Why do people use goji berries?

Goji berries have been used for 6,000 years by herbalists in China, Tibet and India to:

  • protect the liver
  • help eyesight
  • improve sexual function and fertility
  • strengthen the legs
  • boost immune function
  • improve circulation
  • promote longevity
Goji berries are rich in antioxidants, particularly carotenoids such as beta-carotene and zeaxanthin. One of zeaxanthin's key roles is to protect the retina of the eye by absorbing blue light and acting as an antioxidant. In fact, increased intake of foods containing zeathanthin may decrease the risk of developing age-related macular degeneration (AMD), the leading cause of vision loss and blindness in people over the age of 65.

In recent years, goji juice has become popular as a health beverage. Companies marketing goji juice often mention the unsupported claim that a man named Li Qing Yuen consumed goji berries daily and lived to be 252 years old. Marketers also list extensive health benefits of goji juice, even though there are few published clinical trials in humans.
