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.

I have been taking Seriphos for quite a few years. My family physician suggested I take it a very long time ago. I will continue per his suggestion.

Great product

I feel so much better since starting this medication. It has brought down my cortisol levels, and I am feeling so much better. I highly recommend it for anyone struggling with high cortisol.

Will Never Be Without It!

I've been using Seriphos for a little over a year, and can honestly say it's changed my life.

I'm a Senior with long Covid and Afib, who is extremely sensitive to cortisol. Have been all my life. But excess cortisol makes my two conditions far worse than they need to be.

Within an hour of taking Seriphos (on an empty stomach), my hand jitters from LC disappears, and my pulse slows and steadies dramatically. It's like flipping a switch.

And on days I weight-lift, I take it before I go, which has definitely helped my muscle growth and ability to work harder.

Long story short: I will never be without Seriphos - the only supplement that actually works.


What a magical product.
No more stress, instead more restful night's sleep.
