About SleepStack
One supplement. One standard.
Most magnesium articles online repeat the same handful of misframings. The same studies get cited without their actual sample sizes. Specific bioavailability percentages get attributed to papers that don't contain those numbers. Brand reviews fail to disclose industry funding. We built SleepStack to do it better.
What we're building
A supplement worth taking
Single-ingredient magnesium bisglycinate at 275mg elemental per serving. The dose sits in the middle of the range used in clinical sleep research. The form is the one most commonly cited in sleep and anxiety literature. The label math matches the chemistry — no proprietary blends, no undisclosed fillers.
Content worth trusting
Every research claim on SleepStack is traced back to a primary source. Every citation is checked against the actual paper, not a summary. When a finding is mixed, conflicting, or low-quality evidence, we say so plainly. When a paper is industry-funded, we disclose it. When we can't find a citation that supports a popular claim, we don't make the claim.
A corrections culture
Our internal source-verification notes are kept in a public-facing project repository, including which papers have been checked against the original PDF versus only the abstract. Corrections are made via traceable commits with a date and reason. The '80% glycinate / 4% oxide' bioavailability myth — recycled across thousands of supplement articles — is one example of a claim we traced, found unsupported, and removed from every page on the site.
How we handle the science
- Primary-source citations with PMIDs or DOIs — not secondary summaries
- Sample sizes, effect sizes, and p-values disclosed for key claims
- Industry funding disclosed when present in cited studies
- Mixed or null findings reported alongside positive findings
- Claims we can't source are removed, not softened
- All articles carry a 'Sources current as of' date — we don't pretend research stands still
Full sourcing notes, paper-level verification tiers, and our running corrections log are documented on the editorial standards page.
