The immune support benefits of RMA are presumed to be locked in their content of sulfated polysaccharides as explained above. In addition, red macro algae are known to contain a high level of plant sterols and sterolins. These fatty alcohols and alcohol-sugar complexes are now known to stimulate the human immune response even though only a small fraction (2%-4%) of plant sterols are ever absorbed from the gastrointestinal tract. It is possible then that Gigartina RMA provides a two-pronged stimulus to the immune response.
The five species of wild harvested family Gigartinaceae red marine algae in this product provide a rich source of sulfated polysaccharides.
