Goji berries (Lycium barbarum), sweet, filling, and rich in vitamin A, potassium, non-heme iron, and selenium, are generally consumed as juice or dried fruit. In the study of the general effects of goji, researchers gave 34 participants 120 milliliters of pure juice per day or placebo.

They examined “general feelings of well-being, neurologic/psychologic traits, gastrointestinal, musculoskeletal, and cardiovascular complaints as well as any adverse effects. Also, measures of body weight, body-mass index, blood pressure, pulse rate, and visual acuity were assessed….”

Significant differences between day 1 and day 15 were found in the goji juice group including “increased ratings for energy level, athletic performance, quality of sleep, ease of awakening, ability to focus on activities, mental acuity, calmness, and feelings of health, contentment, and happiness,” said the researchers.

The juice “also significantly reduced fatigue and stress, and improved regularity of gastrointestinal function,” the report added.

In contrast, the placebo group showed only two significant changes (heartburn and happiness). No significant changes in musculoskeletal or cardiovascular complaints were observed in either group. Body weight was not significantly different between groups or between day 1 and day 15 for either group.

“These results clearly indicate that daily consumption… increases subjective feelings of general well-being, and improves neurologic/psychologic performance and gastrointestinal functions,” the study noted.

This randomized, double-blind, placebo-controlled clinical trial is the first study reported from outside China that has examined the general effects of the orally consumed goji berry.
