THE GUT SEALER
AT-1001; Larazotide Acetate
Larazotide is designed to close the gaps between intestinal cells that cause "leaky gut." It blocks zonulin, a protein that opens these gaps and allows food particles and bacteria to leak into your bloodstream. Originally developed for celiac disease, it may help anyone with intestinal permeability issues.
