EPAX® / Seamega XO®

A premium, ultra-purified fish oil, highly concentrated in omega-3 EPA and DHA

EPAX® and Seamega XO® are premium fish oils derived from wild fish, produced using high-tech purification processes to achieve a high concentration of omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), while ensuring very high purity.

These patented ingredients meet the strictest international quality standards, with rigorous control of environmental contaminants (heavy metals, dioxins, PCBs) and oil oxidation. Thanks to their excellent bioavailability, they provide essential omega-3s directly usable by the body.

EPA and DHA are major components of cell membranes. They play an essential role in the functioning of the heart, brain, and vision, and contribute to maintaining a physiological inflammatory balance.

Studied benefits

Support for cardiovascular health

EPA and DHA fatty acids contribute to the normal functioning of the heart. Studies show that regular supplementation helps maintain optimal cardiovascular function.

Support for brain functions

DHA is an essential component of neuronal membranes. It contributes to normal brain function and helps maintain cognitive performance throughout life.

Contribution to maintaining vision

DHA also helps maintain normal vision by contributing to the structure and function of the retina.

Physiological inflammatory balance

Omega-3s EPA and DHA are involved in the production of lipid mediators that regulate the inflammatory response and maintain tissue balance.

Lasting cell protection

By integrating into cell membranes, omega-3s contribute to their flexibility, integrity, and proper functioning, thus contributing to the overall health of the body.
