On Chowhounds,whats my craving messege board,i saw your question about josta.Well,here is the scoop on that.
It contained more than caffine,it had something called guranna(sp?),which gives a massive speed-like boost.Guranna is so potent,u cannot buy it straight at the health food store,and when u do get it in certain body building shakes and so on,it is mixed with other things to balance it out.
The problem with Josta,was it contained more than the legal amount of guranna,and when it was discovered people we flying high on it,they pulled the stuff.I even heard it was stronger than caffine,and alot like ginsing,but more potent.
Personally,I think they could have just lowered the amount and made it taste the same,but I guess they were sillyheads huh?
Hope that helped ya!
Natalie(ps,mind u,this is what i heard about the product ;)
Well, I don't really know much about Josta, but I know a little about guarana and wanted to correct a few inaccuracies. As Melanie said, it's a berry (also called a bean) and, much like coffee and cocoa beans, the only active ingredient scientists have isolated at this point is caffeine. (The active energizing ingredients in ginseng, on the other hand, are a group of compounds known as ginsenosides.)
Guarana is, in fact, available in health food stores in "pure" form, at least in the state of NY. I have a bottle in my medicine cabinet. One capsule contains only about 90 milligrams of caffeine. In contrast, the FDA cautions against intaking more than 400 milligrams a day (the equivalent of approximately 4 cups of coffee).
Finally, while the FDA does monitor caffeine amounts in products (and it's possible that Josta was yanked from shelves because it exceeded safe levels), the vast majority of herbal supplements are not subject to FDA restrictions. My resource of choice in learning about herbs is the PDR Guide to Natural Medicines and Healing Therapies.
I may be wrong, but I think that Josta was actually manufactured by Pepsi, in an attempt to bring a popular type of soda in Brazil to the U.S. as an alternative to colas. I suspect that it was not successful enough to roll it out nationally and was discontinued due to poor sales, not because of violating any government regulations. You can find guarana in a lot of 'new age' beverages these days.
