A.C. Formula II supports gastrointestinal health by promoting a balanced intestinal microflora. It combines caprylic acid, calcium undecylenate, and herbal extracts—including grapefruit seed extract and berberine sulfate—to help maintain a healthy microbial environment in the colon. Fatty acids act synergistically with buffering minerals to sustain activity along the GI tract, supporting microbial balance and digestive function.
