Goji Berry Supplementation May Prevent Macular Degeneration.

Researchers conducted a double-blind, randomized, placebo-controlled trial in healthy elderly subjects to determine the effects of goji berry on macular characteristics and plasma zeaxanthin and antioxidant capacity levels.

The results revealed that those in the placebo group were found to have hypopigmentation and soft drusen accumulation in the macula, whereas those in the goji berry group remained stable. It was also found that both plasma zeaxanthin level and antioxidant capacity increased significantly in the goji berry group by 26% and 57%, respectively, but did not change in the placebo group. No participants reported any adverse reactions to the goji berry formulation. These findings suggest that goji berry supplementation increases plasma zeaxanthin and antioxidant levels as well as protects from hypopigmentation and soft drusen accumulation in the macula of elderly subjects.
