The original formulation of our most popular supplement. Seriphos™ provides superior adrenal support and is intended to calm anxiety and help with stress management.* The benefits of being less stressed and less anxious often include a better and more restful night’s sleep and improved overall quality of life.

Stress affects the body in a number of ways, both positively and negatively. Exposure to chronic stress at any level and regardless of the type of stress is considered negative stress. Chronic stress may adversely affect your health by elevating your cortisol levels beyond what is necessary. This can leave you feeling stressed and feeling overwhelmed as your body’s fight or flight response is triggered at improper times, often before bed. Seriphos works by helping to lower cortisol levels when they are elevated, helping to reduce the effects of negative stress.*

Seriphos is formulated to promote healthy cortisol output during times of chronic and acute stress which may help reduce the effects of adrenal fatigue.* Elevated cortisol levels can lead to other significant health problems including adrenal fatigue. Adrenal fatigue may occur when the adrenal glands are asked to work overtime and the adrenal system is pushed beyond its limits. 

Seriphos helps improve your quality of life by promoting healthy adrenal function and helping your body respond better to stress.* Seriphos is intended to support your adrenal glands. It provides your body with the building blocks it needs to make its own phosphatidylserine and phosphatidylethanolamine. These two nutrients are key components of the cell membrane and help regulate essential aspects of cellular function.

This really works!

I have been a terrible sleeper for as long as I can remember. Can fall asleep but can't stay asleep for more than an hour or so at a time. Sometimes I have to read or lie there in a panic. I've tried all kinds of supplements, warm beverages, music, meditation, new pillows, you name it. Seriphos has worked amazingly for me! I still might wake up in the middle of the night once or twice, but I can fall right back to sleep with no problems. HIGHLY recommended!

Love it

Been using Seriphos for 6 years now. Works great for high cortisol and HPA axis dysfunction


I have been using this product 25 years for my illness Chronic Fatigue Syndrome and Adrenal exhaustion when I have flares of insomnia and high cortisol at night. It helps regulate the high cortisol at night. I cannot do without this product with my illness.

My daughter and I use this for anxiety. It helps control cortisol attacks I call them. When my adrenals are burned out and I get anxiety attacks every early morning it affects your life. Seriphos helps control the worst symptoms.
