Cautions
- 320 mg sodium per tab is a relatively high single-serving dose; account for it if combining with other sodium sources.
- Sweetened partly with xylitol; those sensitive to sugar alcohols may notice digestive effects.
- A Strawberry Hibiscus flavor in this line contains caffeine — check the flavor before choosing if avoiding stimulants.

Product details
Where this label sits
GU Energy Hydration Drink Tabs is one of the hydration mixes in the Scoop Sense database. Every active ingredient on the panel is listed with its own dose — nothing is hidden inside a blend total. It runs 12 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 · 320 mg. Sodium is the main electrolyte lost in sweat and is studied for its role in fluid balance and hydration during exercise.
- Potassium · 55 mg. Potassium works alongside sodium to support normal fluid balance and muscle function.
Flavors & sweetener
Six flavors including one caffeinated option; sweetened with stevia, xylitol, and a small amount of cane sugar.
Who it's best for
Everyday training and moderate sweat losses — a middling sodium load. 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 litre677 mg
At or above the studied amount0studied range 300 mg–700 mg2000 mg
320 mg per serving mixed into 473 ml is about 677 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.

Common questions about GU Energy Hydration Drink Tabs
How much sodium is in GU Energy Hydration Drink Tabs?
320 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.
Does GU Energy Hydration Drink Tabs disclose every dose?
Yes — the label lists an individual amount for each ingredient, with no proprietary blends. That is what the "label fully disclosed" tag on Scoop Sense means, and it is what lets each dose be compared against the amounts used in published research.
