Science-Backed, Stomach-Approved

Our formulations are meticulously crafted with scientifically-proven ingredients and rigorously tested to ensure maximum effectiveness and gentleness without gas, bloating or digestive issues.

They are lab tested and certified low in fermentable carbs (FODMAPs). Reducing FODMAPs (e.g wheat, dairy, soy, etc) has been scientifically shown to reduce symptoms like diarrhea, bloating and abdominal pain by reducing fermentable carbs that can trigger them.

"As a dietitian, I trust Casa de Sante to provide top-quality, gut-friendly supplements." – Jane Smith, RDN
