Protocol development in integrative medicine is not typically a simple process. Individuals require individualized care, and what works for one patient may not work for another.

To establish these protocols, we first developed a Rating Scale that could be used to discern the rigor of evidence supporting a specific nutrient’s therapeutic effect.

The following protocols were developed using only A through C-quality evidence.

A
Systematic review or meta-analysis of human trials
B
RDBPC human trials
2+ studies and/or 1 study with 50 + subjects
C
RDBPC human trials
1 study

Stress impacts adrenal function and may cause fatigue, cognitive impairment, anxiety, and depression. Burnout syndrome is a result of stress and has been receiving more attention as its impact in the medical field has been increasing. In a systematic review of 182 studies, the total estimated rate of burnout among physicians was as high 67.0%. (16) While physicians consistently have higher rates of burnout and stress than the general population, the prevalence of stress in the general population has been increasing as well. In 2020, stress prevalence in response to the global pandemic was cited at 29.6% according to a systematic review and meta-analysis of five studies. (17)

Consistent or prolonged stress to the point of burnout negatively contributes to overall health. Risk of chronic fatigue, cardiovascular disease, and mortality all increase with chronic stress. (12) Stigma around seeking help may prevent some people from reaching out at earlier stages. When surveyed, medical residents most commonly were concerned about negative consequences with their career if they took a medical leave. (5) Actively looking for signs of stress, alleviating them, and preventing further adrenal damage are essential to assisting patients through hard times. Supporting adrenal gland function or modulating stress response through other physiological mechanisms is an important aspect of integrative care for this patient population.

The ingredients presented in the protocol below reflect research findings demonstrating the efficacy of herbs and supplements that might be used to support adrenal function and alleviate stress.

Ashwagandha (Withania somnifera)

240-300 mg, total per day, minimum 8 weeks (2)(13)

  • Serum cortisol, body weight, and body mass index, Perceived Stress Scale and Food Cravings Questionnaire, Oxford Happiness Questionnaire, and Three-Factor Eating Questionnaire were all improved when given 300 mg twice per day (3)
  • High-concentration full-spectrum ashwagandha root extract increased quality of life, decreased serum cortisol, and decreased stress-assessment score compared to placebo in adults with a history of chronic stress (2)
  • HPA-axis function and level of stress improved as shown by decreases in Hamilton Anxiety Rating Scale (HAM-A), morning cortisol levels, and DHEA-S compared to placebo when given 240 mg once daily (13)
  • Systematic review of three studies found withania somnifera effective for treatment in anxiety due to improved scores for anxiety or stress when compared to placebo (15)

Rhodiola (Rhodiola rosea)

400-576 mg, total per day, minimum 28 days (6)(14)

  • Rhodiola increases mental performance including the capacity to concentrate and decreased cortisol response to awakening stress (14
  • Improvement in general fatigue including aspects like physical and mental fatigue, neuro-motoric tests, and overall wellbeing was shown to be significantly improved (4)(18)
  • Standardized extract SHR-5 improved fatigue syndrome from stress burnout demonstrated by improved Pine’s burnout scale score, post-treatment cortisol responses, and ability to concentrate compared to placebo  when given 576 mg per day (14)
  • Rhodiola rosea extract WS® 1375 improved stress, disability, and functional impairment as early as 3 days into treatment compared to placebo in people with life-stress symptoms (6)
  • Healthy physicians working night shifts experienced improved fatigue index score when given standardized extract SHR-5 compared to placebo (4)
  • During examination period, students experienced improved general well-being, mental fatigue, neuro-motoric tests, and physical fitness with supplementation (18)

Asian ginseng (Panax ginseng)

960-2000 mg, total per day, minimum 4 weeks (7)(10)  

  • Numerical rating scale (NRS) score, a self-assessment of fatigue severity, was improved, as well as visual analogue scale (VAS) when given 2000 mg per day (10)
  • Panax has shown to reduce circulating cortisol while increasing enzymatic and nonspecific antioxidant activity in response to physical stress (7)
  • High (960 mg) and low (160 mg) doses of GINST15, enzyme-fermented ginseng, were given and intense resistance exercise work stress was done and compared to placebo; circulating cortisol decreased while enzymatic and nonspecific antioxidant activity increased demonstrating high and low dose to be effective in treating physical stress (7)
  • Systematic review of 10 studies found panax ginseng to be effective for treatment of fatigue with chronic illness with low adverse risks (1)
  • When given 1 or 2 g dose of ethanol extracts of panax ginseng, all subjects decreased ROS and MDA levels, 1 g dose improved GSH concentration and GSH-Rd activity, and 2 g dose decreased VAS score, and improved Mental NRS compared to placebo (10)

L-Theanine 

200-400 mg, total per day, minimum 4 weeks (8)(20

  • Alleviated stress-related ailments demonstrated by improved scores in Self-rating Depression Scale, State-Trait Anxiety Inventory-trait, and Pittsburgh Sleep Quality Index (PSQI) compared to placebo (8)
  • L-theanine improved acute stress response demonstrated by a decrease in heart rate and salivary immunoglobulin A (Ig-A), when given acute doses at the start and midway through a stressful procedure compared to placebo (11)
  • Systematic review of nine articles found l-theanine to be effective in reducing stress and anxiety for people exposed to stressful conditions (20)
  • Decreased stress as shown by attenuation of blood-pressure increase and decrease in tension-anxiety score compared to placebo (21)

B Complex 

Variable based on ingredient and formulation, use for a minimum of 12 weeks 

  • Systematic review and meta-analysis of 18 articles found B vitamins to have an overall positive effect on mood or facets of mood with a particularly significant benefit to stress (22)
  • Psychological strain and mood from occupational stress improved shown by decreased levels of confusion, depression, dejected mood, or feelings of strain with supplementation over a 3 month period (19)
  • B complex supplementation following a natural disaster resulted in improved stress and anxiety to a greater extent than those in the single-nutrient control group (9)
