Stress Management
1. Root Cause Overview
Chronic psychological stress activates the HPA axis and sympathetic nervous system, leading to sustained elevation of cortisol, adrenaline, and inflammatory cytokines. Over time, this drives HPA dysregulation, immune suppression, gut permeability, cardiovascular disease, metabolic dysfunction, and accelerated ageing. Stress is both a root cause and an amplifier of virtually every functional medicine condition. Effective stress management requires addressing the physiological stress response, not just the psychological perception of stress.
2. Common Signs & Symptoms
- Anxiety, worry, racing thoughts
- Irritability and emotional reactivity
- Difficulty concentrating or making decisions
- Fatigue despite adequate sleep
- Muscle tension, jaw clenching, headaches
- Digestive symptoms: IBS, nausea, appetite changes
- Sleep disturbances (difficulty falling or staying asleep)
- Elevated resting heart rate or blood pressure
- Recurrent infections (immune suppression)
- Skin flares (eczema, psoriasis, acne)
3. Labs to Consider
Magnesium status, B12, vitamin D, thyroid panel, CBC/CMP when fatigue or anxiety is persistent.
Choose the lab option based on what you want to assess within this root cause.

4. Clinical Priorities
Assess for the different domains contributing to stress load, which may include occupational, relational, financial, physiological, inflammatory, and sleep-related factors. Implement evidence-based stress-reduction practices while also correcting likely nutrient depletions associated with chronic stress, such as magnesium, vitamin C, zinc, and B-vitamins. Use adaptogens as adjuncts to, not replacements for, lifestyle and behavioural interventions.
Where to Start: Top 2 Supplements
The most evidence-backed adaptogen for stress and anxiety reduction. Multiple RCTs confirm significant reduction in perceived stress, cortisol levels, and anxiety scores. Well-tolerated, safe for long-term use, and addresses both the physiological and psychological dimensions of stress.
Chronic stress depletes magnesium — the 'anti-stress mineral'. RCT evidence shows the combination of magnesium + B6 is superior to magnesium alone for severe stress. Magnesium supports GABA receptor function (calming), while B6 is a cofactor for serotonin and GABA synthesis.
5. Diet Strategy
Stabilise blood sugar to prevent cortisol spikes: regular meals with protein, fat, and fibre; avoid skipping meals. Reduce caffeine and alcohol — both dysregulate the stress response. Emphasise magnesium-rich foods (dark leafy greens, nuts, seeds, dark chocolate), B-vitamin-rich foods (whole grains, legumes, eggs), and vitamin C-rich foods (citrus, peppers, kiwi). Omega-3 fatty acids from fatty fish reduce cortisol and inflammatory stress markers.
6. Lifestyle Strategy
Daily stress reduction practice is non-negotiable: mindfulness meditation (10–20 min/day), diaphragmatic breathing (4-7-8 technique), progressive muscle relaxation, or yoga. Regular aerobic exercise (150 min/week) is one of the most effective stress-reduction interventions. Nature exposure (forest bathing, outdoor time) significantly reduces cortisol. Social connection and meaningful relationships are powerful stress buffers. Limit news and social media consumption.
7. Supplement Strategy
Full supplement list below. See Section 4 (Clinical Priorities) for the recommended Top 2 starting supplements. Add additional supplements based on lab results and clinical response at 4–6 week reassessment.
| Supplement | Dosage | Indication | Evidence | Key Results | Example |
|---|---|---|---|---|---|
| Ashwagandha (Withania somnifera, standardised extract) [1] Mild GI upset; avoid in pregnancy; caution with thyroid medications | 240–600 mg/day | Stress and anxiety reduction; cortisol modulation; HPA axis support | Randomised, double-blind, placebo-controlled trial (60 days) | Significant reduction in stress and anxiety scores; reduced serum cortisol; improved sleep quality | Jarrow Formulas Ashwagandha KSM-66 |
| Magnesium + Vitamin B6 (combined) [2] Loose stools at high magnesium doses; B6 neuropathy at very high doses (>500 mg/day) | 300 mg magnesium + 30 mg vitamin B6/day | Stress-induced magnesium depletion; GABA cofactor; neuromuscular relaxation | Randomised, double-blind, placebo-controlled trial (8 weeks) | Superior reduction in severe stress scores vs. magnesium alone; improved sleep and anxiety | Pure Encapsulations Magnesium Glycinate + B6 |
| Saffron Extract (Crocus sativus, affron®) [3] Generally well tolerated; mild GI upset; avoid high doses in pregnancy | 28–30 mg/day standardised extract | Anxiety and mood support; serotonin modulation; stress resilience | Randomised, double-blind, placebo-controlled trial (8 weeks) | Significant improvement in mood, stress, and cognitive function; reduced anxiety and depressive symptoms | Integrative Therapeutics Saffron |
| Korean Red Ginseng (Panax ginseng) [4] Insomnia if taken late in the day; headache; avoid in hypertension and hormone-sensitive conditions | 1,000–3,000 mg/day standardised extract | Adaptogen; stress resilience; HPA axis modulation; fatigue reduction | Randomised, double-blind, placebo-controlled trial (6 weeks) | Significant reduction in stress, fatigue, and anxiety scores in high-stress adults | Korea Ginseng Corp Red Ginseng |
| Lavender/Chamomile Aromatherapy (topical/inhalation) [5] Skin irritation if applied undiluted; rare allergic reactions; avoid in young children (lavender) | 3 drops of 1.5% lavender and chamomile essential oil blend (inhalation/topical) | Acute stress and anxiety reduction; autonomic nervous system regulation | Randomised, controlled trial (30 nights) | Significant reduction in depression, anxiety, and stress scores; improved sleep quality | Aura Cacia Lavender Essential Oil |
8. Safety Notes
Supplements are adjuncts to, not replacements for, evidence-based psychological interventions (CBT, mindfulness-based stress reduction). Refer for clinical anxiety or depression requiring pharmacological or psychotherapeutic management. Korean Red Ginseng is contraindicated in hypertension and hormone-sensitive conditions. Avoid high-dose adaptogens in pregnancy without specialist guidance.
