Is Celsius Vegan?
Vegan
Vegan.org Certified VeganCelsius energy drinks (all major lines: Originals, HEAT, Stevia, On-the-Go) are certified vegan, with no animal-derived ingredients confirmed by the brand's own FAQ and third-party vegan certification.
The catch: Taurine is the one ingredient that raises eyebrows, it occurs naturally in animal tissue, but the taurine in Celsius (and virtually all commercial energy drinks) is synthetically produced, and Celsius carries explicit vegan certification confirming this.

Celsius states on its official FAQ that "CELSIUS and CELSIUS ON-THE-GO are certified vegan," and the brand's full product portfolio, including Celsius Sparkling, Celsius HEAT, Celsius Stevia, and the powder On-the-Go sticks, share the same certified-vegan status. Taurine is the only gray-area ingredient: naturally an animal-derived amino acid, but the commercial form used in energy drinks (including Celsius) is lab-synthesized and confirmed vegan by the certification.
Natural flavors are present but Celsius's vegan certification covers the full formula; no carmine, gelatin, or other animal dyes/agents appear in any documented Celsius ingredient list. No significant US vs.
international formulation differences have been documented for vegan status, and Celsius also states it does not conduct animal testing.

Frequently asked
Is Celsius Vegan?
Celsius energy drinks (all major lines: Originals, HEAT, Stevia, On-the-Go) are certified vegan, with no animal-derived ingredients confirmed by the brand's own FAQ and third-party vegan certification.
Is Celsius gluten-free?
Yes. Celsius lists gluten-free as a key product attribute across its lineup. The official Celsius FAQ confirms this for the main CELSIUS and CELSIUS ON-THE-GO lines.
Is Celsius kosher?
Yes, for US products. The Celsius FAQ lists kosher as a confirmed attribute. The UK version sold on sites like Protein Package does not list kosher certification, so this appears to be a US-market status.
Does Celsius contain milk or is it made on shared equipment with dairy?
Celsius states it has tested and verified that milk and its derivatives (whey, caseinate, etc.) are not present in its formulas. The company does not publish a shared-equipment or cross-contamination disclosure, so if you have a severe dairy allergy, Celsius recommends not consuming the product out of an abundance of caution.
Are UK or international versions of Celsius also vegan?
The UK version uses acesulfame K as the sweetener instead of sucralose, and does not list chromium chelate. UK retailer listings (such as Protein Package) mark the product vegan and gluten-free. Kosher is not listed for the UK version. Neither sweetener is animal-derived, so the vegan status is the same, but the exact formulas do differ between markets.
Was Celsius ever non-vegan?
No documented evidence exists that any Celsius product line ever contained animal-derived ingredients. The brand has confirmed vegan certification and states it does not test on animals. No reformulation away from animal ingredients has been reported in any public ingredient history.
What is the catch with Celsius?
Taurine is the one ingredient that raises eyebrows, it occurs naturally in animal tissue, but the taurine in Celsius (and virtually all commercial energy drinks) is synthetically produced, and Celsius carries explicit vegan certification confirming this.
What can I use instead of Celsius?
Vegan options include Reign Storm (Monster's clean-energy line, vegan), Ghost Energy (vegan-friendly, collabs with candy brands), Alani Nu Energy (vegan, 200mg caffeine), Zevia Energy (Non-GMO Project Verified, vegan, stevia-sweetened).
