratory-burst activity, macrophage phagocytosis, NK cell lytic activity, and lymphocyte proliferation. These mechanisms block the replication of viruses and inhibit their ability to attach to human host cells.
EpiCor® Yeast Fermentate
EpiCor® is a natural, whole food supplement derived from baker’s yeast which is then fermented and deprived of oxygen.
- Significantly increases sIgA and reduces IgE
- Significantly reduces duration and incidence of cold and flu
- Significantly reduces allergy symptoms
- Increases serum antioxidant protection and natural killer cell activity in just 2 hours
- Reduces inflammatory response to histamine-induced skin inflammation, suggesting that similar effects may happen across mucosal membranes after consumption
- Improves constipation and GI discomfort
Ginseng
Ginseng is one of the most beloved herbs used in traditional Chinese medicine. This slow growing root enhances our resistance to microbial and viral attacks. Ginseng elicits a wide range of activities from the immune system including cytokine modulation, promoting NK cell and macrophage production, stimulating dendritic cells, and more.
Immulink Mushroom (MBG®)
Immulink MBG® is a bioactive polysaccharide derived from the cell walls of medical mushrooms known as Ganoderma lucidum (or Reishi mushrooms). Immulink MBG® can help modulate the immune system and also acts as a novel source of prebiotics, which can feed beneficial keystone bacteria. It also helps maintain immunity during times of high stress and long, labor intensive workdays, both common causes of increased illness frequency and severity.
