Clear whey drinks, decoded: the RTD wave’s missing number

By Aali Qureshi, founder of Deadly Company · Published October 24, 2026 · Updated October 31, 2026

Short answer: Clear whey drinks like juice, but none of the nine clear drinks checked in October 2026 publishes an essential amino acid total. Derived from whey isolate’s profile, a 20g clear serving carries roughly 8.8g of EAAs and 2.1g of leucine, under the ~2.5–3g trigger. Muscle Water Aminos serves 16g of EAAs with 4g of leucine and 3.5g of creatine, for readers who want the light format without an under-trigger serving.

> Key takeaways > – The number that decides what a serving does — EAAs per serving — appears on none of the clear labels we checked. Only the biggest number, protein grams, is printed. > – A 20g clear whey serving is about 8.8g of EAAs and ~2.1g of leucine: under the muscle-building trigger, not at it. > – The best in the set, Oath, publishes 2.7g of leucine — on its website, not its label — which reaches the trigger’s middle with no margin, inside protein that still has to be digested. Creatine is 0g in every clear drink and RTD we checked, all nine of them. > – Clear whey genuinely beats the shake on texture and lightness. We concede the vehicle. The cargo is the argument.

The first protein drink that didn’t feel like punishment

Give the category its due. Clear whey felt like freedom.

After years of chalky shakes that sat in the stomach like wet cement, here was protein that poured like lemonade, drank cold, and left you feeling like a person instead of a patient. People didn’t just buy it. They felt rescued by it.

I understand that feeling. I built Muscle Water Aminos around the same belief: format is destiny.

Which is exactly why the label deserves a harder look. A drink can fix everything about the experience and nothing about the maths — and the maths is where muscle lives.

The missing number

Flip any clear whey label around and you will find protein grams in large type. What you will not find, on any of the nine clear drinks and RTDs in our October 2026 teardown, is an EAA total. Not one.

That is the single most decision-relevant number a protein drink can carry — how many of the nine building blocks your body cannot make — and it is absent from the entire category.

You can derive it, because whey isolate’s amino-acid profile is published science: about 44% of it is essential amino acids (Gorissen et al., 2018). The full whey profile the derivation comes from is worked through in Whey protein, decoded. So a 20g clear serving — Myprotein Clear, Isopure Infusions, Oath, all built on 20g of whey isolate — delivers roughly 8.8g of EAAs. Our 16g EAA serving delivers the whole ~138g steak’s worth. Leucine, the amino acid that switches muscle building on, derives to about 2.1g in that clear serving — below the ~2.5–3g trigger, before digestion takes its share.

Leucine is the ignition. The other EAAs are the bricks. A serving under the trigger has bricks and no ignition. Below the trigger, it’s flavoured water.

The teardown, checked 18 October 2026 — published on the label, and derived from the whey profile

Drink	Protein per serving	EAA total published	Derived EAAs	Leucine	Creatine
Myprotein Clear	20g	Not published	~8.8g	~2.1g, derived	0g
Isopure Infusions	20g	Not published	~8.8g	~2.1g, derived	0g
Oath	20g	Not published	~8.8g	2.7g, published on the brand’s website, not its label	0g
Bucked Up Protein Soda	25g	Not published	~11g	~2.6g, derived	0g

Read the third column as the set-wide finding, not just a row for these four: across all nine drinks and RTDs checked, not one publishes an EAA total, and creatine is 0g in all nine.

The exceptions prove the design point. Oath, the most transparent brand in the set, publishes that 2.7g of leucine on its website Q&A, not the facts panel — reaching the trigger’s middle with zero margin, still inside intact protein. Bucked Up’s protein soda puts 25g of whey in a can, deriving to ~11g of EAAs and ~2.6g of leucine, at $3.67–$5.00 a can (prices checked October 2026).

The 4g of leucine in Muscle Water Aminos is formulated to clear the leucine trigger with a 1.3g margin, with 3.5g of creatine in the same glass. That creatine, translated, is roughly the creatine in ~2 lb of raw beef.

“So I’ll drink two” — the maths of the workaround

You can clear the trigger with clear whey. Drink two servings back-to-back and the leucine adds up.

Now price the workaround. Two clear servings are ~17.6g of EAAs — genuinely more than our 16g, said fairly — at double the servings, double the tart acid load the format is known for, roughly 160–180 calories across the pair, and, at soda prices, $7–$10 a day for the habit.

Spread the two servings across the day instead, the way people actually drink them, and each one is its own feeding. Each one under the trigger again. The trigger is per feeding, not per day.

A product designed around that fact looks like one small serving that clears it alone. That product is not a clear whey.

Clear in the glass, intact in the gut

The lightness is real. The digestion is still intact-protein digestion: the chain must be cut apart before its aminos reach the blood, peaking around 60–90 minutes against ~30 for free-form EAAs. On a GLP-1-slowed stomach, longer.

None of this makes clear whey a bad product. It makes it a shake wearing a better outfit, taxed like a shake where it counts.

Our own drinkability rules are stricter still: no artificial sweeteners and no stevia — allulose, monk fruit, cane sugar and thaumatin do our sweetening — a serving that mixes into water, another drink, or a smoothie, and nothing to digest before the aminos are available.

Muscle Water Aminos is a protein supplement, not a meal replacement. Food first — this covers the protein on the days food isn’t happening.

Where clear whey honestly wins

Taste and texture, for a lot of people, full stop. It is the first protein format many shake-quitters actually finish, and finishing any protein beats abandoning a better-on-paper tub.

It is lighter than a shake. It travels. Per serving it is fairly priced, at ~$2 a serving on the powders we checked.

If you drink it, enjoy it, and hit your daily protein from food alongside, it is doing its job. The argument is only this: if the serving is your muscle strategy — on a GLP-1, at 55, on the days food isn’t happening — a serving that never reaches the trigger is a strategy with a hole in the middle of it.

The bottom line

Clear whey solved the shake’s texture and kept the shake’s unit.

Measured in the units muscle reads, the standard clear serving delivers about half the EAAs of a formulated EAA serving, lands its leucine under the trigger, and carries no creatine — and its label will not tell you any of that, because the EAA number is the one number the category doesn’t print. Ask for it. And if you want the full method for checking the next label anyone hands you, work through How to read an amino acid label: the 6-point scorecard.

Muscle Water Aminos gives readers who want the light format without an under-trigger serving 16g of EAAs, 4g of leucine and 3.5g of creatine in a glass of water — and it helps preserve lean muscle when paired with resistance training and adequate protein.

FAQ

Is clear whey better than regular whey? As a drink, often yes — lighter, colder, easier to finish. As a dose, the servings run smaller (20g vs 25g), so per serving it delivers fewer EAAs (~8.8g vs ~11–12g) and less leucine (~2.1g vs ~2.7g). The format improved; the payload shrank.

Why don’t they print the EAA content? Because 8.8 is a smaller number than 20. Protein grams is the biggest number any label can show, so protein grams is what gets printed. Nothing in labelling law requires an EAA total — which is why we publish ours on the front.

Is one clear drink a day enough to protect muscle on a GLP-1? On its own numbers, no: ~2.1g of leucine does not cross the per-feeding trigger, and the 2025 GLP-1 joint advisory targets 1.2–1.6g of protein per kg of adjusted body weight daily — a total built from feedings that actually switch muscle building on. Food, training, and servings that clear the trigger: that is the whole strategy, and no single drink replaces it. The full routine is set out in The GLP-1 muscle-preservation protocol.

What about the protein sodas? A fun format with a serious price: ~11g of derived EAAs per can at $3.67–$5.00 (October 2026). As an occasional drink, fine. As a twice-a-day muscle habit, the maths — cost, acid, intact digestion — works against it.
