Vintage Conway Stewart “Guinness is good for you”, Guinness Advertisement from 30s , NIPPY No 3

Through much of the 20th century, doctors thought Guinness had medicinal properties. Even until the 1950s mothers in Irish hospitals were given Guinness after giving birth because of the high iron content.

So it’s no surprise that the Benson agency’s simple tagline “Guinness is good for you” was a hit with consumers when it was introduced in 1929. The slogan remained the foundation of the brand for the next 40 years, until the advertising environment became a little more regulated.
