Inside the Zen study: How participants experienced positive change
At Nutri-Link, we’re known for delivering high-quality supplements trusted by Practitioners and customers alike. Recently, we partnered with Lori, a community that shares real product experiences, to test Allergy Research Group’s Zen with 20 people managing autoimmune and related conditions.
The Study:
- Participants (ages 20–65) took Zen daily for 4 weeks.
- They paused any new supplements or medications for 2 weeks before starting.
- Weekly check-ins tracked changes in wellbeing.
The Results:
Participants reported consistent improvements in:
✅ Overall wellbeing and life satisfaction
✅ Optimism and sense of calm
✅ Emotional balance
✅ Sleep quality and duration
Ad - Zen product was gifted by Nutri-Link to all Lori community members to try & share their individual experiences & honest feedback.
