Dr. Enuf's Slogans & Taglines

Dr. Enuf is a brand of soft drink bottled by Tri-City Beverage in Johnson City, Tennessee. Created in 1949 by Chicago chemist William Mark Swartz as a vitamin-fortified alternative to sugar-laden sodas, the beverage was acquired by Charles Gordon of Tri-City Beverage and launched in the Tri-Cities region the same year. The lemon-lime flavoured drink is enriched with B vitamins, caffeine, potassium, and iodine, and was originally marketed as a dietary supplement and energy booster. Early promotions claimed it could relieve fatigue and digestive ailments, positioning it as a medicinal tonic at a premium price point. Over seven decades, the brand has maintained its original recipe while expanding to include diet and herbal variants. Sold primarily in its iconic green glass bottles across East Tennessee and select southeastern retail locations, Dr. Enuf has cultivated a devoted regional following. Brand messaging has been anchored by the enduring slogan "Enuf is Enough!", reflecting its identity as the original fortified soft drink.
