LeucoGUARD® is a patented shark liver oil extract, specially processed from the livers of deep, cold water sharks. It is rich in compounds called Alkylglycerols.
Alkylglycerols are found in high concentrations in mother’s breast milk, the liver, spleen and bone marrow, all of which play an important role in immunity.
Alkylglycerols are active substances that give breast fed babies crucial protection against infections until their own immune systems are fully developed. As a natural supplement, Alkylglycerols can be found in LeucoGUARD® shark liver oil.
In 1952 Dr Astrid Brohult, a Swedish scientist carried out much research on Alkylglycerols which he sourced from calf bone marrow. Shark liver oil was subsequently found to be a richer source of the same compounds.
Further research showed that the addition of a methyl group to the Alkylglycerol molecule, known as methoxy-substituted-Alkylglycerols, increased their effectiveness in the body. There are over 45 citations on Alkylglcerols dating back to 1963. See below
Sharks are amazing creatures and have been studied by scientists for many years. They appear to be incredibly resistant to infection and sick or malignant sharks have virtually never been found. They also play a crucial role in maintaining the health of the world’s marine ecosystems. Recent practices such as shark finning and the cosmetic trade have caused a massive decline in the worlds shark populations, especially in the tropical oceans of the world.
LeucoGUARD® is produced from species of dogfish, Squaliformes, which are a by-product of marine fisheries in the North East Atlantic. These are not endangered species and we do not fish them specifically for this oil. We are currently seeking the seal of sustainability for the sharks we use. This is in line with our company’s dedication to sustainability and marine conservation in all aspects of our business.
Squalene is a type of unrefined shark liver oil you will find on sale. Its origin is often from highly endangered species of sharks and it does not contain the methoxysubstituted-Alkylglycerols in LeucoGUARD® which research has shown are the ones most effective. Furthermore, LeucoGUARD® is produced through a molecular distillation process which removes impurities.
Shark cartilage on the other hand was once thought to be responsible for the sharks incredibly immunity but research has proven that this comes from the Alkylglycerols in the sharks liver oil.
