Bloom and Celsius are both sold as energy drinks, but their formulas are not identical. Bloom Nutrition’s Sparkling Energy provides natural caffeine from green coffee bean extract, while standard CELSIUS provides 200 mg caffeine and uses ingredients including green tea extract, guarana, taurine, ginger and vitamins. (Bloom Nutrition)

For this comparison, Bloom means Bloom Nutrition Sparkling Energy and Celsius means standard CELSIUS, not Celsius Essentials or Celsius Hydration. Both brands have additional products, so the exact product matters. (Bloom Nutrition)

Which Has More Caffeine?

Celsius has slightly more caffeine.

For the standard products:

Bloom: 180 mg

Celsius: 200 mg

That is a difference of 20 mg, meaning Celsius contains about 11% more caffeine than Bloom’s 180-mg serving.

Caffeine winner: Celsius

The difference is relatively small compared with the much larger differences you see between some energy drinks.

Bloom’s caffeine comes from green coffee bean extract, while Celsius says caffeine in its products is sourced in part from guarana extract. (Bloom Nutrition)

The source of caffeine does not change the labeled total caffeine amount.

---

Bloom vs Celsius: Sugar

Both standard products are zero sugar.

Bloom’s Sparkling Energy is described as zero sugar. (Bloom Nutrition)

Celsius also states that its energy drinks contain no sugar. (CELSIUS)

Sugar winner: Tie

Neither standard product has an advantage if your specific goal is avoiding sugar.

That does not mean they are identical products. Their caffeine amounts and other ingredients differ.

---

Bloom vs Celsius: Calories

Both standard products contain approximately 10 calories per serving.

Bloom lists 10 calories for its Sparkling Energy cans. (Bloom Nutrition)

Celsius product information also lists 10 calories for the standard energy drink formulation. (CELSIUS)

Calorie winner: Tie

There is no meaningful calorie difference between these specific products.

---

Bloom vs Celsius: Ingredients

This is where the formulas become more distinctive.

Bloom’s Sparkling Energy page highlights:

• Green coffee bean extract
• L-theanine
• Ginseng
• Prebiotics
• Lychee

Bloom says its caffeine comes from green coffee bean extract. (Bloom Nutrition)

Celsius describes its standard energy drink around ingredients including:

• Caffeine
• Green tea extract
• Guarana
• Taurine
• Ginger root extract
• Vitamins

(CELSIUS)

Ingredient winner: No universal winner

The formulas are different, but a longer or different ingredient list does not by itself establish that one drink is healthier or more effective.

---

Bloom vs Celsius: L-Theanine

Bloom’s current Sparkling Energy formula includes L-theanine and ginseng. Bloom describes those ingredients as supporting cognitive function and calm. (Bloom Nutrition)

That tells us the ingredient is present.

It does not establish that Bloom will necessarily produce smoother energy or fewer jitters for every person.

L-theanine: Bloom

Bloom has the ingredient in the standard Sparkling Energy formulation compared here.

---

Bloom vs Celsius: Green Tea and Guarana

Celsius’s formula includes green tea extract and guarana. Celsius identifies caffeine from guarana as part of its formulation. (CELSIUS)

Bloom’s current Sparkling Energy page instead identifies green coffee bean extract as the caffeine source. (Bloom Nutrition)

These are formulation differences rather than proof that one drink is universally superior.

---

Bloom vs Celsius: Caffeine Concentration

The exact can sizes matter, and Bloom currently sells multiple can sizes.

Bloom’s main Sparkling Energy page lists 180 mg caffeine, while its 7.5-oz cans contain 100 mg. (Bloom Nutrition)

Standard Celsius contains 200 mg per can. (CELSIUS)

So the safest comparison is simply:

Bloom standard Sparkling Energy: 180 mg

Celsius standard: 200 mg

Always check the can because product size and formulation can change the comparison.

---

Bloom vs Celsius for Workouts

Both brands position their products around active lifestyles.

Celsius specifically markets its standard energy drinks for use around exercise and publishes research concerning its formula and exercise. (CELSIUS)

Bloom’s Sparkling Energy is marketed as an energy drink and includes caffeine, L-theanine and ginseng. (Bloom Nutrition)

Recommendation

Choose based on the formulation and caffeine amount you want.

Celsius provides 200 mg caffeine, while Bloom provides 180 mg in the standard Sparkling Energy formulation.

Neither fact by itself establishes a universal workout winner.

---

Bloom vs Celsius for Studying

For the standard products:

Bloom: 180 mg caffeine

Celsius: 200 mg caffeine

So Celsius provides the larger caffeine dose.

But caffeine amount alone does not establish that Celsius will improve concentration more than Bloom for every person.

Recommendation

Celsius is the higher-caffeine option; Bloom is the slightly lower-caffeine option.

Choose according to the caffeine amount you actually want rather than assuming more is automatically better.

---

Bloom vs Celsius for Work

The same distinction applies to work.

Bloom provides 180 mg caffeine in its standard Sparkling Energy product. Celsius provides 200 mg per standard can. (Bloom Nutrition)

Recommendation

Bloom may be the better fit if you want slightly less caffeine.

Celsius may be the better fit if you specifically want the higher 200-mg serving.

Those are use-case recommendations, not claims of superior work performance.

---

Bloom vs Celsius for Zero Sugar

Both are zero-sugar products.

Winner: Tie

Bloom says its Sparkling Energy contains zero sugar, and Celsius says its energy drinks contain no sugar. (Bloom Nutrition)

So sugar does not separate these two standard products.

---

Bloom vs Celsius: Taste

Taste is subjective.

Bloom offers flavors such as Summer Splash, Crisp Apple, Strawberry Watermelon, Shirley Temple, Raspberry Lemon and Peach Mango. (Bloom Nutrition)

Celsius also offers a broad flavor selection across its product lines. (CELSIUS)

Without a controlled blind taste test, there is no factual basis for declaring one universally better tasting.

Taste winner: Personal preference

The best approach is to compare the exact flavors you are considering.

---

Bloom vs Celsius: Product Lines Matter

This is one of the most important details in the comparison.

Celsius currently has several product lines:

• CELSIUS / CELSIUS Vibe: 200 mg caffeine
• CELSIUS Essentials: 270 mg
• CELSIUS On-The-Go: 200 mg
• CELSIUS Hydration: 0 mg caffeine

(CELSIUS)

Bloom also has multiple energy formats, including Sparkling Energy and Energy Sticks. Bloom’s current Energy Sticks list 180 mg natural caffeine and zero sugar. (Bloom Nutrition)

So “Bloom vs Celsius” is not one fixed label comparison.

---

Bloom vs Celsius: Caffeine and Safety

The standard products compared here contain substantial caffeine:

Bloom: 180 mg

Celsius: 200 mg

Celsius advises consumers who are new to its energy drinks to consume no more than one CELSIUS product in 24 hours and notes that individual sensitivity varies. (CELSIUS)

Celsius also states that its energy drinks are not recommended for children under 18 or for people who are pregnant or nursing. (CELSIUS)

Your total daily caffeine intake includes coffee, tea, soda, supplements and other caffeinated products.

---

Bloom vs Celsius: Which Is Healthier?

There is no useful universal answer to “healthier” without defining the criterion.

For the standard products compared here:

Both are zero sugar.

Both provide about 10 calories.

Celsius provides slightly more caffeine.

Bloom contains L-theanine and ginseng in its Sparkling Energy formulation.

Celsius uses a different formulation that includes green tea and guarana among its highlighted ingredients.

(Bloom Nutrition)

So the meaningful question is which formulation better fits your preferences and caffeine needs.

Final Verdict: Bloom vs Celsius

Bloom and Celsius are close on several basic nutrition points, but they are not identical.

For the standard products compared here:

Bloom Sparkling Energy provides 180 mg caffeine, zero sugar and 10 calories. (Bloom Nutrition)

Standard CELSIUS provides 200 mg caffeine, zero sugar and about 10 calories. (CELSIUS)

The biggest differences are in the caffeine amount and ingredient formulation.

Choose Bloom if you want the slightly lower 180-mg caffeine serving and its formulation containing L-theanine and ginseng.

Choose Celsius if you want 200 mg caffeine and prefer its formulation featuring ingredients such as green tea and guarana.

Choose either based on flavor if taste is your main concern.

Neither product should be described as universally healthier or more effective simply because of its ingredient list.

The most accurate comparison is the exact product, caffeine amount, sugar, calories, ingredients and your reason for drinking it.
