Marine Phytoplankton contains a wide array of substances, which supports and modulate the immune system. The two most important substances are: Omega 3 fatty acids and carotenoids (pigments). (1)(2)(3)(4)(5)(6)(7)

These substances have the potential to more rapidly active the immune system and through the production of mediators that stimulate the body to adequately deal with any kind of virus, bacteria or yeast (8). In the final phase of acute inflammation, the Omega-3 fatty acids produce anti-inflammatory mediators, making sure the body returns to its natural state (9). 

Other ingredients such as lipopolysaccharides, peptides, minerals and vitamins also improve the global functioning of the immune system (10). 

Some of these substances have multiple functions, like astaxanthine supporting the immune reaction as well as detecting and scavenging harmful oxygen molecules, giving the potential to detoxify the body (11) (12).
