Celsius vs Ghost Energy: Caffeine (200 vs 200 mg), Sweeteners

Celsius Sparkling Orange and Ghost Energy Citrus both list 200 mg of caffeine per can, but Celsius packs it into a smaller can, so it carries more caffeine per fluid ounce: about 16.7 mg versus 12.5 mg.

The cans differ in size: 12 fl oz for Celsius and 16 fl oz for Ghost. The two brand panels also differ on calories, sodium, sweeteners and added ingredients. Label figures below come from each brand's own panel.

Key takeaways

• Per can, both list 200 mg of caffeine. Per fluid ounce, Celsius is about 16.7 mg and Ghost is about 12.5 mg.
• Celsius lists 10 calories and 5 mg sodium per 12 fl oz on its brand label (Open Food Facts lists 10 mg sodium). Ghost lists 5 calories and 30 mg sodium per 16 fl oz.
• Celsius's brand label names sucralose only. Ghost's panel lists sucralose and acesulfame potassium.
• The added ingredients differ in kind, and neither brand discloses the amount of every ingredient.

Celsius Sparkling Orange vs Ghost Energy Citrus at a Glance: Side-by-Side Label Table

The table uses each brand's own label panel: the Celsius Sparkling Orange label and the Ghost Energy Citrus product page. Because the cans are different sizes, the per-ounce rows are calculated from the printed label numbers, not stated by either brand.

How Much Caffeine Is in Each Can, and How Much Per Ounce?

Each can lists 200 mg of caffeine, so the per-can totals are equal. The per-ounce figures differ because the cans hold different volumes.

Does Ghost Have More Caffeine Than Celsius?

No. Both labels list 200 mg per can, so neither can contains more caffeine than the other. Ghost's can is larger, so its caffeine is spread across 16 fl oz instead of 12 fl oz.

Which Has More Caffeine per Ounce, Celsius or Ghost?

Celsius Sparkling Orange has more caffeine per fluid ounce, about 16.7 mg compared with about 12.5 mg for Ghost Energy Citrus. These figures are calculated by dividing the 200 mg label amount by each can's printed volume.

The FDA has cited 400 mg a day as an amount not generally associated with negative effects for most adults, and describes that as about two to three 12 fl oz cups of coffee, according to the FDA's caffeine guidance. Two cans of either drink would reach 400 mg. The same FDA guidance notes wide variation in how sensitive people are to caffeine and how quickly they eliminate it. For a related look at caffeine in another pairing, see Celsius vs Red Bull Caffeine: 200 mg vs 80 mg, Compared.

The Celsius panel states 'NOT RECOMMENDED FOR PEOPLE WHO ARE CAFFEINE SENSITIVE, CHILDREN UNDER 18, OR WOMEN PREGNANT OR NURSING' and 'DO NOT EXCEED (2) SERVINGS PER DAY.' The Ghost caution says the product is intended for healthy adults 18 years or older, advises against use if you are sensitive to caffeine or combine it with caffeine or stimulants from other sources, and says it is not for women who are pregnant, nursing, or trying to become pregnant.

The FDA advises people who are pregnant, trying to become pregnant or breastfeeding to talk with a health care provider about limiting caffeine. It also notes that medical experts advise against energy drinks for children and teens, according to the American Academy of Pediatrics.

Neither brand states whether its formula has changed since these panels were published.

Which Sweeteners Does Each Drink List, and How Do They Compare?

Celsius's brand label lists sucralose as its only sweetener. Ghost's panel lists sucralose and acesulfame potassium. The Open Food Facts record for Celsius Sparkling Orange matches the brand label: sucralose is the only sweetener. Neither brand discloses the milligrams of either sweetener in a can.

What Is Sucralose, and What Does the FDA Say?

Sucralose is an FDA-approved sweetener that the agency describes as about 600 times sweeter than table sugar. According to the FDA, sucralose was approved for 15 food categories in 1998 and as a general-purpose sweetener in 1999, after reviewing more than 110 studies, per the FDA's sweeteners page. The FDA's acceptable daily intake (ADI) for sucralose is 5 mg per kilogram of body weight per day, as stated on that FDA page.

What Is Acesulfame Potassium, and What Does the FDA Say?

The FDA states that acesulfame potassium is approved for use in food as a sweetener. It is about 200 times sweeter than table sugar and is often combined with other sweeteners. According to the same FDA page, it was approved for specific food categories in 1988 and as a general-purpose sweetener in 2003, after reviewing more than 90 studies. The FDA's ADI for acesulfame potassium is 15 mg per kilogram of body weight per day.

An ADI is expressed per kilogram of body weight. Because neither brand discloses sweetener amounts per can, these labels alone do not let a reader calculate how much sweetener a can contains.

How Many Calories Are in Celsius vs Ghost Energy Citrus?

Celsius Sparkling Orange lists 10 calories per 12 fl oz can. Ghost Energy Citrus lists 5 calories per 16 fl oz can. Calculated per fluid ounce, that is about 0.8 calories for Celsius and about 0.3 calories for Ghost.

The Ghost panel lists 1 g total carbohydrate (less than 1% DV), 0 g total sugars and 0 g added sugars. The Celsius panel prints 'Total Carbohydrate 0mg.' Carbohydrate is normally expressed in grams, so this unit is unusual and is worth checking on the can itself. Open Food Facts also lists 10 kcal per serving for the Celsius product, which matches the brand panel.

The Nutrition Facts panel on the can in front of you is the source to check for calories and carbohydrates, since retail pages can reproduce panels with small differences.

How Much Sodium Is on Each Label, and What Do the Panels Disagree On?

The Celsius brand label image lists 5 mg of sodium per 12 fl oz can. The Ghost brand panel lists 30 mg per 16 fl oz can, which is 1% DV. Calculated per fluid ounce, that is about 0.4 mg for Celsius and about 1.9 mg for Ghost.

Open Food Facts lists 10 mg for the same Celsius can; this article uses the brand label's 5 mg. Readers comparing sodium should check the panel on their own can.

When reading any energy drink label, look for:

• The serving size line, which sets the basis for every number on the panel
• The caffeine statement, which may appear on the front, side or in the panel
• The sweetener names in the ingredient list
• Any 'do not exceed' or caution line on the side panel

How Much Taurine Is in Ghost Energy, and Which Other Actives Are Listed?

Ghost Energy Citrus lists 1000 mg of taurine per 16 fl oz can. Celsius lists taurine in its ingredients but does not disclose an amount.

Celsius's ingredient list includes taurine, guarana seed extract, green tea extract, ginger root extract and glucuronolactone, alongside B vitamins, calcium carbonate and chromium chelate. The Celsius product page says the brand uses guarana seeds rather than roots, and describes its green tea extract as containing a specific ratio of EGCG. The amounts of taurine, guarana, green tea extract, EGCG, ginger and glucuronolactone are not disclosed.

Ghost's panel lists taurine at 1000 mg, Carnipure L-carnitine L-tartrate at 1000 mg, natural caffeine from coffee bean at 200 mg, Alpha-GPC (50%) at 150 mg, NeuroFactor coffee fruit extract at 100 mg, and AstraGin root extracts at 25 mg (10:1 Astragalus membranaceus and 50:1 Panax notoginseng).

The FDA page cited in this article does not address taurine, L-carnitine, Alpha-GPC or AstraGin, so no FDA status is attributed to them. Readers who want to compare any of these ingredients more closely can use the ingredient-by-ingredient explanations in the Aurascan app.

Are Vitamins and Minerals Listed Differently on Each Can's Label?

Yes. The Celsius panel lists vitamin C at 60 mg (70%), riboflavin at 1.7 mg (130%), niacin at 20 mg (130%), vitamin B6 at 2 mg (120%), vitamin B12 at 6 mcg (250%), biotin at 300 mcg (1000%), pantothenic acid at 10 mg (200%), calcium at 50 mg (4%) and chromium at 50 mcg (140%).

The Ghost panel lists vitamin C at 90 mg (100%), niacin at 16 mg (100%), vitamin B6 at 1.7 mg (100%) and vitamin B12 at 2.4 mcg (100%).

The percent Daily Value figures are reproduced as printed on each panel. A higher number of listed nutrients does not indicate anything about how a person's needs are met, which depends on the rest of their diet.

Which Label Details Are Not Disclosed?

The following are not disclosed on either brand's panel:

• Milligrams of sucralose or acesulfame potassium in either can
• Celsius amounts for taurine, guarana seed extract, green tea extract (including EGCG), ginger root extract and glucuronolactone
• How much of Celsius's 200 mg of caffeine comes from guarana versus added caffeine
• How Ghost's 200 mg splits between coffee bean caffeine and any caffeine in its coffee fruit extract
• Whether either formula has changed since the panels were published
• Clinical results for these specific cans

The Celsius label image on the brand site appears to date from 2023 based on its file path, and a 2026 Open Food Facts record matches its ingredient list. The Ghost figures come from the brand panel alone, because its Open Food Facts text is partly garbled.

These labels cannot show how any individual will respond to either drink. Readers who want to understand a specific ingredient can scan the product yourself.

Aurascan explains each ingredient one by one with cited evidence rather than a single score, and it pulls product data from Open Food Facts, USDA and barcode databases. Verdicts are per ingredient (Clean, Mixed or Flagged), never a numeric score, and Aurascan has no sponsors. Scan the label on the can in front of you to see each ingredient explained for yourself.
