From a performance standpoint, the 1:1 zinc-carnosine complex provides targeted support for the gastric mucosa, while the herbal blend adds plant-based relief from bloating. The addition of L-glutamine and a 5 billion CFU probiotic blend aims to strengthen the gut barrier and foster a balanced microbiome.
