Nuritas has launched PeptiSleep, a natural plant peptide ingredient derived from rice bran protein that supports all stages of sleep by reducing cortisol, a hormone responsible for stress and poor sleep. A pilot study using smart rings with sensors that measure biometrics indicates that 61% of participants fell asleep faster. In addition, people using PeptiSleep instead of a placebo experienced an increase of 17% in deep sleep, 13% in light sleep, and an average of 35 minutes of total sleep while also improving readiness and sleep scores.
