What's in SWÆT Protein Water
SWÆT is five ingredients. Whey protein isolate, citric acid, nature-identical flavour, monk fruit and sodium benzoate. That's the whole list. Below is what each one is, why it's in the bottle, and the full nutrition panel exactly as it appears on the label.
If a protein drink needs a paragraph of ingredients, ask why.
The five ingredients
| Ingredient | What it is | Why it's in there |
|---|---|---|
| Whey protein isolate | Milk protein, filtered until almost everything that isn't protein is gone | The point of the drink. 24g of it, and it's what lets SWÆT be clear instead of milky. |
| Citric acid | Acidity regulator, the acid in citrus fruit | Holds the pH where whey stays dissolved and clear, and gives the drink its crispness. Without it you'd get cloudy, flat protein water. |
| Nature-identical flavour | Flavour compounds molecularly identical to the ones in the fruit | Makes Mango taste like mango. "Nature-identical" means the same molecule as nature's, made in a lab rather than extracted. |
| Monk fruit | Non-caloric sweetener from Siraitia grosvenorii | Sweetness with no sugar and no calories. It's why the panel reads 0g added sugar and 96.44 kcal rather than 200+. |
| Sodium benzoate | Preservative | Keeps a shelf-stable bottle safe to drink. See below: we'd rather explain it than bury it. |
Nutrition, per 500ml bottle
Straight off the FSSAI label. Note these are per bottle, not per 100ml; the per-100ml convention makes drinks look lighter than they are.
| Per 500ml bottle | Amount | % RDA |
|---|---|---|
| Energy | 96.44 kcal | 4.8% |
| Protein | 24g | 44.44% |
| Total carbohydrate | 0.11g | n/a |
| of which added sugar | 0g | n/a |
| Total fat | 0g | n/a |
| Sodium | 275mg | 13.75% |
We write the calorie figure as 96* in our marketing, and the asterisk always points here: 96.44 kcal. It's a little over 96, and we'd rather show the decimal than round to a number that flatters us.
Why whey isolate and not concentrate
Whey comes in two common grades. Concentrate is cheaper and still carries fat and lactose; it's what makes a shake opaque, thick and chalky. Isolate is filtered much further, so what's left is nearly all protein.
Isolate costs more. We use it because it's the only way to get 24g of protein into a clear drink with 0g fat and trace lactose. A protein water made with concentrate would be cloudy, heavier, and harder on anyone lactose-sensitive.
Why monk fruit and not sugar or sucralose
Monk fruit is a small melon whose sweetness comes from compounds called mogrosides. They're intensely sweet and carry no calories, so a tiny amount does the job.
Sugar was never an option: it would put the bottle north of 200 kcal and defeat the point. We went with monk fruit over synthetic sweeteners because it's plant-derived and doesn't leave the metallic finish some sweeteners do. It's also why the carbohydrate line reads 0.11g.
About the sodium benzoate
Here's the honest version, because this is the ingredient people email us about.
Sodium benzoate is a preservative. It's in the bottle because SWÆT is shelf-stable; it sits in a warehouse, on a truck, in a shop, and in your fridge, and it has to still be safe when you open it. It's approved by the FSSAI and used across the beverage industry, and it works particularly well in acidic drinks like this one.
Could we drop it? Only by making SWÆT a chilled-chain product with a short life, which would mean a more expensive bottle, a smaller delivery radius and a lot of waste. We decided a clean label was worth less than a product that reaches you safely. If a preservative is a dealbreaker for you, we'd rather tell you now than have you find out from the panel.
What's not in it
- No added sugar: 0g, and 0.11g total carbohydrate.
- No fat: 0g.
- No artificial colours. The colour you see is the drink.
- No gums or thickeners. Protein water shouldn't need body added back to it.
- No caffeine, no BCAA blends, no proprietary complexes. Just protein.
Allergens
Contains milk. May contain soy and nuts.
Whey is a milk protein: filtering makes it purer, not dairy-free. Two distinctions worth being clear about:
- Lactose sensitivity: isolate carries only trace lactose, so most lactose-sensitive people are comfortable with SWÆT.
- Milk allergy: this is a reaction to the milk protein itself. SWÆT is not suitable for you. No amount of filtering changes that.
SWÆT is vegetarian (green mark) and is not vegan.
Frequently asked questions
Is nature-identical flavour artificial?
It sits in between. The molecule is identical to the one in the fruit; it's synthesised rather than extracted. It isn't a "natural flavour" under strict definitions, and it isn't an invented artificial one either. We use the term the label uses rather than a friendlier one.
Is monk fruit safe?
Yes. Monk fruit extract has held FDA GRAS (Generally Recognized As Safe) status since 2010 and has been used in China for centuries. It's non-caloric and doesn't raise blood sugar, which is why it suits a zero-added-sugar drink.
Does SWÆT have any hidden ingredients?
No. The five on this page are the five in the bottle, and they match the label exactly. If we ever change the formula, this page changes with it.
Why is there sodium benzoate in SWÆT?
It's a preservative, and it's there because SWÆT is shelf-stable; it sits in a warehouse, on a truck and in your fridge, and has to still be safe when you open it. It's FSSAI approved and works well in acidic drinks. Removing it would mean a chilled-chain product with a short life.
Why is there sodium in SWÆT?
275mg per bottle, about 13.75% of a day's reference. Some occurs naturally in whey and some comes from the sodium benzoate. It's also not useless in a drink you might have after sweating.
Is the SWÆT formula the same in all three flavors?
Yes. Mango, Blueberry and Bubblegum differ only in the flavour compound. Identical protein, calories, and everything else on the panel.
