Immuron Protectyn 30c



Protectyn® is derived from colostrum which is the first milk from dairy cows that is naturally boosted with antibodies and other components to protect infants from diseases of the digestive system.

Protectyn® is scientifically formulated to be high in specific antibodies, namely anti-LPS antibodies, which target and remove harmful Bacteria and LPS (Lipopolysaccharide) Toxins.

These Bacteria and LPS Toxins have been associated with many diseases including:

  • Diabetes
  • Leaky gut syndrome
  • Bacterial translocation,
  • Irritable bowel syndrome,
  • Fatty liver
  • Metabolic syndrome.
  • Gut dysbiosis

What is Lipopolysaccharide (LPS)?

Lipopolysaccharide (LPS) are an ‘endotoxin’ found in the outer membrane of certain gut bacteria (including Gram-negative). Normally, LPS is contained within the gut lumen and does not cross the intestinal barrier. However, in cases of increased intestinal permeability, or leaky gut, LPS can pass through and enter the bloodstream.

Once in the bloodstream, LPS can trigger an immune response, leading to inflammation and tissue damage. LPS drives a range of health issues, including chronic inflammation, fatigue, depression, autoimmune diseases, and metabolic disorders.

LPS can contribute to the development of leaky gut by activating inflammation, disrupting tight junctions in the intestinal lining and increasing the passage of LPS and other toxins into the blood. Therefore, reducing LPS levels in the gut can be an important part of treating leaky gut and improving gut health.

How can Protectyn® colostrum help?

Colostrum is the first milk produced by mammals, including humans, in the first few days after giving birth. It is rich in bioactive compounds, including immunoglobulins and growth factors that support the newborns health and development. In adults, it can support immune function and gut health.

Colostrum has a unique ability to neutralize lipopolysaccharide (LPS). It contains antibodies, including immunoglobulin A (IgA), which can bind to and neutralize LPS in the gut, preventing them from crossing the gut barrier and entering the bloodstream.

Studies have shown that colostrum supplementation reduces LPS levels in the gut, leading to improved gut barrier function. Colostrum supplementation was found to significantly reduce LPS levels in patients with inflammatory bowel disease (IBD), which is characterized by chronic inflammation and damage to the intestinal lining.

Protectyn® is scientifically formulated to be high in specific antibodies, namely anti-LPS antibodies, which target and remove harmful Bacteria and LPS (Lipopolysaccharide) Toxins. 

Who should take Protectyn®?

Immuron Protectyn® is suitable for anyone with conditions associated with inflammation:

  • Diabetes
  • Leaky gut syndrome
  • Chronic fatigue syndrome
  • Irritable bowel syndrome,
  • Fatty liver
  • Metabolic syndrome.
  • Gut dysbiosis
  • Depression
  • Auto-immune conditions

Additional information


Protectyn® is a natural product derived from bovine colostrum enriched with anti-lipopolysaccharide (LPS) antibodies.

Each caplet contains:
Colostrum Powder – Bovine 200mg
Glucose 50mg
Lactose <20mg

Contains: milk proteins, glucose and lactose. Lactose has been reduced to < 10% via ultrafiltration. Gluten free.

Directions for use

Mild cases of Gut Dysbiosis: 2 tablet twice/day or 1 tablet 3 times per day
Severe cases: 2 tablets 3 times per day


Pregnant or lactating women and children should consult their healthcare practitioner prior to use. Protectyn® is not suitable for use in children under the age of 12 months due to containing milk proteins. Due to caplet size, Protectyn® is not recommended for children under six years of age unless under supervision of a healthcare professional. Consult your healthcare practitioner if symptoms persist.

Lactose intolerance: The amount of lactose in Protectyn® has been reduced <10% which equates to <20mg/caplet which is considered well below the level any clinical symptoms are expected to be caused in lactose intolerant patients.
Diabetics: The amount of glucose in Protectyn® is 50mg/caplet which equates to only 150mg glucose if three tablets/day are consumed.
