A deeper look at the patented ingredients in Thorne Immune Activator 

Benicaros: Benicaros is a prebiotic that selectively targets good gut bacteria. Derived from the fiber-, carotenoid-, and mineral-rich carrot pulp left over from the production of carrot juice, Benicaros is a precision-extracted polysaccharide that has been clinically studied for its immune-supportive benefits.*  

• Trains the immune system for a faster and stronger response*
• Enhances immune system resilience and adaptability to immune stressors*
• Promotes a swift and strong immune response*
• Stabilizes the gut for optimal microbiome composition*
• Increases the number of short-chain fatty acid (SCFA)-producing bacteria, such as Firmicutes and Bifidobacterium* 
• Supports a healthy gut barrier* 

Why it matters: Benicaros helps to promote immune readiness by nourishing a healthy gut microbiome and protective gut environment.* 

MitoHeal: MitoHeal is a patented polyphenol blend of redcurrants and blackcurrants. Polyphenols are natural plant compounds that give foods their color and taste and protect them from damage. 

Why it matters: The polyphenols in MitoHeal serve as effective prebiotics to help balance the ratio of good and less beneficial bacteria in the gut while providing plant-powered antioxidant support that protect cells against oxidative stress.*
