Abstract: Described herein is an innovative composition that improves sleep quality. This composition includes two important systems: 1) a sleep-inducing system that is being used for the first time in food and beverage products; and 2) a unique stabilizer system that provides a robust rheology and greater stability than other stabilizers. The two systems can be incorporated, individually or in combination, into food and beverage products, including but not limited to protein shakes and powders. Together, they enable this composition to aid in relaxation and optimal sleep quality, better sensory taste experiences than current market products, longer shelf life and robust stability. This disclosure also addresses a relevant need in the art for a beverage composition that promotes calmness and reduces stress by using natural ingredients, more specifically made from milk casein.
