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.

Why Standard Supplements
Don't Work on GLP-1
GLP-1 medications change how your body processes everything. Gastric emptying slows by 30-50%. Nutrient absorption shifts. Standard supplements, formulated for normal digestion, often make things worse. Our formulas are designed from the ground up for the GLP-1 gut: gentle fibers that don't cause gas, pre-digested proteins with enzymes built in, nutrients in forms your compromised system can actually absorb.

-
★★★★★
“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.”
Megan -
★★★★★
“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.”
DR K. -
★★★★★
“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.”
James T.
