The Associated Press reports that Lehi's XanGo has built a $1 billion business around its purple fruit juice tonic, which it claims boosts immunities.

"Music Man" Sen. Orrin Hatch, the snake oil-pusher's friend, says he chugs XanGo on a daily basis to wash down his supplement pills. "That's the only product they sell, and people are taking it around the world."

Hatch, of course, was the lead sponsor of the Dietary Supplement Act that allows the sale of supplements unless the Food and Drug Administration can prove them dangerous.

But a lab test paid for by the AP found XanGo's antioxidant power to be at the mid-point of ordinary fruit juices costing a tenth as much — "slightly higher than cranberry juice, but lower than black cherry and less than half the power of blueberry juice."
