5 Celsius Alternatives With Less Caffeine (2026 Guide)

Want the head-to-head version? See Josie vs Celsius, label vs label.

Full disclosure before we start: this article is written by Josie, and Josie is one of the five alternatives below. We think it's the best one, obviously. But the other four are real options, and we'll play them straight.

Why you might want less than 200mg

Here's the label math. A can of Celsius contains 200mg of caffeine, listed as caffeine anhydrous, a synthetic form. It's sweetened with sucralose. None of that is a secret. It's printed right on the can. For comparison, an 8oz cup of drip coffee typically has about 95mg of caffeine. So one Celsius is roughly two cups of coffee, consumed in about ninety seconds.

For some people, that's exactly the point. For others, 200mg in one sitting is more than they want, especially after noon. Research on caffeine generally puts its half-life at around five to six hours for most adults, which means a good chunk of a 2pm can is still circulating at 8pm. If you've been doing that math yourself lately, here are five ways to dial it down without quitting caffeine entirely.

The five alternatives

1. A lower-dose caffeinated sparkling water (this is us)

Josie is a sparkling water with 65mg of natural caffeine from green tea, plus Lion's Mane mushroom, Cordyceps mushroom, vitamin B12, and a light touch of plant-derived monk fruit. Zero sugar, zero calories, zero artificial sweeteners. No sucralose, no acesulfame potassium, nothing engineered to taste like candy. The full ingredient list is seven items long, and you can read every one of them on our ingredients page.

The 65mg dose is about what you'd get from a single shot of espresso. Enough to feel awake. Small enough to drink at 3pm and still sleep like a person. Lion's Mane is traditionally used for focus (we wrote a whole post on whether Lion's Mane actually works), and Cordyceps is traditionally used for endurance. It comes in four flavors: Cucumber, Lemon-Lime, Mixed Berry, and Tangerine. It's made in the USA, in Utah, and a 12-pack runs $39.99 at drinkjosie.com, Amazon, or TikTok Shop. BevNet and Yahoo Finance have both covered the brand, so you don't have to take our word for it that we exist.

2. Green tea

The original low-dose option. A cup of green tea typically has about 28mg of caffeine, and it naturally contains L-theanine, an amino acid commonly associated with a calmer kind of alertness. We like it so much we wrote about the L-theanine and green tea combo ourselves. Downsides: it requires hot water, a kettle, and patience, and it tastes like green tea.

3. Yerba mate

A South American holly leaf brewed like tea. A cup typically lands around 70 to 85mg of caffeine, so it's a real step down from 200mg but not a small dose. Canned mate is convenient, but check the label. Many popular versions carry 20 grams of sugar or more per can.

4. Half-caff coffee

Mix regular and decaf beans and an 8oz cup drops to roughly 50mg. You keep the ritual, the mug, the whole morning identity. The catch: you have to make it, and coffee's tannins are what stain teeth over time. A clear liquid like Josie doesn't do that.

5. Caffeinated still water

Flat water with caffeine added, usually somewhere between 30 and 100mg depending on the brand. It works, but most versions are exactly what they sound like: water that happens to have caffeine in it. No bubbles, no flavor to speak of, nothing else in the can.

Side by side

How to choose

• If you love the ritual of brewing something: green tea or half-caff.
• If you want a cold can with zero prep and zero artificial sweeteners: Josie.
• If you're caffeine sensitive: green tea first, then work up.
• If you want caffeine and nothing else at all: caffeinated still water.

The honest answer is that the right alternative depends on how much caffeine you actually want. If 200mg was too much, don't overcorrect to zero. Find the dose that makes you feel awake without making you feel like you drank three coffees on an empty stomach.

FAQ

What has less caffeine than Celsius?

Almost everything. Celsius has 200mg per can. Josie has 65mg from green tea, drip coffee has about 95mg per 8oz cup, brewed yerba mate has roughly 70 to 85mg, half-caff coffee about 50mg, and green tea about 28mg.

Is 200mg of caffeine too much?

It depends on you. Commonly cited guidance for healthy adults is up to around 400mg per day, so one Celsius is half of that in a single can. Caffeine sensitivity varies a lot from person to person, and body size, sleep, and timing all matter.

Is there a natural alternative to Celsius?

Yes. Josie uses 65mg of natural caffeine from green tea instead of synthetic caffeine anhydrous, and it skips artificial sweeteners entirely. It's sparkling water with caffeine, Lion's Mane, Cordyceps, and B12, and nothing else beyond natural flavors.

Want to test the lower dose for yourself? The Josie variety pack has all four flavors, so you can find your favorite before committing to a full case. No sugar. No calories. No weird stuff.
