The clean energy drink checklist, what to look for

"Clean" gets thrown around on cans a lot. It's a marketing word, so it can mean almost anything. What follows is what it actually looks like on a label. Ten things you can check in the grocery aisle in under a minute, no biochemistry degree needed.

Use it on any can. Your favorite, ours, anyone's. The label doesn't lie once you know where to look.

1. Where does the caffeine come from?

Most drinks list caffeine anhydrous, which is usually synthetic caffeine made in a lab. A smaller number use "natural caffeine from green tea" or "green coffee bean extract," which means it was pulled from a plant.

What to look for: a named source like green tea or coffee, not just "caffeine anhydrous" with nothing after it. (More on the difference between natural and synthetic caffeine.)

2. How much caffeine, and is that dose reasonable?

Anywhere from 100mg to 200mg is a solid, everyday range for most people. Some drinks push 200 to 300mg into a single can, which can be a lot for anyone under 175 pounds, sensitive to stimulants, or drinking coffee earlier in the day.

What to look for: a dose that makes sense for you. 400mg total daily caffeine from all sources is the upper end for most healthy adults.

3. What's sweetening it?

The sweetener list tells you almost everything about a "clean" claim. Sucralose, aspartame, and acesulfame potassium are the artificial standbys. Allulose, monk fruit, and stevia are the plant-based alternatives.

What to look for: plant-based sweeteners if you're avoiding artificial. And a drink that isn't loading up multiple sweeteners to mask each one's aftertaste. (Deeper dive on artificial sweeteners and cleaner alternatives.)

4. How much sugar?

0 grams of sugar is common now. If a drink still has sugar, it usually shows up as cane sugar or "juice concentrate."

What to look for: 0g added sugar, especially if you're drinking these regularly.

5. Are actives listed at exact amounts, or hidden in a "blend"?

A "proprietary energy blend" or "focus matrix" on the label means the ingredients inside are grouped together with only the total dose shown. That's a formulation shortcut, and it usually hides tiny doses of expensive ingredients.

What to look for: every active listed with its own name and its own milligram amount. If you can't find the dose, assume it's small.

6. Are the doses actually meaningful?

Even when doses are listed, they can be tiny. 25mg of L-theanine won't do much next to 200mg of caffeine. 200mg of creatine is a tenth of a real everyday dose.

What to look for: doses that match what research typically uses. For a starting point:

• Caffeine: 100 to 200mg per serving is the everyday range.
• L-theanine: 100 to 250mg to noticeably pair with caffeine. (Why the pairing works.)
• Creatine: studies use 3 to 5 grams per day. Two of our cans deliver 4g total. (More on how much creatine you actually need.)

7. Is it third-party tested?

Every batch of any beverage should be tested for heavy metals and contaminants. The best brands make those results available so you can actually see them, not just take their word for it.

What to look for: a QR code on the can, or a public batch-lookup page on the brand's site. If neither exists, ask.

8. How long is the ingredient list?

A shorter list isn't automatically better, but it's usually a signal. Clean formulas tend to run 8 to 15 ingredients. Long lists filled with flavor compounds, gum stabilizers, and preservatives are a hint that the brand is dressing up a thinner formula.

What to look for: a list you can actually read and mostly recognize.

9. Is it naturally flavored?

"Natural flavors" is a broad term, but it's still better than a list of numbered artificial flavors. Some brands go further and name their flavor sources (real fruit, tart cherry extract, etc.), which is even better.

What to look for: naturally flavored on the front, and named sources in the ingredient list where possible.

10. Does it add anything real, or is it just marketing?

A lot of drinks lean on "adaptogens" or "mushroom blends" at doses so tiny they can't do much. That's usually cover for a thin formula.

What to look for: real doses of real ingredients that support what you actually use an energy drink for. For example, creatine, L-theanine, B-vitamins, and electrolytes at meaningful amounts.

How Energy+ scores on this checklist

Since we built this checklist based on what we look for ourselves, here's how our own can lines up:

• Caffeine source: 180mg natural caffeine from green tea.
• Dose: 180mg per can, everyday range.
• Sweeteners: allulose and monk fruit. No sucralose, aspartame, or acesulfame potassium.
• Sugar: 0g.
• Actives: named and dosed at exact amounts. No proprietary blends.
• Meaningful doses: 200mg L-theanine, 2g creatine (Creabev), plus beetroot, L-citrulline, and a B-vitamin complex.
• Third-party tested: yes, every batch. Scan the QR code on the can.
• Ingredient list: short enough to read.
• Naturally flavored: yes, Tart Peach.
• Real vs marketing: creatine, L-theanine, and B-vitamins at real doses, not tiny sprinkles of trend ingredients.

This checklist works on any can. Take it into a store, pick up your usual drink, and see how it scores. If it holds up, great. If it doesn't, you'll know exactly where the gaps are, which makes the switch easier when you're ready to make one.
