"Vitamin R (Leading Us Along)" is a single from Chevelle's album This Type of Thinking (Could Do Us In). It was their second number-one hit on the Billboard Hot Mainstream Rock Tracks chart and reached number three on the Billboard Hot Modern Rock Tracks chart. In interviews, it has been stated that "Vitamin R" is Ritalin. The song was written about a friend of the Loeffler brothers, who was misdiagnosed with ADHD, and developed an addiction to Ritalin. As a result, he would often do crazy and odd things, such as drive around aimlessly for hours, determined to hear a specific song on the radio.
