Evidence-Based Benefits

  • Stress resilience — ashwagandha (300-600mg KSM-66) reduced cortisol by 23% and perceived stress by 44% in a meta-analysis of 5 RCTs (Lopresti et al., 2019)
  • Anti-fatigue — rhodiola rosea (200-400mg SHR-5 extract) reduced stress-related fatigue in multiple RCTs (Olsson et al., 2009)
  • Cortisol modulation — phosphatidylserine (400-800mg) blunted cortisol response to acute stress in controlled studies (Hellhammer et al., 2004)
  • Nutrient repletion — chronic stress depletes vitamin C (adrenals contain the highest concentration in the body) and B vitamins, particularly B5 (pantothenic acid)

What the Research Says

While "adrenal fatigue" is not recognized by mainstream endocrinology, HPA axis dysregulation from chronic stress is a well-documented phenomenon. Individual ingredients commonly found in adrenal support formulas have varying levels of evidence. Ashwagandha has the strongest evidence (meta-analyses showing cortisol reduction), followed by rhodiola rosea (multiple RCTs for stress-related fatigue). Phosphatidylserine has moderate evidence for blunting the cortisol response. Vitamin C and B vitamins are essential cofactors in adrenal steroidogenesis. Adrenal glandular extracts lack rigorous clinical trial data.
