Frequently Asked Questions

Is adrenal fatigue a real condition?

The term "adrenal fatigue" is not recognized as a medical diagnosis by the Endocrine Society or mainstream endocrinology. However, HPA axis dysregulation — where chronic stress disrupts the normal cortisol rhythm — is a well-documented phenomenon with real symptoms including fatigue, poor stress tolerance, and sleep disruption. True adrenal insufficiency (Addison's disease) is a serious medical condition requiring prescription cortisol replacement and is diagnosed via ACTH stimulation testing.

What is the best single supplement for adrenal support?

Ashwagandha (KSM-66 extract, 300mg twice daily) has the strongest clinical evidence for supporting healthy cortisol levels and reducing perceived stress. It is backed by multiple RCTs and a meta-analysis. Rhodiola rosea (200-400mg SHR-5 extract) is a strong second choice, particularly for stress-related fatigue and mental performance. For best results, ensure adequate vitamin C, B-complex, and magnesium intake alongside adaptogens.

How long does adrenal support take to work?

Most adaptogens require 4-8 weeks of consistent daily use to show measurable benefits. Some people notice improved energy and stress resilience within 1-2 weeks, while cortisol normalization and HPA axis recalibration may take 2-3 months. Lifestyle factors — sleep, stress management, balanced nutrition — are equally important and should accompany supplementation for optimal results.
