"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 BillboardHot Mainstream Rock Tracks chart and reached number three on the BillboardHot 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.
The song's music video revolves around imagery seen in the items of a cubicle. The images become real, life size landscapes that vocalist Pete Loeffler is seen drifting through. The video is apparently a reference to the many different kinds of hallucinations experienced by misdiagnosed ADHD patients who take, and develop an addiction to, Ritalin.
