How much caffeine is in Bloom? A 12 oz can of Bloom Sparkling Energy has 180mg of caffeine from green coffee bean extract, according to Bloom's product page. Bloom's smaller 7.5 oz cans have 100mg. So is 180mg of caffeine a lot? For most healthy adults it is a moderate amount, a bit less than two cups of coffee, but how it feels depends on your body.
Here is a clear breakdown of Bloom's caffeine, what 180mg is equal to, and how to tell if it is the right amount for you.
Bloom Energy Caffeine Content
According to Bloom's published info:
| Bloom product | Caffeine |
|---|---|
| Bloom Sparkling Energy, 12 oz can | 180mg |
| Bloom Sparkling Energy, 7.5 oz can | 100mg |
The caffeine comes from green coffee bean extract. Bloom also sells powders and other products with different amounts, so check the label of whatever you are drinking.
Is 180mg of Caffeine a Lot?
Here is what 180mg is equivalent to:
- Coffee: An 8 oz cup of brewed coffee has about 80 to 100mg, per the FDA. So 180mg is close to two cups.
- Daily guideline: The FDA cites 400mg a day as generally safe for most healthy adults. 180mg is a little under half of that.
- Single dose: The European Food Safety Authority considers single doses up to about 200mg safe for healthy adults. 180mg sits just under that line.
So 180mg is not extreme. But it is still a big dose to get from one can in a few minutes, and for some people it is more than they want.
How Does Bloom Compare to Other Energy Drinks?
Based on each brand's published info:
| Drink | Caffeine |
|---|---|
| Celsius (12 oz) | 200mg |
| Alani Nu (12 oz) | 200mg |
| Bloom Sparkling Energy (12 oz) | 180mg |
| Starbucks Energy Refresher (grande) | 125mg |
| Huxley (12 oz) | 90mg |
Bloom sits slightly below Celsius and Alani Nu, but all three are in the same range: roughly two cups of coffee per can.
Why 180mg Feels Different for Everyone
Your liver clears caffeine mostly through an enzyme called CYP1A2, and how quickly it works varies a lot between people, partly because of genetics. The average caffeine half-life is about five hours, but some people clear it much faster and others much slower. Pregnancy and hormonal birth control slow it down. Smoking speeds it up.
That means a 180mg Bloom can feel like a pleasant lift for one person and leave another person restless at bedtime. Same can, different body.
The amount in a can is the brand's choice. It is not a measure of how much caffeine you need.
Signs 180mg Is Too Much for You
After a can, notice whether you have:
- A racing or pounding heart
- A restless, on-edge feeling
- An upset stomach
- Trouble sleeping, even from an afternoon can
If so, try going smaller. If you are pregnant, under 18, or have a heart condition, anxiety, or a medication that interacts with caffeine, talk with your doctor first. For more context, read Is 200mg of Caffeine a Lot?
How to Find the Right Amount
- Start lower. Many people find 75 to 100mg is plenty. The European Food Safety Authority found about 75mg is enough to increase alertness.
- Mind the clock. With a five-hour average half-life, a 180mg can at 3pm can still leave about 90mg in your system around 8pm.
- Count everything. Morning coffee plus a 180mg can is close to 300mg before dinner.
- Trust how you feel. Your body's reaction is the best guide.
Huxley: Half the Caffeine
If you love a bright, fruity can but 180mg feels like too much, Huxley is a lighter option. It is an Energy Refresher with 90mg of caffeine from Cascara Superfruit, the upcycled fruit surrounding the coffee bean. That is half of a 12 oz Bloom.
Every can also has 50mg of L-theanine for smooth, balanced energy, real fruit juice in Mango, Strawberry, Tangerine, and Peach, 5g of organic cane sugar with no artificial sweeteners, and 100mg of electrolytes.

The Bottom Line
A 12 oz Bloom Sparkling Energy has 180mg of caffeine, close to two cups of coffee, and the 7.5 oz can has 100mg. Whether that is right for you depends on how your body handles caffeine. If a can leaves you on edge, that is a sign to go lower.
When you want a lift that fits your day, try Huxley. In a world of too much, Huxley is just enough.
