Adrenal Fatigue
By FormBlends Medical Team · Last reviewed April 2026
Adrenal fatigue describes a pattern of HPA axis dysfunction in which prolonged stress leads to dysregulated cortisol output, resulting in fatigue, poor stress tolerance, and hormonal imbalance. While not recognized as a formal medical diagnosis by all endocrinology organizations, the underlying HPA axis dysfunction and its symptoms are well-documented in clinical practice. Treatment focuses on restoring normal cortisol rhythms and supporting the stress response system.

Treatment Options
Lifestyle and Stress Management
Structured stress reduction including meditation, breathwork, reduced training intensity, and deliberate rest periods are the primary intervention for HPA axis recovery.
Adaptogenic Support
Adaptogens such as ashwagandha, rhodiola, and phosphatidylserine have clinical evidence for modulating cortisol and supporting adrenal recovery.
Peptide Therapy Support
Selank has anxiolytic properties that can help modulate the stress response, potentially supporting the normalization of HPA axis function during recovery.
