Testimonials

"I have been recommending and providing PreProtein to my bariatric surgery patients for a few years now. It provides a high amount of protein in such a small volume and is very low viscosity. My patients enjoy the flavor of it and can easily incorporate it into their post-op diet routines."
Julymar M., DietitianSouth San Francisco, CA
"I had Bariatric surgery in July of 2021 and had consistent issues finding protein that I could tolerate. I’ve spent so much money on shakes, powders, among other things and just couldn’t deal with any of them. But this PreProtein liquid that a TikToker promoted is awesome!! I absolutely love it."
Tonya H., Bariatric patient
"We have seen good results from our inpatient use of PreProtein in both our wound care and protein-energy malnutrition patients. We are incorporating PreProtein into our hospital's nutrition program and found it is an effective and quality nutritional supplement with a high amount of protein."
Francisco T., Emergency MedicineMiami, FL
"As a renal dietitian, we always look for different ways to improve patients' acceptance of new protein supplements to maintain healthy albumin levels. We chose PreProtein for our facility for our ONS program due to the great flavor and low viscosity of the product, along with good patient compliance."
Robbie M., DietitianFt. Lauderdale, FL
