Before 1948, the popular lemon-lime soda 7UP contained a curious ingredient: lithium citrate. Originally called "Bib-Label Lithiated Lemon-Lime Soda" upon its 1929 launch, it was advertised as a mood-boosting tonic. This unusual component was removed due to a 1948 ban by the U.S. Food and Drug Administration (FDA) that prohibited its use in soft drinks after reports of lithium toxicity and unregulated sales.
