PRALISUR™: Algae-sourced Immune Support for Dogs
PRALISUR is a natural* ingredient that contains more than 50% beta-1,3-glucans derived from dried algae. Beta-glucans are glucose polysaccharides naturally occurring in the cells of plants, cereals, and fungi. The beta-1,3-glucan sourced from algae has been shown to stimulate and activate the immune systems of animals.
Research on beta-glucan dates to the 1940s, and its efficacy and mechanism on the immune system has been well documented in a significant number of peer-reviewed studies. Beta-glucans have been used in livestock and aquaculture applications for many years, and can be found in a wide variety of human food and nutraceutical products for immune support.
In dogs, it has been shown that beta-1,3-glucan can:
Other potential functional benefits of beta-glucan in dogs have been demonstrated in various research publications as a supportive approach for atopic dermatitis,3 for inflammatory bowel disease4 and for steoarthritis.5
Why choose PRALISUR over other sources of beta-glucan?
Algae-sourced beta-glucans are unique in how they can support a dog’s natural defense system at the cellular level, in comparison to beta-glucan from other sources.6
Structural differences impact the function of beta-glucans in the body, as different sources have unique molecular structures. Among the various sources of beta-glucan, PRALISUR contains one of the highest concentrations of linear beta-1,3-glucan. PRALISUR is activated during the digestion process, which easily breaks down the protein-rich skin of algae to release (1,3) algae beta-glucans. After digestion, beta-1,3-glucans are absorbed in the small intestines, where they can support a healthy immune response.
