"Caffeinated sodas have never been banned from our campus", BYU spokeswoman Carri Jenkins said by phone, but she clarified that dining services has not offered them since the 1950.
Mormonism prohibits the drinking of alcoholic and caffeinated beverages, but The Church of the Latter-day Saints ruled in 2012 that soft drinks do not conflict with church belief.
Sales of highly caffeinated energy drinks are still banned.
A 2012 "Getting it Right" posting on the church's website explained, "The Church revelation spelling out health practices (Doctrine and Covenants 89) does not mention the use of caffeine".
Whether it's been an espresso-laced coffee or a cold Coca-Cola, caffeinated drinks have fueled campuses for decades.
Jenkins noted that students have always been free to bring their own caffeine-filled beverages onto campus.
The same can't be said of the university's campus in Rexburg.
Mormons are encouraged to maintain a healthy lifestyle, but it was a long-held misunderstanding that the faithful were barred from consuming caffeine.
Mormons neither smoke nor drink alcohol, coffee, or tea, as it is prohibited by their religion. "It's been a big game changer, even just day one", said Mckay Murphy, a junior statistics major from Springville, Utah. Employees don shirts that say, "I'm a caffeine dealer".
In the FAQ, BYU said it was adjusting to meet consumer demand now. In a Facebook post, Caffeine Corner said, "Sounds like we're still in business".
