We’ve based our decision to use bovine collagen due to the extensive research and high-quality studies showing bovine collagen’s effectiveness. SQINTEA collagen demonstrably improves reduction of wrinkels1 and supports skin elasiticiy2 – clinical proven. The importance of both taste and efficacy are cornerstones of our product formulation, and we are extremely rigorous with our collagen source. SQINTEA collagen is kosher and allergen- hormone-, steroid- and antibiotic-free as well as independently tested for contaminants such as heavy metals, herbicides, insecticides, and pesticides.
