“Compliant”
Evidence →“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Flyby Electrolytes Powder, No Added Sugar
Checked against public sources on July 30, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The headline amount is not tied to a panel row for the same ingredient. You are being sold on an ingredient the verified panel does not separately declare. The brand should explain the mismatch.
Is the dose real?Panel read — dose not verified4 ingredients listed; no advertised amount we could confirm against them

Is it the real thing?✓Barcode matches outside records
Trouble on record?✓No recalls found
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Public contextIs the label honest?
The headline amount is not tied to a panel row for the same ingredient
You are being sold on an ingredient the verified panel does not separately declare. The brand should explain the mismatch.
Evidence and sources
The listing presents 1,000 mg for potassium, but vision:claude-cli:subscription does not contain a same-name quantified row. The saved image read may be incomplete, so this is a specific question to resolve rather than a contradiction.
Locked evidence record →Open the full source-linked findingCheckedIs the label honest?
Every ingredient shows its amount · 4 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
We can see -6 of this product’s 32 reviews — the count fell between July 19, 2025 and July 25, 2026. That is too small a slice to say anything about the wider pattern.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews fell from 38 to 32 between July 19, 2025 and July 25, 2026. The largest rise inside any single 30-day window was about 4, 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 120 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.
