Go­ji Berries con­tain polysac­cha­rides which for­ti­fy the im­mune sys­tem. About 36% of the sug­ars found in Go­ji Berries are polysac­cha­rides. A polysac­cha­ride found in this fruit has been found to be an an­ti-​ag­ing sec­re­t­a­gogue.
As we age, we pro­duce less and less Hu­man Growth Hor­mone (HGH). The de­creas­ing lev­els of HGH have been linked to symp­toms of ag­ing. Go­ji Berries are the on­ly food known to help stim­u­late the hu­man body to pro­duce more HGH nat­u­ral­ly. This fac­tor alone makes the Go­ji Berry per­haps the worlds great­est an­ti-​ag­ing su­per­food.
Go­ji Berries are some of the high­est an­tiox­i­dant con­tain­ing foods in the world. Go­ji Berries typ­i­cal­ly con­tain 2-​4 times the amount of an­tiox­i­dants found in blue­ber­ries.

Go­ji Berries have been tra­di­tion­al­ly re­gard­ed as a longevi­ty, strength-​build­ing, and po­ten­cy food of the high­est or­der. In sev­er­al study groups with el­der­ly peo­ple sev­er­al ounces of Go­ji Berries were giv­en once a day for 3 weeks. Many ben­e­fi­cial re­sults were ex­pe­ri­enced and 67% of the pa­tients T cell trans­for­ma­tion func­tions tripled and the ac­tiv­i­ty of the pa­tients white cell in­ter­leukin-​2 dou­bled. In ad­di­tion, the re­sults showed that all the pa­tients ex­pe­ri­enced an up­lift­ed spir­it and more op­ti­mism. Ap­petite im­proved in 95% of the pa­tients, and 95% of the pa­tients slept bet­ter.

The famed Li Qing Yuen, who pop­u­lar­ized gin­seng in Chi­nese cul­ture and who ap­par­ent­ly lived to the ripe age of 252 years (1678-​1930), con­sumed Go­ji Berries dai­ly. The life of Li Qing Yuen is the most well-​doc­u­ment­ed case of ex­treme longevi­ty known.
