Product details
Where this label sits
Nuun Sport is one of the hydration mixes in the Scoop Sense database. It runs 10 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- Sodium · 300 mg. Sodium is the main electrolyte lost in sweat and is studied for its role in fluid balance.
- Potassium · 150 mg. Potassium contributes to normal muscle function.
- Magnesium · 25 mg. Magnesium plays a role in normal muscle and nerve function.
Flavors & sweetener
Ten light, fizzy flavors such as Lemon Lime and Tri-Berry, sweetened with stevia and about 1 g of sugar per tablet.
Who it's best for
Everyday training and moderate sweat losses — a middling sodium load. A reasonable pick when cost per serving matters. A sensible first tub — nothing on the panel that catches a new user out. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.

Sodium per litre634 mg
At or above the studied amount0studied range 300 mg–700 mg2000 mg
300 mg per serving mixed into 473 ml is about 634 mg per litre. Sports-nutrition guidance puts sodium somewhere between about 230 and 1100 mg per litre of fluid for sustained sweating, depending on which body is writing — 300–700 mg per litre sits inside every version of it. Higher-sodium mixes are built for heavy sweat losses, not for casual sipping.

What other people say
Why we don't rate productsTwo different things, side by side: the rating the seller publishes on its own store, and what independent users write in public threads. Scoop Sense writes neither and collects no reviews of its own. Neither is evidence that a product works — they describe what people experienced and expected, not what the research shows.

What people actually report
The dominant recent conversation about Nuun isn't taste or effectiveness but the discovery that Nestlé owns the brand, which has pushed some loyal runners to look for substitutes even though most still say they like the product itself.
- negative Nestlé ownership backlash. A highly upvoted thread revealed Nuun is owned by Nestlé, prompting runners who avoid the company to ask for substitutes.
- mixed Still liked despite the news. Several commenters in that thread said they still love using Nuun and may keep buying it even after learning about the acquisition.
- negative Skepticism it does much. At least one commenter on a separate thread dismissed tablets like Nuun as unlikely to meaningfully help hydration compared to just drinking water.

Common questions about Nuun Sport
How much sodium is in Nuun Sport?
300 mg per serving, alongside 1 g of sugar. Sodium is the main electrolyte lost in sweat, but needs vary widely with sweat rate and diet — and daily sodium from food counts toward the same total.
