▸Key Takeaways
- Supports balanced immune function, not overstimulation
- Delivers standardized alkylglycerols from shark liver oil
- Supports cellular communication and membrane health
- Helps the body respond to stress and oxidative damage
- Purified for safety, consistency, and quality
Shark liver oil has a long history of traditional use by Scandinavian fishermen, who relied on the golden oil to support immune resilience in the face of frigid waters, fierce storms, and brutal Nordic winters. In 1922, two Japanese doctors — Dr. Tsujimoto and Dr. Toyama — unlocked the secret to shark liver oil’s efficacy: alkylglycerols.
Decades of research suggest that alkylglycerols may help modulate immune function while supporting cellular health and the body’s natural detoxification processes. Immun-ALK captures the power of these compounds using sustainably sourced shark liver oil that is carefully purified to remove heavy metals, pesticides, and other contaminants.
What Are Alkylglycerols?
Alkylglycerols are bioactive lipids that play a role in immune cell function and communication. They belong to a class of fats known as ether lipids and are naturally found in human bone marrow, liver, spleen, and breast milk.
Their unique structure makes them more stable than many other fats, allowing them to persist in tissues that are constantly renewing, such as blood cells. This stability also allows them to integrate into cell membranes, where they may influence how cells function and communicate.
Shark liver oil is one of the richest natural sources of alkylglycerols, though they are also found in smaller amounts in certain marine species such as stingrays and chimera.
Why Choose Immune-ALK?
- Standardized potency: Provides a consistent 100 mg of alkylglycerols per softgel
- Purified for safety: Removes heavy metals, pesticides, cholesterol, and excess fat-soluble vitamins
- Sustainably sourced: Derived from non-endangered species and repurposed marine resources

The Science Behind Immun-ALK
Immune System Balance
The immune system is your body’s natural defense against internal and external challenges. Research suggests that alkylglycerols help support the activity of immune cells such as macrophages and neutrophils, which play a key role in maintaining healthy immune function.
Importantly, Immun-ALK is not an immune stimulant, it supports immune modulation, helping the body maintain a balanced response rather than pushing it in one direction.
Cellular Function & Communication
Healthy cells depend on flexible, responsive membranes to regulate what enters and exits. Research suggests that alkylglycerols may support cell membrane flexibility, which can help optimize nutrient exchange and cellular resilience.
Cells also rely on signaling systems to coordinate responses throughout the body. By integrating into cell membranes, alkylglycerols may help support efficient cell-to-cell communication, allowing the body to adapt more effectively to stressors.
Stress Response & Cellular Protection
Oxidative stress occurs when free radicals outpace the body’s antioxidant defenses, potentially impacting cellular function over time. Research indicates that alkylglycerols may help support antioxidant activity, contributing to the protection of cells and tissues from oxidative damage.
Preclinical research also suggests that alkylglycerols may support healthy adrenal function, helping the body adapt to physical stress and maintain resilience under demanding conditions.
Support for Natural Detoxification
Every day, the body works to process and eliminate environmental toxins. Preliminary and unpublished data suggest that alkylglycerols may support the body’s natural detoxification processes, including the handling of heavy metals such as mercury.
Who Should Consider Immun-ALK?
Immun-ALK may be a valuable addition for individuals looking to support immune balance and overall resilience, including:
- Those experiencing chronic stress or fatigue
- Individuals seeking balanced immune support rather than stimulation
- People exposed to environmental stressors or pollutants
- Aging individuals looking to support immune and cellular health
A Smarter Approach to Immune Support
Immune health isn’t about pushing the system harder — it’s about helping it function more efficiently. By supporting immune modulation, cellular communication, and stress resilience, Immun-ALK offers a more targeted approach to long-term wellness.
If your goal is to support your immune system with precision, not just stimulation, Immun-ALK provides a research-backed solution rooted in the unique benefits of alkylglycerols.
