Daily immune builder for safe, strong immune support.* Formulated by Dr. James L. Wilson.

Stress and Immune Function:

Adrenal stress hormones like adrenaline and cortisol trigger important changes in your immune function because they have the ability to regulate every immune cell in your body. The acute “fight or flight” stress responses set off by adrenaline temporarily increases certain aspects of innate, front-line immunity. Although a certain amount of cortisol is necessary to stimulate proper immune function, the elevated cortisol accompanying stress partially suppresses the deeper, adaptive aspects of immunity.

If you are facing a lion, your body will quickly shift its energy resources from less immediate threats to help you survive the critical danger in front of you. If stress continues, your adrenals eventually may not be able to keep up with the continued demand (adrenal fatigue) and start producing too little cortisol to help stimulate optimal immune function.

Managing stress, supporting adrenal glands and promoting strong immune function can significantly support your ability to stay well.*
