WHY PEOPLE TAKE CORTISOLZEN

Cortisol AKA the body’s main stress hormone when left unchecked leaves the body in a “fight-or-flight” stress response. 

• High Cortisol Levels: Long-term high stress can lead to weight gain, high blood pressure, sleep problems, and constant tiredness.

• Low Cortisol Levels: Too little cortisol can cause extreme fatigue, muscle weakness, and low blood pressure.

CortisolZen is a purpose built, science backed formula to help combat these issues and balance cortisol levels.

*Survey results from 250 customers who have been taking the product for a minimum of 60 days. Consistency is key.

CortisolZen is gentle, non-habit-forming, and flexible enough to take anytime you need to reset. Most customers reach for it:

After a long workday
Before bed, to unwind
Midday, when stress starts to spike after social or sensory overload

Just pour, mix, and sip your way to a calmer state.
