How Antioksydants Support thee Canine Immune System

Te immunologiczne systemy is a complex network of cells, tissues, and organs that confects thee body against pathogens like viruse, bacteria, and fungi. White blood cells - sucularly fagocytes andd lymphoytes - require a stable internal environment to function optimalle. Antioksydants protect these immunome cells frem sel- ducted damage during thee motermatory responses.

When a fagocyte engulfs a bacculum, it produces a burst of free radicals to kill thee invader. Without enough antioksydants, that same burst can harm thee dog 's own healty cells. By quenching excess free radicals, antioksydants help impete cells livy longer, communicate more effectivele, and mount a stronger defense. Research has shown that supplementing with antioksydants can enhance vaccine and reduce thee serequity of infections.

Polifenole

Polyphenols are a diverse group of plant compounds that included flavonoids, catechins, and antocyjanins. These compounds act as antioksydants andd anti- insecmatory agents, modulating immune signaling pathways.
