Jigsaw Health Announces New Human Clinical Study on MagSoothe® Showing Improvements in Sleep Quality and Perceived Stress.
SCOTTSDALE, AZ — April 6, 2026 — Jigsaw Health, a leader in science-backed nutritional supplements, today announced the results of a new 4-week human clinical study evaluating the safety, efficacy, and user experience of Jigsaw MagSoothe®.
The study, conducted in partnership with Heads Up Health and OvationLab, followed adults experiencing poor sleep and used both validated questionnaires and wearable data from Oura Ring devices to assess outcomes.
Key Findings
- 34% reduction in perceived stress*
- 17% improvement in sleep quality*
- Statistically significant improvements across multiple sleep and wellness metrics*
- 82% of participants said they would purchase MagSoothe®
- No serious adverse events reported
“This study confirms what we’ve heard from customers for years,” said Natalie Ochoa, President of Jigsaw Health. “People feel more rested, more calm, and feel better overall when they take MagSoothe®, and now we have real-world data to back it up.”
Study Overview
The study included 65 adults with persistent poor sleep quality over a 4-week period. Participants consumed one packet of MagSoothe® daily while researchers tracked:
- Sleep metrics (total sleep, REM, deep sleep, sleep score)
- Stress and sleep disturbance via validated questionnaires
- Physiological data via Oura Ring (HRV, resting heart rate, respiratory rate)
The combination of subjective and objective data provides a more complete picture of real-world outcomes.
Why This Matters
Sleep issues and daily tension are two of the most common complaints among adults, and most solutions either don’t work or come with tradeoffs.
This study demonstrates that a simple nightly routine of taking MagSoothe® can:
- Support better sleep quality*
- Promote a calm physiological state*
- Help address common magnesium insufficiency*
…all without complex routines or pharmaceutical interventions.
What Makes MagSoothe® Different
MagSoothe® is not just another magnesium supplement.
It’s a highly bioavailable magnesium glycinate powder, designed for:
- Easy nightly use (no pills)
- High compliance (simple, enjoyable routine)
- Targeted support for sleep and relaxation*
And now, backed by human clinical data.
