In a small randomized, double-blind, placebo-controlled clinical trial on 35 healthy adults, drinking 120 mL/day of goji berry juice significantly improved energy level, athletic performance, quality of sleep, ease of awakening, ability to focus on activities, mental acuity, calmness, regularity of gastrointestinal functions and feelings of health, contentment and happiness, and significantly reduced fatigue and stress over a period of 14 days. The authors conclude, "The data strongly suggest that further research is indicated to confirm and extend knowledge of the potential effects of Lycium barbarum [goji berry] upon human health."
