Why I Created These Formulas

Standard supplements aren't designed for GLP-1 patients. Your stomach empties 30-50% slower. Food sits longer. Standard fiber causes more bloating, not less. Standard protein powders feel like a brick.

I formulated Casa de Sante products for exactly this: gentle formulas that work with slowed digestion, not against it. Every ingredient is chosen for tolerability first, efficacy second.

  • ★★★★★

    “Week 2 on semaglutide, the bloating and nausea made me want to quit. I added Casa de Sante’s digestive support and it was a game-changer. Meals sat better, less discomfort, and I stopped dreading dose day. It’s now part of my weekly routine.”

    “I was losing weight, but also felt flat and weak. The GLP-1 Muscle Defense combo made it easier to hit my protein intake without upsetting my stomach. My strength stopped sliding, my energy came back, and my labs looked better at follow-up.”

  • ★★★★★

    “I didn’t expect constipation to be the hardest part of GLP-1s. I tried random gut products and felt worse. Casa’s low FODMAP approach felt gentle and predictable and my regularity improved without cramps or urgency. I wish I’d started sooner.”
