The ingredients in Perm A vite® are known to nutritionally support the epithelial lining, which may support intestinal permeability within normal functional levels.

Remedial support with suitable doses of specific nutrients can greatly facilitate the process of renewal of the tissues of the gut lining, achieving significantly more progress than dietary or lifestyle measures alone.
