Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Waterboy Workout Hydration
Checked against public sources on August 4, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Every ingredient shows its amount · 19 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
“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.

The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed1
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently1
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.
What is worth knowing.
Headlines first. Open evidence only when you want the source trail.

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 findingThe barcode identity checks out · 850038437183.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
The brand's store lists this exact barcode as “Workout Hydration” (variant: Variety Pack) — identity confirmed across retailer listings.
Locked evidence record →Open the full source-linked findingReviews rose from 96 to 139 between July 24, 2025 and July 31, 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 96 to 139 between July 24, 2025 and July 31, 2026. The largest rise inside any single 30-day window was about 8, so the count moved in steps rather than in one burst.

These are evidence gaps, not strikes against the product.
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.
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.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
