| **Overview** | 2'-Fucosyllactose (2'-FL) is a human milk oligosaccharide that acts as a prebiotic by selectively feeding beneficial gut bacteria. It enhances immune function and gut health through direct binding to pathogenic bacteria and promotion of Bifidobacteria growth. | Affron is a standardized saffron extract containing 3.5% lepticrosalides that supports mood regulation through serotonin pathway modulation. Clinical studies demonstrate up to 50% reduction in depression symptoms and enhanced cognitive function through its antioxidant properties. |
| **Mechanism of Action** | 2'-FL selectively binds to α-1,2-fucosyltransferase receptors on beneficial bacteria like Bifidobacterium longum, promoting their proliferation. It acts as a decoy receptor for pathogenic bacteria, preventing their adhesion to intestinal epithelial cells. The compound stimulates short-chain fatty ac | Affron's lepticrosalides, primarily crocin and safranal, modulate serotonin reuptake inhibition and increase dopamine and norepinephrine levels in synaptic clefts. These bioactive compounds also activate NMDA receptors and inhibit acetylcholinesterase, supporting cognitive function. The extract's an |
