Quick answer: Sleep is when your brain clears waste, your body repairs tissue and your hormones reset. The biggest improvements usually come from habits: morning light, a consistent schedule, a cool dark room and less evening screen time. Magnesium, glycine, L-theanine, chamomile, valerian and reishi can gently support sleep, and low-dose melatonin is best for timing problems such as jet lag.
Why sleep matters
- The brain’s glymphatic system clears waste during deep sleep
- Growth hormone peaks to repair tissues
- Memories consolidate
- Cortisol drops to its daily low
Sleep habits come first
- Get morning sunlight within an hour of waking
- Keep a consistent sleep and wake time
- Dim lights and limit screens for an hour or two before bed
- Keep the bedroom cool, dark and quiet
- Finish caffeine by noon and eat dinner a few hours before bed
Supplements that may help
- Magnesium glycinate: supports relaxation (see who should consider magnesium)
- Glycine: may help you fall asleep by lowering core body temperature
- L-theanine: calms without sedation
- Chamomile (apigenin): a gentle calming herb
- Valerian, lemon balm and passionflower: traditional calming herbs
- Reishi mushroom: traditionally used for calm and sleep
- Phosphatidylserine: may help when evening cortisol runs high
- Melatonin: best for jet lag and shift work; low doses often work as well as high doses
Amounts should be individualized. If you work with me, the products I use are in my Fullscript dispensary.
Is testing helpful?
If sleep problems persist, looking at cortisol patterns, ferritin, magnesium and thyroid can help, and a sleep study is important if sleep apnea is possible. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Sleep and healthy aging
Deep sleep is when the body does much of its repair: clearing damaged proteins, repairing DNA, supporting mitochondria and resetting hormone signals. Chronic short sleep is linked with faster biological aging. Related: sleep optimization for longevity and the glymphatic system.
Safety
Sleep supplements can add to the effects of alcohol and sedating medications. Valerian can cause morning grogginess in some people. Melatonin is not recommended in pregnancy without guidance. Do not drive if you feel drowsy.
When to see a naturopathic doctor
- Trouble falling or staying asleep for more than a few weeks
- You wake unrefreshed despite enough hours in bed
- Sleep problems came with perimenopause, stress or mood changes
- You rely on sleep aids and want a gentler plan
See a medical provider promptly for loud snoring with pauses in breathing, gasping at night, or falling asleep while driving. These can be signs of sleep apnea and need evaluation.

Frequently asked questions
What is the best natural sleep aid?
It depends on why you cannot sleep. Magnesium and glycine help many people relax; melatonin helps with timing problems.
Is melatonin safe every night?
Short-term use is generally considered safe for adults. Lower doses often work well. Talk with your provider about long-term use.
Why do I wake at 3 a.m.?
Common causes include blood sugar dips, stress hormones, alcohol, perimenopause, sleep apnea and needing to urinate.
Can supplements replace treatment for insomnia?
Cognitive behavioral therapy for insomnia (CBT-I) is very effective. Supplements can support it.
