Shark Liver Oil contains alkylglycerols (AKGs) and squalene, compounds traditionally used to support immune defense and tissue healing. Naturally rich in vitamins A and D, it helps strengthen mucosal barriers and promote the body’s natural healing processes.*
The immune system relies on balanced signaling and healthy cells to function properly. Alkylglycerols, found naturally in shark liver oil and human breast milk, help support normal immune cell activity and resilience during periods of increased physical or environmental stress. Deep Defense is designed for consistent, everyday immune support — not short-term stimulation.*
Shark liver oil has been traditionally valued for its unique lipid profile, particularly its naturally occurring alkylglycerols (AKGs). Unlike common fish oils that focus primarily on omega-3s, shark liver oil provides rare fats that support immune function and cellular communication. Deep Defense delivers these compounds in a whole-food form that works with the body’s natural defense systems rather than overstimulating them.*
We prioritize purity and potency with rigorous third-party lab testing at every stage of production. Transparency matters, so we make our test results available in our help center. You can learn more about our five-stage testing process in this blog article.
Our supplements come in amber glass bottles with metal lids (never plastic). Dark glass helps preserve nutrient integrity by protecting against light and oxygen, while eliminating the risk of microplastic leaching. It’s safer for you, better for the environment and fully recyclable — giving you peace of mind with every bottle.
Deep Defense is made from shark liver oil sourced from the longnose spurdog (Squalus blainville), a commercially fished species harvested along the west coast of Europe. Sharks are not caught for their livers. The entire animal is used for human consumption, and the livers, once discarded, are responsibly utilized to create this product. We firmly oppose shark finning and work with partners committed to sustainable fishing practices, education, and long-term marine conservation.
