Product details
Where this label sits
Ultima Replenisher Electrolyte Mix is one of the hydration mixes in the Scoop Sense database. It runs 30 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
- Potassium · 250 mg. Potassium contributes to normal muscle function and fluid balance.
- Magnesium (magnesium citrate) · 100 mg. Magnesium plays a role in normal muscle and nerve function.
- Vitamin C · 100 mg. Vitamin C contributes to normal immune function.
- Sodium · 55 mg. Sodium is studied for its role in fluid balance, though this dose is far below sweat-replacement levels.
Flavors & sweetener
Wide zero-sugar flavor range (Grape, Orange, Raspberry, Watermelon and more) sweetened with organic stevia leaf extract.
Who it's best for
Flavour and light top-ups rather than replacing a real sweat loss — the sodium here is well under the amount hydration research works with. 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 litre116 mg
39% of the low end of the studied range0studied range 300 mg–700 mg2000 mg
55 mg per serving mixed into 473 ml is about 116 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.

The brand's own storefront, read July 2026. A seller's rating is collected and moderated by the seller — treat it as a marketing figure, not an independent one.
What people actually report
Keto and low-carb users like Ultima's taste and use it as a lower-carb Gatorade substitute, but a recurring complaint on r/keto is digestive upset — diarrhea or bloating — that some attribute to the formula.
- positive Taste. Fans specifically call out the raspberry and grape flavors as good, with one saying the tartness helps them drink enough water.
- negative Digestive side effects. Multiple users on r/keto report diarrhea or puffiness/bloating after regular use, though they aren't certain Ultima is the sole cause.
- positive Gatorade substitute. Keto dieters describe switching to it as a substitute for Gatorade to restore electrolytes lost from the diet or workouts.

Common questions about Ultima Replenisher Electrolyte Mix
How much sodium is in Ultima Replenisher Electrolyte Mix?
55 mg per serving, with no 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.
