"Vitamin C" is a song by the krautrock band Can on their 1972 album Ege Bamyasi. It is known for its thick bass line, bouncy percussion and catchy chorus, which has Damo Suzuki repeating the line "Hey you! You're losing your Vitamin C". Considering its short length and relatively standard song structure, it is one of the band's more conventional songs.

It was featured in Samuel Fuller's German television Tatort production Kressin & die tote Taube auf der Beethovenstraße (Dead Pigeon on Beethoven Street) in 1973, and then also released as a single with the B-side "I'm So Green".

In 1997, an 8-minute version of the song, remixed by British musical outfit U.N.K.L.E., was featured on Can's double remix album Sacrilege.
