Diet Mountain Dew is a zero-calorie citrus-flavored soda from the Mountain Dew brand, available in a convenient 24-count pack of 12 fl oz (355 mL) cans. This diet variation delivers the same bold, exhilarating citrus taste as original Mountain Dew with none of the sugar and zero calories per serving.

Each can is caffeinated and provides the signature intense refreshment Mountain Dew is known for. Sweetened with aspartame, acesulfame potassium, and sucralose, this is a popular choice for those seeking a low-calorie soda alternative. The product is Kosher certified and made with concentrated orange juice, citric acid, and natural flavor for its distinctive citrus character.
