Went to see about this Brazi Jujube drink on the site where you had  posted about it.  The text said that the fruit has been used for over 4,000 years to help people improve their quality of life.  I never heard of it, and if anyone thinks that it is the same kind of energy drink as Redbull, or one of the others, it isn’t like that at all.  Apparently, this fruit cleanses the blood, and boosts the immune system.  Chinese herbalists used it to help patients cleanse their spleen, liver and even the heart.   Also, on the site, they suggest that having a small shot glass of the jujube drink, helps to slow the aging process.  I want to do more research and find out what kind of manufacturing process is involved in making the fruit into an energizing drink.
