Is Mountain Dew Vegan?

Original Mountain Dew and its mainstream variants (Code Red, Zero Sugar, Diet, Voltage, Baja Blast) contain no animal-derived ingredients. The sweetener is high fructose corn syrup, which is not filtered through bone char, so the bone char sugar concern that affects some cane-sugar sodas does not apply here. No carmine, gelatin, honey, dairy, or egg appears in any standard formulation.

PepsiCo confirms through its consumer FAQ that standard Mountain Dew sodas (Original, Diet, Zero Sugar, Code Red, Baja Blast, Voltage, LiveWire, and Kickstart) contain no gluten-source ingredients. PepsiCo does not pursue formal GFCO certification or print a gluten-free claim on the can, but the formulas contain no wheat, barley, rye, or oats. The important exception is Hard Mountain Dew, the alcoholic version made by Boston Beer Company using barley malt fermentation: that product is NOT gluten-free and poses a risk for people with celiac disease.

Most standard Mountain Dew sodas produced at the Wichita, KS facility are certified pareve by the Chicago Rabbinical Council (cRc) when they carry a 'KS' lot code. Regular Mountain Dew and Diet Mountain Dew sold in the US and Canada are generally acceptable without a kosher symbol on the label. However, Kickstart, Game Fuel, and Rise varieties contain grape juice, which under kosher law requires a visible K or recognized kosher symbol on the can or bottle before they can be consumed.

Yes, in a few ways that matter to vegans. UK and EU versions use sugar instead of high fructose corn syrup. The source of that sugar is not publicly confirmed by PepsiCo, and a portion of white cane sugar sold in those markets may or may not be filtered through bone char depending on the refinery. This is a processing concern (not a dietary ingredient), but strict vegans in those markets cannot confirm the sugar supply chain without direct manufacturer disclosure. Color choices and some flavor additives can also differ between markets due to regional regulations.

No credible source documents Mountain Dew ever containing a clearly animal-derived dietary ingredient such as gelatin, dairy, honey, or carmine. Brominated vegetable oil (BVO) was used as an emulsifier in LiveWire and a few other variants; BVO is derived from plant oils (corn or soy) so it was vegan even then. The FDA revoked BVO authorization in July 2024 with a compliance deadline of August 2025, and PepsiCo removed it from all products. The formula has always cleared the dietary vegan standard.

No, Yellow 5 (also called tartrazine) is a synthetic petroleum-derived dye with no animal ingredients. It is considered vegan by dietary standards. The ongoing concern is that regulatory agencies require animal testing for new food dye approvals and periodic safety reviews, meaning Yellow 5 has been tested on animals. Vegans who extend their definition to exclude all products associated with animal testing may choose to avoid it on ethical grounds, but this is a personal line rather than an ingredient-level distinction.

Yellow 5, the dye that gives Mountain Dew its distinctive green-yellow color, is made from petroleum and contains no animal ingredients, but it is still tested on animals by regulatory agencies. Strict ethical vegans who avoid products with ongoing animal testing may want to skip it on those grounds, though this is a personal line rather than a dietary ingredient concern.

Vegan options include Olipop Lemon Lime (plant-based, no artificial dyes), Spindrift Sparkling Water (fruit-juice-based, clean label), Zevia Mountain Zevia (stevia-sweetened, no artificial colors), Poppi Grape (prebiotic soda, vegan certified).

Mountain Dew does not carry a third-party vegan certification, so the verdict here is based on its current ingredient list and manufacturer information.
