Sleep Supplement Overview
Quality sleep is an essential recovery factor. Although sleep hygiene should be addressed first, some supplements can significantly improve sleep quality, sleep onset speed and deep sleep duration.
| Supplement | Dose | Mechanism | Level of Evidence |
|---|---|---|---|
| Magnesium Glycinate | 200-400 mg before bed | GABA receptor activation, muscle relaxation | High |
| Melatonin | 0.3-5 mg, 30-60 min before bed | Circadian rhythm regulation | High |
| Glycine | 3-5 g before bed | Body temperature reduction, neurotransmitter | Moderate-high |
| Ashwagandha | 300-600 mg (standardized) | Cortisol reduction, GABA mimicry | Intermediate |
| GABA | 500-1000 mg before bed | Direct inhibitory neurotransmitter | Low-moderate |
| L-theanine | 200-400 mg | Increasing alpha wave activity in the brain | Intermediate |
| Valerian Root | 300-600 mg | Modulation of GABA metabolism | Intermediate |
Magnesium — Sleep Mineral #1
Magnesium is arguably the most important mineral for sleep quality. It acts as a natural NMDA receptor antagonist and GABA agonist — calming the nervous system and relaxing the muscles.
For athletes, magnesium is especially important because intense training increases magnesium loss through sweat. Magnesium deficiency is associated with poorer sleep quality, muscle cramps and increased cortisol.
Melatonin — Circadian Rhythm Regulator
Melatonin is a hormone naturally produced by the pineal gland in darkness. It signals to the body that it is time to sleep. Supplements can help with:
- For jet lag — helps adapt to a new time zone
- For shift work — helps fall asleep during the day
- For delayed sleep phase disorder — for "night owls" to fall asleep earlier
Supplement Combination Strategies
Synergistic effect — magnesium relaxes muscles, glycine lowers body temperature. 200 mg magnesium + 3 g glycine — an excellent combination.
Suitable for jet lag or shift work — melatonin regulates rhythm, magnesium improves sleep quality.
Stress-reduction combination — ashwagandha lowers cortisol, magnesium calms the nervous system.
L-theanine increases alpha waves in the brain, magnesium helps with physical relaxation.
❓ Frequently Asked Questions
Most methods are suitable for most people, but it is always recommended to consult a doctor or physiotherapist before starting a new program.
Results depend on individual characteristics, consistency and the complexity of the problem. Some people notice improvement within 1-2 weeks, others need 4-6 weeks.
Yes, often the best results are achieved by combining several recovery methods. For example, stretching + sleep hygiene + proper nutrition give a synergistic effect.
