I'll also add this, if you don't keep an open mind, you are guaranteed not to find any health solutions.
This is not to say XanGO is a good product, I think it is probably crap.
1) Processed: Puree is heated, heat destroy nutrients, specifically phytonutrients. XanGo cannot make claims based on the results from studies with mangosteen for this reason, studies must be done on XanGo alone.
2) preservatives : Freshly squeezed mangosteen does not last for 2 months on a shelf, so there are heavy preservatives involved in storing this product.
MSG is not good for you, but it's everywhere because it tastes great!
4) Although studies have shown that it does XYZ, there are studies of oranges, apples, and other fruits and vegetables showing similar benefits.
Having said that... I might try it for a month to see. I consider it an investment. Maybe I'm a suc***? I'm recovering from liver cancer/hepatitis and I can feel everything in my body, I can tell you exactly what works and what doesn't (for me at least).
Hopefully I can get back to you and tell you about my experience. I know you don't like testimonials and I won't change your mind, but I am HIGHLY skeptical about it.
