UP165, A Standardized Corn Leaf Extract for Improving Sleep Quality and Mood State
UP165, a standardized Zea mays (corn) leaf extract, was evaluated for its effect on sleep quality and overall well-being in a double-blind, placebo-controlled clinical trial, administered orally at 250 and 500 mg/day. Participants (n = 45) (age range 19–73) consumed the supplement or placebo ∼60 min...

Sumario: | UP165, a standardized Zea mays (corn) leaf extract, was evaluated for its effect on sleep quality and overall well-being in a double-blind, placebo-controlled clinical trial, administered orally at 250 and 500 mg/day. Participants (n = 45) (age range 19–73) consumed the supplement or placebo ∼60 minutes before bedtime daily for 4 weeks. Measurements that were evaluated were as follows: daily sleep quality, as monitored by a fitness tracker; the Pittsburgh Sleep Quality Index (PSQI) for sleep quality and efficiency; salivary cortisol levels for stress; and Profile of Mood States (POMS) to assess general well-being. Participants who received UP165 showed a statistically significant and dose-correlated reduction in salivary cortisol (up to 36%); an increase in deep sleep time (up to 30 minutes); increased total sleep time (up to 10%); an improvement in sleep quality (up to 49%), and an enhanced POMS (36–58%). Participants in the UP165 group showed a sevenfold increase in deep sleep time and a 10-fold increase in PSQI sleep quality improvement compared to placebo. Collectively, UP165 is a safe nutritional supplement clinically proven for a 24-hour support with better quality and efficiency of sleep at night and an improved mood state and overall well-being during the day. The clinical study has been ISRCTN registered with study ID ISRCTN68282897. |
