Clean Formula


Fast Fact

A study published in the journal of Clinical Immunology found that L-glutamine normalizes the effects of the TH2 immune response that stimulates inflammatory cytokines. The effects of L-glutamine in these studies show that it reduces intestinal inflammation and can help people recover from food sensitivities.

Fast Fact

The man famous for discovering the Krebs cycle Sir Hans Adolf Krebs — a German-born British biochemist who received (with Fritz Lipmann) the 1953 Nobel Prize for Physiology in the body was the first person to recommend taking L-glutamine for gut and immune health. Additional research supports this finding.

Fast Fact

Glutamine’s immune system support is closely related to its activity in our intestines. The amino acid helps maintain your intestinal lining, ensuring your body absorbs the nutrients it needs

Fast Fact

Glycine intake increases the reinforcement potential of the body’s connective tissues, which may conceivably impede the advance of invasive agents (viruses or bacteria), thereby enhancing the capability of the immune system to repel such invasive agents.

Fast Fact

Each stage of the body’s immune response relies on the presence of many micronutrients. Examples of nutrients that have been identified as critical for the growth and function of immune cells include vitamin C, vitamin D, zinc, selenium, iron, and protein (including the amino acid glutamine).

Fast Fact

Vitamin C supports epithelial barrier function against pathogens and promotes the oxidant scavenging activity of the skin, thereby potentially protecting against environmental oxidative stress.



Vitamin Premix

t-Cell Support

Teen Vitamin Premix (TVP) is a blend of 12 highly bioavailable vitamins, consisting of Vitamin A, D3, B1, B2, B3, B5, B6, B12, C, Folic Acid and Biotin. These vitamins are involved in key bodily functions like energy production, macronutrient metabolism, production of red blood cell and the maintenance of normal skin, vision and psychological function.


Vitamin D


Cytokine Support

At the cellular level, vitamin D exerts anti-inflammatory effects on immune cells that express the vitamin D receptor (VDR) such as monocytes, macrophages, and T lymphocytes, which in turn shapes the immune response during the onset of inflammation and infection and following vaccination.




Gut Barrier

Glutamine is the main fuel source for your body’s lymphocytes, white blood cells that fight infection and disease. But your blood’s glutamine levels decline when we’re sick or injured, reducing these immune cells’ ability to defend your body.

Glutamine is utilised at a high rate by cells of the immune system and is required to support optimal lymphocyte proliferation and production of cytokines by lymphocytes and macrophages. Macrophage-mediated phagocytosis is influenced by glutamine availability.

Gamma Amino Butyric Acid


GABA is a key calming neurotransmitter in the human nervous system that is also found in some foods. GABA acts to relax the nervous system by preventing overstimulation.

GABA has a number of effects on the immune cells such as activation or suppression of cytokine secretion, modification of cell proliferation and GABA can even affect migration of the cells. The immune cells encounter GABA when released by the immune cells themselves or when the immune cells enter the brain.


Vitamin C

Vitamin C

need copy

Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system.

Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system.

Vitamin C supports epithelial barrier function against pathogens and promotes the oxidant scavenging activity of the skin, thereby potentially protecting against environmental oxidative stress. Vitamin C accumulates in phagocytic cells, such as neutrophils, and can enhance chemotaxis, phagocytosis, generation of reactive oxygen species, and ultimately microbial killing.


Fibersol -2

Maize Fiber


Prebiotics like Fibersol-2 are also a vital source of ‘food’ for the gut bacteria. This helps them to produce beneficial substances like short-chain fatty acids, which strengthen the physical gut barrier and regulate the immune response.

A healthy gut also ensures that nutrients are properly absorbed.



Magnesium Chelate

Cramp Support

Magnesium (Mg) serves as a co-factor in more than 300 enzymatic reactions, including energy production. Magnesium improves the white blood cells’ ability to seek out and destroy germs. Low magnesium can lead to a cytokine storm, during which the body attacks its own cells and tissues instead of fighting off infection. This creates inflammation, cell and tissue damage, narrowed blood vessels, and blood clots



Zinc Chelate

Cortisol Support

Studies show that zinc is important in almost all aspects of the immune system: It helps skin cells and cells lining our organs prevent pathogens from entering, and it keeps the thymus and bone marrow, which are responsible for generating immune cells, functioning normally.




Barrier Repair

Glycine helps to rebuild the tissue that lines the digestive tract, keeping food particles and bacteria inside the gut where they belong, rather than allowing tiny openings to form that pass particles to the bloodstream where they trigger inflammation.



Selenium Chelate


Selenium is an essential micronutrient. It is a structural component of the amino acid selenocysteine that is incorporated into 25 selenoproteins. Glutathione peroxidase and thioredoxin reductases (TrxRs) are examples of selenoproteins with antioxidant features. These proteins interfere with oxidative stress and thereby play an important role in the regulation of the immune system and inflammatory processes.

  1. Janine K (verified owner)

    The taste is like freshly squeezed orange juice. Absolute yum! My teens (and the whole family) love it!

  2. Shannon Ambrose

    Great tasting and filled with all the goodness needed especially when no matter how hard you try it’s difficult to get a busy teen focused on healthy eating!

  3. Makgorong (verified owner)

    Iv’e noticed a difference in my kids energy levels and just general well-being. Am very happy!

  4. Jo-Anne (verified owner)

    My daughter gets sick very easily and battles with tummy aches and headaches. Since starting on Immunergy, she is having all symptoms a lot less and overall a much healthier teen.

  5. Carla (verified owner)

    My son suffers with sinus and bloating. This is not why we took this to begin with. The purpose was to keep his immune system up whilst writing matric finals. It has gut health vitamins and we have definitely noticed a difference and suddenly his sinuses seem to be doing a great deal better too.

  6. Madlene Matthews (verified owner)

    Since giving my daughter the Immunergy “orange juice” since Sept 2023, she has not had any cold/flu infections at all !!
    And she was so prone to catching the germs so easily, she was constantly sick since the start of 2023, until she started taking Immunergy.
    Soooo glad I found this AMAZING product !!!

  7. Madlene Matthews (verified owner)

    Absolutely fantastic product!! My daughter’s immune system is so much better already!

  8. Zaiden Moses (verified owner)

    Great product for the family this winter! 10/10 reccomend for those who are prone to getting sick. Well Done Bioteen!!!

  9. Zaiden Moses (verified owner)

    The product arrived sooner than I expected which is great! I have been taking it for the last 2 weeks now and I notice a slight change, which is a good sign. I usually get sick quite often, so I am hoping this would help, especially during winter. The orange flavor is amazing too, thanks Bioteen for the amazing freebies!!

Bioteen’s Immunergy has been specially developed to target multiple immune supporting pathways using the right amount of trademarked, high quality functional ingredients, like Fibersol®-2  as well as a complement of other beneficial nutrients.


Let’s see how all the ingredients work together to keep you healthy:


Reinforcing physical barriers

Physical barriers are the most basic form of defense that your body has against harmful pathogens. If the pathogens can’t gain entry to your body, it can’t infect you. These physical barriers are made up of your skin and various mucous membranes, like those in your nose, mouth, lungs and urinary and gut lining (1-4) .


Bioteen’s Immunergy contains a number of nutrients including L-glutamine, vitamin C and vitamin D which work directly and indirectly towards reinforcing these barriers through maintaining their structural integrity.


Supporting immunity at gut level

There is a huge population of bacteria that live in your gut, known as your microbiome. Some of them are good while others are bad. It’s important to support the growth of the good bacteria to ensure adequate production of metabolites like short chain fatty acids (SCFAs). SCFAs have the ability to strengthen the physical gut lining and also help the microbiome communicate with the gut associated lymphoid tissue (or GALT) to mount an appropriate immune response. When there is an imbalance between the good and bad bacteria (which is known as dysbiosis) then SCFA production is also disrupted which can have a negative effect on your immunity and general health (5).


One way to do this is to include prebiotics in your diet. Prebiotics (like the ones found in Fibersol®-2, one of the core ingredients in Bioteen’s Immunergy) are food for your good gut bacteria. When your good gut bacteria are well fed, they are able to grow and multiply, keeping your gut health in check. 


Train innate immune cells and support immune cell health 

If a pathogen is able to breach your physical barriers, you need your innate immune system to step in and neutralise the threat before it can get too far.


Bioteen’s Immunergy contains a complement of beneficial nutrients that have been shown to support immune cell proliferation, differentiation, development and maturation. Having healthy immune cells is important because if they are damaged, they can respond to invading pathogens and protect you. 


Supporting the stress-immune axis

Stress causes your body to produce higher levels of the stress hormone cortisol. In small amounts, cortisol is helpful and can even give your immune system a boost by limiting inflammation. But, if this stress continues for too long or becomes chronic, then it has the opposite effect and can suppress your immune system, predisposing you to an increased risk of infections (6,7).


Bioteen’s Immunergy contains stress busting nutrients like GABA to support your stress-immune axis. Less stress equals a stronger immune system.
