The proper functioning of the body depends on the cells' ability to adapt to daily stressors—whether environmental, dietary, or physiological. Supporting the body’s natural protection and renewal mechanisms is key to maintaining this balance.
Alkylglycerols are specific fatty acids naturally present in small amounts in certain human tissues, notably the bone marrow, liver, and spleen.
The bone marrow plays a central role in the immune system, serving as the primary site for the production of immune cells (white blood cells such as B lymphocytes, macrophages, etc.) and hematopoietic stem cells that give rise to all blood cells, including immune cells.
The spleen, a secondary lymphoid organ, filters the blood, removes pathogens, and contributes to the production and maturation of immune cells, particularly lymphocytes.
The liver supports immunity indirectly by producing complement proteins (circulating immune proteins) and hosting specific immune cells like Kupffer cells (hepatic macrophages).
Alkylglycerols are also naturally found in shark liver oil, which is a concentrated source.
These lipid compounds help form cell membranes and support cellular structure, facilitating the exchange of substances between the cell and its environment, while contributing to membrane integrity and proper cell function.
Shark liver oil has been traditionally used in certain regions to supplement the diet with specific fatty acids due to their potential health benefits.

What Does Science Say?
The alkylglycerols in PHYSIOMANCE® ALKYL have been the subject of numerous scientific studies highlighting their potential roles in supporting immunity, reducing inflammation, and providing antioxidant benefits.
However, under current European regulations, no health claims have been authorized for these compounds. While no specific benefit is officially recognized, this bioactive ingredient is drawing increasing scientific interest and opens promising avenues for exploration.
Key Benefits of PHYSIOMANCE® ALKYL

Highly Concentrated Shark Liver Oil
Shark liver oil is primarily extracted from the livers of cold-water, deep-sea sharks such as Greenland sharks (Somniosus microcephalus) and other northern species. These fish are adapted to extreme conditions and have large livers rich in specific fatty acids, particularly alkylglycerols.
Traditionally used for centuries in Nordic and Scandinavian countries, shark liver oil was consumed during harsh winters when food was scarce, to support general vitality. This empirical, natural approach to health was passed down through generations—long before modern research confirmed the properties of its bioactive components. Today, shark liver oil is recognized for its high natural content of alkylglycerols—fatty acids also found in human bone marrow, spleen, and liver.
Eco-Responsible Fishing
The shark liver oil in PHYSIOMANCE® ALKYL comes from eco-responsible fishing practices that comply with the strictest international marine sustainability standards. The supply chain is carefully regulated to preserve marine ecosystems and biodiversity, avoiding overfishing and ensuring that no endangered species are used. Capture methods are selected to minimize environmental impact and ensure full traceability.
