CheckedIs the label honest?
Every ingredient shows its amount · 16 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

The barcode identity checks out · 850070057318.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 850070057318 to "Fire Salt Hydration Sticks" (Fire Science) — consistent with this listing.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
Reviews rose from 24 to 210 between July 16, 2025 and August 13, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 24 to 210 between July 16, 2025 and August 13, 2026. The largest rise inside any single 30-day window was about 44, so the count moved in steps rather than in one burst.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 90 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
0studied 200 mg–420 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
