I'd heard caffeine and beet juice were banned during an emergency meeting at the UCI's December conference, voted in with overwhelming support from the US, Russian and British cycling associations, and over the objections of the French conference, and on the condition no one, including USAC, would implement the rule until a reliable test for beet juice and coffee could be developed.
I believe there is an exception for single speed cyclocross.
I can not speak to any benefit beet juice has provided me. I tried it once, for the PDX Ronde, but can't say it helped me at all - I was probably one of the last ten people to finish. Finishing was good, but I don't credit the beet juice.
