How to reduce stress and cortisol using supplements. From ashwagandha to magnesium — scientifically based methods for athletes.

Stress is essential for progress in sport — it is the driver of training adaptation. However, CHRONIC stress (both physical from overtraining and psychological from life) becomes an enemy: elevated cortisol breaks down muscle, weakens immunity, worsens sleep and slows recovery. Supplements can help manage cortisol, but they are an auxiliary tool — first, the causes of stress need to be addressed.
| Supplement | Mechanism of Action | Dose | When Does It Work? |
|---|---|---|---|
| Ashwagandha (KSM-66) | Cortisol reduction, adaptogen | 300-600 mg/day | After 2-4 weeks of regular use |
| Magnesium Bisglycinate | GABA receptor activation, muscle relaxation | 300-400 mg | Within 30-60 min (acute effect) |
| L-theanine | Alpha brain waves, GABA, serotonin | 200-400 mg | Within 30-40 min (without sedation) |
| Rhodiola (Rhodiola rosea) | Adaptogen, stress resistance, energy | 200-600 mg/day | After 1-2 weeks, preferably in the morning |
| Phosphatidylserine | Suppression of cortisol response after training | 400-800 mg | After intense training or before sleep |
Phosphatidylserine 600 mg after training + Magnesium before sleep. Phosphatidylserine suppresses the cortisol response after intense exertion. Magnesium improves sleep, which is the best anti-stress "medicine".
Ashwagandha KSM-66 600 mg + L-theanine 200 mg (when needed). Ashwagandha reduces baseline cortisol levels in the long term. L-theanine quickly calms during acute anxiety without drowsiness.
L-theanine 200-400 mg 1 hour before the start. Reduces anxiety but not energy. Unlike prescription medications, L-theanine does not cause sedation or dependence.
Magnesium bisglycinate 400 mg + GABA 500 mg + Melatonin 0.5 mg. GABA directly affects the nervous system. Magnesium relaxes muscles. Melatonin helps you fall asleep.
