Evidence Level
Moderate
3 Clinical Trials
8 Documented Benefits
3/5 Evidence Score

EverZen™ is Nutrition21's patent-pending plant-based ingredient — standardized to 6-methoxy-2-benzoxazolinone (6-MBOA), a bioactive extracted from young non-GMO corn (Zea mays) leaves. In plants, 6-MBOA protects against insect, fungal, and bacterial stress. In humans, it works through a dual-action approach: boosting production of key neurochemicals facilitating positive mood and enhancing brain receptors promoting relaxation — helping stabilize cortisol. Backed by clinical studies demonstrating stress and mood benefits. Light 250 mg dose with neutral taste fits powders, capsules, gummies, chewables. Nutrition21's first plant-based ingredient in their portfolio.

Studied Dose 250 mg/day.
Active Compound Corn (Zea mays) leaf extract standardized to 6-methoxy-2-benzoxazolinone (6-MBOA).

Benefits

Cortisol stabilization (stress hormone modulation)

Clinical studies on EverZen demonstrate ability to stabilize cortisol levels — the body's primary stress hormone. Chronically elevated cortisol drives multiple health problems including weight gain, sleep disruption, and cardiovascular issues. Cortisol modulation supports consumers feeling mentally balanced, resilient, and at ease vs reactive to daily stressors.

Mood enhancement via neurochemical production

EverZen's unique mechanism involves boosting production of key neurochemicals that facilitate positive mood. Distinct from suppressive anti-anxiety mechanisms — addresses mood by supporting the brain's own positive neurochemistry. The mood-enhancing benefits complement stress reduction for comprehensive emotional wellness applications.

Relaxation via brain receptor enhancement

EverZen enhances brain receptors that promote relaxation — supporting calm without sedation. The receptor-enhancing mechanism works synergistically with neurochemical production effects. Dual-action approach addresses both the upstream (neurochemicals) and downstream (receptors) of mood and stress pathways.

Healthy stress response (not suppression)

Clinically shown to promote a healthy stress response — supporting appropriate cortisol activity when needed while preventing chronic over-activation. The adaptive positioning distinguishes from sedatives that suppress all stress response. Supports occasional anxiety management without affecting daytime function or alertness.

4-week clinical onset

EverZen has been proven to reduce stress via cortisol modulation, boost mood, and diminish anxiety within 4 weeks. Fast onset for an emotional wellness ingredient — many botanical stress supplements require 8-12 weeks for measurable effects. Practical for consumers seeking noticeable benefits within reasonable timeframe.

Light 250 mg dose with neutral taste

Light 250 mg/day dose with neutral taste fits a broad range of dosage forms — powders, capsules, gummies, chewables. Distinguishes from bitter or high-dose alternatives requiring large capsules or unpalatable flavors. Supports formulation flexibility for consumer-facing applications.

Plant-based natural defense compound

6-MBOA is the plant's natural defense compound — protecting young corn plants from insect, fungal, and bacterial stressors. The natural defense origin aligns with the stress response application in humans. Sourced from non-GMO corn — addressing consumer preferences for clean-label plant-based ingredients.

Two-clinical-study evidence base

EverZen is backed by clinical studies demonstrating stress and mood benefits including improved mood, better stress balance, healthy stress response, effects on relaxation and calming, and support for occasional anxiety. Part of Nutrition21's 100+ studies portfolio.

Mechanism of action

1

6-MBOA neurochemical production support

6-methoxy-2-benzoxazolinone (6-MBOA) supports the brain's production of key neurochemicals associated with positive mood. Mechanism is upstream — addressing the production rather than just receptor activation. The novel plant bioactive class is structurally distinct from common adaptogens or amino acid precursors.

2

Brain receptor enhancement

6-MBOA enhances brain receptors that promote relaxation — supporting calm without sedation. The receptor enhancement mechanism likely involves modulation of GABAergic, serotonergic, or related calming neural pathways. Multi-target mechanism explains the broad stress and mood applications.

3

HPA axis modulation (cortisol regulation)

EverZen modulates the hypothalamic-pituitary-adrenal (HPA) axis — the central stress response system. Cortisol stabilization (rather than suppression) supports healthy stress responses. Mechanism class shared with established adaptogens but via different specific compound.

4

Dual-action approach

EverZen's unique mechanism combines neurochemical production and receptor enhancement — addressing both the upstream and downstream of mood/stress pathways. The dual mechanism distinguishes from single-target alternatives that only address one aspect of stress and mood biology.

5

Plant defense compound bioactivity

6-MBOA is the plant's natural defense compound — protecting against environmental stressors. The molecular bioactivity translates to human applications via the conserved stress response machinery. Plant-derived stress compounds have shown broad applications across multiple species.
