Vasoactive Intestinal Peptide (VIP) offers broad benefits, primarily by reducing inflammation, modulating the immune system (especially for autoimmune issues like CIRS), supporting neurological health (brain fog, neurodegenerative diseases), improving respiratory function (airway relaxation, oxygenation), and enhancing gut health (motility, secretion). It also boosts circulation, helps balance hormones, regulates circadian rhythms, and promotes cellular repair, making it valuable for chronic inflammation, immune support, cognitive clarity, and cardiovascular health.
